INTRODUCTION
Although Opopaea is one of the most diverse and widely distributed oonopid genera, we know surprisingly little about the overall diversity of this group in Madagascar. Opopaea currently consists of 50 valid species of which six are considered to be misplaced in the genus (Platnick, 2012). The genus is known from Africa, Madagascar and the surrounding islands, the Middle East (Israel, Egypt), Bhutan, Australia, Southeast Asia (Sri Lanka, the Philippines, China, Thailand), and the New World, although Opopaea has been hypothesized as introduced (nonnative) in the latter region. In fact, no native American species have been found (Platnick and Dupérré, 2009) and the only two species present in America are pantropical (O. deserticola Simon and O. concolor (Blackwall)). There are also several undescribed species from Africa and from Australia ( http://research.amnh.org/oonopidae/).
Opopaea are found in virtually all parts of the former supercontinent Gondwanaland except New Zealand and Antarctica. The presence of cosmopolitan species such as Opopaea deserticola and O. concolor suggests that the genus may either be old and its oldest species were already distributed in those continents before the break up of Gondwanaland or that Opopaea may have a more complex history of vicariance associated with more recent dispersal due to human interference. Although the genus is very diverse, both in Africa and Australia, their phylogeny (Andriamalala and Hormiga, in prep.) suggests that Opopaea is most probably of African origin, as the two cosmopolitan species Opopaea deserticola and O. concolor are more closely related to the African species than to the Australian and Asian species. The Opopaea fauna of Madagascar was completely unknown before our work.
Opopaea are small to medium-sized oonopids, ranging from 1.0 to 2.4 mm in body length, with the abdomen completely covered with ventral and dorsal scuta. They belong to the “Loricatae” and “Opopaea group” (Saaristo, 2001). Their tarsal organ shows a pattern of 3-3-2-2 sensilla distribution, which places them within the subfamily Oonopinae (Platnick et al., 2012).
Although members of the genus Opopaea can be differentiated from other oonopid genera by a combination of characters (see Diagnosis section below), the circumscription of the genus is still ambiguous, in part because Opopaea also shares some but not all of these characters with other oonopid genera. For example, many genera, such as Epectris Simon (1893), Camptoscaphiella Caporiacco (1934), Brignolia Dumitrescu and Georgescu (1983), Ischnothyreus Simon (1893), Malagiella Ubick and Griswold (2011), and Prethopalpus Baehr et al. (2012), have sclerotized palps like those of Opopaea (Baehr and Ubick, 2010; Baehr et al., 2012; Kranz, 2011; Platnick and Duperré, 2010–2011). Malagiella, Camptoscaphiella, and Prethopalpus share with Opopaea the enlarged palpal patella also originating subbasally from the palpal femur, and in Malagiella the bulb and cymbium are also fused. The male palps of Brignolia, Epectris, and Prethopalpus have “fenestra” and the epigyna in these genera also have lateral apodemes as in Opopaea. In some species of Brignolia, and Epectris there are also striations on the lateral side of the carapace. However, none of the six aforementioned genera have all these characters in combination like Opopaea. For instance, in the females of Malagiella and Camptoscaphiella, while the male palpal patella is greatly enlarged as in Opopaea, the abdomen is only partially covered by a scutum, the epigynum is completely different and have an external copulatory orifice (see Ubick and Griswold, 2011: figs. 5, 105), and the carapace has no striations on the lateral sides. In addition, Camptoscaphiella and Prethopalpus have the bulb and the cymbium separated rather than fused as in Opopaea and the pedicel with neither the small, dorsolateral, triangular extensions nor the paired curved scutal ridges as in all Opopaea species (Baehr and Ubick, 2010; Baehr et al., 2012). Although Brignolia and Ischnothyreus both have pitch-black and heavily sclerotized palps, they have a normal-sized papal patella. The female genitalia of Ischnothyreus are very different from those of Opopaea; the abdomen is only partially covered with a scutum and the tarsi with an elongated distal tooth on the claws of leg IV of females (see Ubick and Griswold, 2011: fig. 59). Brignolia and Epectris female genitalia are quite similar to that of Opopaea's except for the presence in some species of a sclerotized structure of various forms (other than the parmula) in the area between the epigastric furrow and the groove joining the posterior spiracle, called here “postgynum nob”. Externally this structure has a slit on its lateral sides and could constitute the copulatory openings in those genera (see Platnick et al., 2011: fig. 69; Platnick and DuperrPlatnick and Duperréeacute;, 2009: figs. 132, 149, 150, 159). Likewise, it is important to note that the lack of a “postgynum depression,” a depression below the epigastric furrow (figs. 47–50) present in all Opopaea species, and the presence of a “posterior tubular process” (see Platnick et al., 2011: figs. 70, 71) also appear to differentiate Brignolia and Epectris from Opopaea. Epectris, which was previously placed within Opopaea as O. lena Suman, resembles Opopaea the most in overall somatic characters and could be Opopaea sister taxa. In fact, Epectris was erected as a new genus by Saaristo and Marusik (2008) based on the alleged absence of a palpal fenestra (a depression at the tip of the male palp; figs. 194, 226, 258, 290, 326, 357, 415), but later, Platnick and DuperrPlatnick and Duperréeacute; (2010) discovered the presence of the fenestra in Epectris palps (see Platnick and DuperrPlatnick and Duperréeacute;, 2009: figs. 153, 154). However, the palpal fenestra in Epectris and Brignolia differs from those of Opopaea as it is rather a depression instead of a hole.
Because of the aforementioned confusion about the generic limits, combined with Opopaea's almost cosmopolitan distribution, numerous species have been transferred in and out of Opopaea and several species from different parts of the world have been synonymized after revisionary treatments. For example, some species that clearly belong to Opopaea were initially described in Gamasomorpha Karsch (1881), and numerous species have been mistakenly assigned to Opopaea. Recently, in a revision of the New World Opopaea, O. devia Gertsch from Texas, O. guaraniana Birabén from Argentina, and O. bandina Chickering from Florida as well as Myrmecoscaphiella borgmeyeri Mello-Leitão from Brazil were all synonymized with Opopaea concolor, while O. timida Chickering, from Panama, was placed as a junior synonym of O. deserticola (Platnick and DuperrPlatnick and Duperréeacute;, 2009).
The Opopaea fauna from remote places rich in biodiversity like Madagascar is currently unknown. Malagasy organisms are known for their remarkable species richness and endemism (Goodman and Benstead, 2003; Griswold, 2003). Here, we describe the first Opopaea species from this island. Examination of museum collections and recent collections, including our own fieldwork in Madagascar, have revealed 27 Opopaea species of which 26 are new. In the last three years, five new species have been discovered from Africa (Saaristo and Marusik, 2008), seven from China (Tong and Li, 2010), and eight from Australia (Baehr, in press). Currently, there are 50 described species of Opopaea (Platnick, 2012). Many more may be discovered and some may need to be synonymized. Therefore, the genus needs to be revised and the species relationships within Opopaea need to be clarified in a phylogenetic framework.
METHODS
This project is part of the goblin spider Planetary Biodiversity Inventory ( http://research.amnh.org/oonopidae/), an effort to describe the goblin spiders (Oonopidae) of the world, including those from high-priority biodiversity hotspots like Madagascar (Mittermeier et al., 1997, 1999, 2004). More than 4000 Opopaea specimens from 67 localities in Madagascar have been collected by the Madagascar arthropod project carried out by the California Academy of Sciences (CASC) Entomology Department in collaboration with the Botanical and Zoological Park of Tsimabazaza (PBZT) (2000–2004) and the PBI project expedition (2009). Additional specimens were borrowed from the Royal Museum for Central Africa in Tervuren (MRAC), the American Museum of Natural History in New York (AMNH), the Field Museum of Natural History in Chicago (FMNH), and the Museum of Comparative Zoology at Harvard University (MCZ).
These samples encompass the diversity of the genus Opopaea in Madagascar as those surveys were conducted in more than 100 sites of varied vegetation, climate, elevation, and geological substrate in which different collecting methods (Winkler extractors and leaf-litter sifting, beating low vegetation, Berlese funnels, general collecting, and pitfall traps) were used to sample terrestrial arthropods (Fisher, 2005).
Morphological characters and locality data were used to discriminate species. We used the phylogenetic species concept sensu Wheeler and Platnick (2000) to hypothesize Opopaea species circumscription, that is, “the smallest aggregation of populations diagnosable by a unique combination of character states.” The male and female of each species, if both are known, are described. Species descriptions, illustrations, and measurements are based on five representative specimens of each species and sex whenever possible. Adult individuals representing the full range in overall size are chosen according to the degree of character variation and site locality to maximize the range of variation and geographic distribution considered. Descriptions were generated with the aid of the Planetary Biodiversity Inventory (PBI) descriptive goblin spider database and shortened whenever possible. All measurements are expressed in millimeters (figs. 1–4), and were taken using the measurement module of Leica Application Suite in a Leica MZ16 stereomicroscope. Size measurements were taken of males and females of each species, whenever possible, and are reported as ranges for each sex. In some species, there are fewer than five individuals available, so only those numbers are reported.
Specimens were examined using a Leica MZ APO and illustrated with a Leica MZ16 stereomicroscope with a Leica DFC 500 digital camera. SEM micrographs were taken with a LEO 143OVP scanning electron microscope. Specimens were dissected and cleaned ultrasonically before being transferred to 100% ethanol, and left to dehydrate for 24 hours. After dehydration, the specimens were critically point dried, mounted, and sputter coated with gold. For transmitted light microscopy, the specimens were made transparent by transferring them to methyl salicylate for a few minutes. Subsequently, the specimen was mounted in a microscope slide with a cover slip (see Grandjean, 1949) and examined/illustrated using an OLYMPUS BX51 compound microscope with a camera lucida. Specimens were drawn with graphite pencils and the drawings were scanned and further edited in Photoshop using a Bamboo Wacom tablet. For the male palp illustrations, the left palp was used. Female genitalia and tracheal system were dissected, and the soft tissue was digested with pancreatin enzyme complex (P1750 from Sigma-Aldrich; Alvarez and Hormiga, 2008). After removing any remaining tissues with a needle and forceps, the preparations were washed with distilled water and transferred to 75% ethanol for observation and illustration. Distribution maps were generated with the software DIVA-GIS (Elith et al., 2006). Distribution of suitable areas and climatic requirements for the genus in Madagascar were modeled from 93 Opopaea presence points taken from Opopaea occurrence data in Madagascar (after redundant points were removed), based on 20 environmental variables—altitude and 19 bioclimatic variables from WorldClim (30 arcsine seconds spatial resolution; Hijmans et al., 2005)—and using the software MAXENT (Philips and Dudik, 2008).

SYSTEMATICS
Family Oonopidae Simon, 1890
Opopaea Simon, 1891
Opopaea Simon, 1891: 560 (type species by monotypy Opopaea deserticola Simon).
Diagnosis:
Members of the genus Opopaea can be differentiated from those of other oonopid genera with fully fused sclerotized palps and with an enlarged palpal patella originating subbasally from the palpal femur (such as Camptoscaphiella, Epectris, Malagiella and Prethopalpus) by the following combination of characters present all at once:
Male palps completely sclerotized with a greatly enlarged palpal patella that often originates subbasally from the palpal femur, a completely fused cymbium and bulb (cymbiobulbus), and a palpal fenestra as a cavity, not a depression like the one found in Brignolia and Epectris (figs. 3, 224, 226); endites with a toothlike projection (figs. 29, 39); and only posterior spiracles connected by a groove (figs. 143, 175).
Females have various kinds of external genital structures (parmula) attached to their epigastric furrow; a depression in the epigastric region below the epigastric furrow (postgynum depression; Saaristo, 2001; Saaristo and Marusik, 2008) (figs. 4, 47, 48, 807, 808); and lack of an elongated distal tooth on the claws of leg IV (figs. 74, 75, 76).
Both sexes have: lateral striations on the carapace (figs. 9, 10, 12, 13); smooth sternum surface (figs. 11, 14, 15, 16); abdomen completely covered dorsally and ventrally with scuta; long and thin lateral apodemes that extend past the posterior spiracles (figs. 457, 460); pedicel tube with a pair of small dorsolateral, triangular extensions; and a pair of curved scutal ridges on the scutopedicel region (figs. 42, 45, 146, 211).

The tracheal system of all 26 Malagasy Opopaea consists of two large trunks arising just below the epigastric furrow from each of the two tracheal spiracles. Each tracheal trunk goes anteriorly through the pedicel into the prosoma and posteriorly each trunk branches into numerous tracheoles that spread in the abdomen (figs. 63–67). Epigynum internally with a T-shaped anterior sclerites (Asc) which ends posteriorly with a small median projection (Na, sensu Burger, 2009). The receptaculum is connected anteriorly to a short and straight tube (Gap) and bear at its anterior surface different numbers (three to four) and pattern of small holes that seems to have glands enclosed inside of them. Receptaculum inverted-arc shaped, of different size, always shorter than lateral apodemes and with a slit posteriorly (figs. 51, 60).
Phylogenetics:
The monophyly of Opopaea has not been tested yet in a phylogenetic framework. Putative synapomorphies for the genus could be the “postgynum depression” (figs. 47–50) and a series of holes on the anterior part of the receptaculum (fig. 54).
Composition:
There are currently 50 described species of Opopaea worldwide. Only the 27 species known from Madagascar are treated here: Opopaea andranomay, n. sp., O. ankarafantsika, n. sp., O. ankarana, n. sp., O. antsalova, n. sp., O. andringitra, n. sp., O. antsiranana, n. sp., O. bemarivo, n. sp., O. bemaraha, n. sp., O. berenty, n. sp., O. betioky, n. sp., O. concolor (Blackwall, 1859), O. itampolo, n. sp., O. kirindy, n. sp., O. manderano, n. sp., O. mahafaly, n. sp., O. manongarivo, n. sp., O. maroantsetra, n. sp., O. namoroka, n. sp., O. sandranantitra, n. sp., O. torotorofotsy, n. sp., O. tsimaloto, n. sp., O. tsimbazaza, n. sp., O. tsimembo, n. sp., O. tsinjoriaky, n. sp., O. tsingy, n. sp., O. vohibazaha, n. sp., and O. foulpointe, n. sp.
Natural History and Distribution:
In Madagascar, Opopaea species were found all over the island, in different types of habitat, such as montane rainforest, tropical dry forest, spiny/thicket forest, gallery forests, tropical deciduous forest, secondary forests near the beach, and mango and palm plantations from 10–1990 m elevations. Opopaea have also been collected in the litter, in dead wood, from trees, and even in the canopy. Given their distribution, one would think of Opopaea as a generalist, however, the results from the MAXENT model of their distribution suggests that Opopaea species are very sensitive to precipitation. Most of the predicted suitable areas for the genus are found in the eastern, humid part of the island, especially in the northeast and the southeast of Madagascar (map 6) and the MAXENT model's internal jackknife test of variable importance showed that precipitation variables such as “Precipitation of driest month (bio14)” and “Precipitation of wettest quarter (bio16)” were the two most important predictors of Opopaea's habitat distribution in Madagascar (table 2).TABLE 1

Opopaea concolor (Blackwall, 1859)
Oonops concolor Blackwall, 1859: 265 (male and female syntypes from Madeira, should be in the Department of Entomology, Oxford University, not examined).
Opopaea concolor: Kulczynski, 1899: 339, pl. 6, fig. 25; Wunderlich, 1987: 63, figs. 24–26; Saaristo, 2001: 333, figs. 22, 23a, 23b, 24a, 24b, 25a, 25b, 26a, 26b, 27; Saaristo, 2007: 136, figs. 90–92; Saaristo and Marusik, 2008: 20, figs. 13–21, 119–121, 123–132, 193, 199, 218, 228; Platnick and Dupérré, 2009: 43, figs. 73–104.
Diagnosis:
Females of O. concolor can be easily recognized by a small sclerotized, teardrop-shaped parmula, completely detached from a thin, sclerotized scutal ridge and a postgynum depression constricted in its median part where it surrounds the parmula (figs. 103, 123).
Note:
No males of this species have been found from the Madagascar collection studied. Therefore, only the female is described here. However, illustrations of a male from Mexico (PBI_OON 34433) from our loans are provided.

Diagnosis:
Males of andranomay resemble those of O. foulpointe in having small eyes and very long and thin legs (figs. 141–142 [andranomay], 458–459 [foulpointe]), and O. manongarivo, and O. sandranantitra, by having a cymbiobulbus almost the same length as the patella (figs. 151–152, 629–630, 731–732), but can be distinguished from other Opopaea species by the fenestra anterior top raised into a sclerotized dome, which abruptly and steeply slopes toward the tip (figs. 151–152, 155–156, 165–166). Females of andranomay can be easily recognized by a thick scutal ridge with a thick boatlike sclerotized median area bearing a small elliptical parmula (figs. 137, 157–158).
Description:
Male (holotype) (PBI_OON 34422). Medium-sized to large species. Total length 1.71. Color: brown orange (figs. 141–144). Carapace: pars cephalica elevated posteriorly with one continuous row of four recurved denticles (figs. 148, 149). Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum absent. Cheliceral paturon long and thin distally but heavier and bearing lateral boss proximally, usually detached from clypeus posterior margin and directed obliquely (figs. 147, 148). Eyes small. ALE largest. ALE oval, PME oval, PLE circular; PME darkened compared to other eyes; posterior eye row straight viewed from above, slightly procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, with radial furrows between coxae; surface smooth, without pits, shape of posterior part between coxae IV hexagonal, not constricted. Lateral margins of area between coxae III unmodified, without lumps; setae abundant and evenly distributed, originating from surface, without hair tufts (fig. 150). Cymbiobulbus with a short sclerotized tip, and three protuberances: two on posterior margin (one small, distal and the other large, proximal) and one on retrolateral margin (figs. 152, 156). Palpal femora half the size of palpal patella and inserted almost medially to it. Fenestra large and located at the anterior part of the cymbiobulbus at one third of its length (figs. 135–136, 151–152, 155–156, 159–166).

Diagnosis:
Males of O. andringitra can most easily be distinguished from those of other Opopaea species by the rectangular shape of the distal part of the cymbiobulbus, which is abruptly depressed dorsally, and the truncated palpal tip with two very short but sharp, sclerotized extensions (figs. 167–168, 183–184, 187–222). Females of O. andringitra can easily be recognized by a thick and divided scutal ridge, forming a reverse triangle medially and bearing a tiny, dark parmula anteriorly, and a short, sclerotized extension posteriorly (figs. 169, 189–190).
Description:
Male (holotype) (PBI_OON 35038). Large species. Total length 1.73. Color: orange. Carapace: pars cephalica elevated posteriorly with one row of four continuous hairs, carapace anteriorly narrowed to about one third its maximum width (figs. 180, 181). Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum absent. Eyes large. ALE largest. ALE and PLE oval, PME squared; PME darkened compared to other eyes; posterior eye row straight viewed from above, procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius.

ALE more or less circular, PME squared and PLE oval; PME darkened compared to other eyes; posterior eye row straight viewed from above, slightly procurved from front; ALE separated by almost their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide with radial furrows between coxae; surface smooth and shiny, without pits, shape of posterior part between coxae IV wider proximally, but thin and constricted distally (fig. 278). Lateral margins of area between coxae III unmodified, without lumps; setae sparse, dark, needlelike, densest laterally, originating from surface, without hair tufts (figs. 275–278). Abdomen oval not flattened laterally toward posterior end. Palp posterior margin straight, with two barely visible protuberances: one small and wide proximally, small and the other more or less sharp distally (fig. 283). Palpal femora half the size of palpal patella and inserted medially to it. Palpal fenestra large, elongated and enlarged anteriorly, located near the tip of the palp, fenestra top rose toward the tip (figs. 263–264, 279–280, 283–284, 287–295).
Female (allotype) (PBI_OON 35038). Total length 2.38. As in male but larger, color orange, abdomen oval, and not flattened posteriorly. Epigynum scutal ridge more or less thick and straight bearing a round medium-sized parmula within its median part (figs. 265, 285–286).

ALE, PME oval, PLE circular; posterior eye row straight viewed from above, slightly procurved from front; ALE separated by their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide with radial furrows between coxae, surface smooth and shiny, without pits, shape of posterior part hexagonal between coxae IV not constricted (fig. 345). Lateral margins of area between coxae III unmodified, without lumps, setae sparse, more abundant and on margins, originating from surface, without hair tufts. Palp with three posterior protuberances: one larger and smoother on proximal margin, one smaller and very sharp on distal margin and a small one on retrolateral margin. Palpal femora half the size of palpal patella and inserted at one third of patella length. Palpal fenestra large, elongated, enlarged posteriorly and located at one third the length of the palp, fenestra barely raised and sclerotized anteriorly (figs. 115–116, 365–366, 369–370, 373–381).
Female (allotype) (PBI_OON 35139). Total length 1.58. As in male but larger, color orange, abdomen oval and not flattened posteriorly. Postgynum depression short and narrow, ridge more or less thin and weakly sclerotized (figs. 332, 352–353).

Opopaea berenty, new species
Types:
Male holotype and female allotype from Toliara province: Réserve privée de Berenty, forêt de Bealoka, Mandraré river, 14.6 km 329° NNW Amboasary, gallery forest, 24°57′25″S, 46°16′17″E, 35 m, ER19, sifted litter (leaf mold, rotten wood, 03–08 February 2002, coll. B.L. Fisher et al., BLF5316 (CASC PBI_OON 2766).
Diagnosis:
Males of O. berenty resemble those of O. bemaraha in having the shape of the cymbiobulbus, one third shorter than the patella, with a more or less round anterior edge, and the posterior edge of the cymbiobulbus in between the two posterior protuberances with a sharp, thin bladelike area, but can be most easily distinguished by having the area below the palpal fenestra darkened and sclerotized on the retrolateral side (figs. 403, 407) and the shape of the abdomen laterally flattened (figs. 396, 397). Females of O. berenty are also very different from those of O. bemaraha and other Opopaea species in having a more or less wide V-shaped postgynum depression that opens posteriorly and with a nonsclerotized ridge (fig. 409). At the epigastric furrow the scutal ridge is a very thin, divided, and with a tiny parmula sitted on a rectangular sclerotized structure (figs. 392, 409–410).
Description:
Male (holotype) (PBI_OON 2766). Small to medium-sized species. Total length 1.40. Color: yellowish orange to orange.

Area between coxae III unmodified, without posterior lumps; setae sparse, densest at margins, originating from surface, without hair tufts (figs. 399–402). Palp cymbiobulbus tip with short, liplike, more or less sclerotized extensions on the anteroventral side, posterior margin with two protuberances: a smooth and large proximal one and the other small and sharp distally, separated by a sharp, thin bladelike area in between. Palpal fenestra large and elongated (oval), oriented more or less vertically and located near the end of the palp, area before fenestra anterior top not raised, round and short, slightly sclerotized, sloping downward toward the tip. Palpal femora about a half of the length of palpal patella and inserted almost medially to it (figs. 387–388, 403–404, 407–408, 411–418).

Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum present, undivided. Cheliceral paturons long, thin, with proximal bosses, directed obliquely, usually detached from the posterior margin of the clypeus (fig. 465 ). Eyes medium sized. ALE and PME largest. ALE, PME, and PLE oval; PME darkened compared to other eyes, posterior eye row straight viewed from above, slightly procurved from front; ALE, ALE-PLE, and PLE-PME separated by less than their radius, PME touching throughout most of their length. Sternum longer than wide with radial furrows between coxae, surface smooth, without pits, shape of posterior part between coxae IV constricted then enlarged posteriorly, slightly swollen, especially in males (figs. 468, 469). Area in front of coxae III, each with two lateral lumps, setae abundant, evenly distributed, originating from surface, without hair tufts (figs. 466, 468, 469). Posterior margin of cymbiobulbus with two huge protuberances, both distally and proximally. Fenestra circular, anterior top not sclerotized. Palpal femora almost the same length as palpal patella and inserted at the posterior end of patella (figs. 452, 453, 470, 471, 474, 475, 478–486).

Opopaea mahafaly, new species
Types:
Male holotype and female allotype from Toliara province: Réserve spéciale de Beza Mahafaly, 26 km ENE Betioky, 23°39′18.2″S, 44°37′58.8″E, 135 m, sifted litter, gallery forest, 23 April 1997, B.L. Fisher (CASC PBI_OON 34407).
Diagnosis:
Males of O. mahafaly resemble those of O. bemaraha in having a cymbiobulbus with a tip that opens into a small hole, but can be distinguished by the shape of the cymbiobulbus, which is flattened on prolateral side and with the upper part almost arclike (figs. 569–572) and a very simple, narrow tip that curves upward (fig. 577), instead of downward or on the lateral side like in O. tsimbazaza and O. bemaraha, respectively. Females of O. mahafaly resemble those of O. andringitra in having the scutal ridge thick and posteromedially drops down into a small reverse triangle shape, but can be differentiated by the undivided, unsclerotized scutal ridge and the shape and location of the small parmula, far above the epigastric furrow (figs. 547, 567, 568).
Description:
Male (holotype) (PBI_OON 34407). Small to medium-sized species. Total length 1.32. Color: yellowish orange.

Lateral margins of area between coxae III unmodified, without lumps; setae sparse, dark, needlelike, densest laterally, originating from surface, without hair tufts (figs. 625–628). Palp cymbiobulbus slightly curved downward, with one posteromedian protuberance. Palpal fenestra large, more or less circular, enlarged anteriorly and located at one third of the palp. Fenestral top flat. Cymbiobulbus almost of the same length and color as patella. Femur longer, inserted at about one third the length from the posterior end of patella (figs. 613, 614, 629, 630, 633, 634, 637–647).
Female (allotype) (PBI_OON 3847). Total length 1.74. Abdomen round and not flattened laterally toward posterior end. Postgynum depression as wide as the distance between the two lateral apodemes and as long as one third the distance separating the epigynal furrow and the line uniting the tracheal spiracles.

Males of O. tsingy resemble those of O. namoroka in having the tip of the cymbiobulbus short, sharp, and with a sclerotized compact extension, but can be distinguished by having the tip extension not folded, but longer and pointing more or less forward. The fenestra is also larger and more or less circular (figs. 880, 881, 896, 897, 900, 901, 904–911). Females of O. tsingy can be recognized by the weakly sclerotized scutal ridge, medially bearing a thickened arclike structure with a small, thin, and cylindrical parmula on its upper surface (figs. 882, 902, 903).
Description:
Male (holotype) (PBI_OON 3792). Small species. Total length 1.47. Color: dark orange.

Opopaea vohibazaha, new species
Types:
Male holotype and female allotype from Antsiranana: 7.2 km 142° SE Antsiranana ( = Diego-Suarez), Montagne des Français, 12.32278°S, 49.33817°E, 180 m. 23–25 February 2001, L.J. Boutin coll. (CASC PBI_OON 35032).
Etymology:
The species epithet is a name in apposition taken from the type locality “Montagne des Français” translated into Malagasy.
Diagnosis:
Males of O. vohibazaha can be most easily distinguished from those of other Opopaea species by the shape of the cymbiobulbus, which tapers anteriorly with the dorsal margin curved in an arc shape and the posterior margin (ventral) straight with one small and sharp distal protuberance, and by the cymbiobulbus tip having a sclerotized truncated, leaflike extension (figs. 172, 173, 955, 956, 959, 960, 963–973). Females of O. vohibazaha can be easily recognized by their very simple epigynum, with a short and narrow postgynum depression, and a divided scutal ridge bearing a small round parmula within its median part (figs. 174, 961, 962).
Description:
Male (holotype) (PBI_OON 35032). Medium-sized to large species. Total length 1.56. Color: orange. Carapace: pars cephalica elevated posteriorly with one row of two widely separated sets of four denticles, three of which bear long, and thick black needlelike hairs.
