The Cuban fauna of the circum-Caribbean goblin spider genus Stenoonops Simon includes at least three species, newly described as S. tobyi, S. schuhi, and S. brendae. Longoonops Platnick and Dupérré, previously known only from Central America, Jamaica, and the Virgin Islands, is newly recorded from Cuba, where it is represented at least by L. ellae, new species. Stenoonops noctucus Chickering, from the Virgin Islands, is transferred to Longoonops.
ClavicorniaKormilev, 1960, representing the subfamily Mezirinae, is recorded from China for the first time. A new aradid, Clavicornia schuhi, new species, is described. A key to known species and subspecies of this genus is given and photos of the diagnostic morphological features of the new species are provided.
From Amazonia, Brazil, a new genus of apterous Mezirinae, Tobyschuhaptera gen.n., containing the new species. T. amazonica sp.n. is described and illustrated and compared with other apterous Neotropical Mezirinae.
A female of Schuhacantha bifurcata gen. n. et sp. n. (Hemiptera: Heteroptera: Colobathristidae: Colobathristinae) is described from continental Malaysia (Pahang). The autapomorphies of the genus are a robust bifurcate process situated at the middle lobe of the pronotum and an extremely short labium; a potential synapomorphy with Centromus Bergroth, 1910 is a strongly protruding, bill-shaped ovipositor. The first key to Eastern Hemisphere genera of the Colobathristidae which are distinct from the Neotropical fauna is provided. Morphology as well as diagnostic and functional significance of some structures (antennal sclerite, pronotal process, evaporatorial system, abdominal laterotergites, forewing venation, femoral spine, female terminalia) are discussed.
Nisoscolopocerus schuhi, new species, assigned to the family Coreidae (Coreini), is described from Mexico as the second member of the genus. The genus and the previously known species N. apiculatus are redescribed. Dorsal view photographs, drawings of the parameres, and key to both species are provided.
Four new species of Vazquezitocoris Brailovsky from Chile, Ecuador, and Peru are described. Dorsal and lateral view habitus, head, antennae, pronotum, female genital plate, parameres, and male genitalia capsule are illustrated; and a key to the known species is included.
The present study summarizes knowledge about phylogenetic relationships of the heteropteran infraorder Gerromorpha. A phylogeny for all families and subfamilies, and for all genera but those assigned to the two most diverse families, Veliidae and Gerridae, is compiled from the many studies by the late Dr. Nils Møller Andersen. Comparisons with recently published studies, including DNA sequence data show that the superfamilies Hydrometroidea and Gerroidea, the family Veliidae, the subfamily Mesoveliinae, and the genera Mesovelia and Microvelia are probably not monophyletic, and that Paraphrynoveliidae, Gerridae, Madeoveliinae, Ocelloveliinae, Veliinae, Haloveliinae and Gerrinae are without convincing diagnostic morphological characters. In Gerridae, phylogenetic hypotheses are available for most subfamilies, and are evaluated against more recent studies indicating that the tribes Metrocorini and Metrobatini, and even well-known genera, such as Aquarius, Limnometra, Tenagogonus and Halobates, are not monophyletic. As taxonomic classifications should be based on observable morphological characters, and at the same time reflect phylogenetic relationships, a considerable task lays ahead in obtaining material of key taxa for DNA sequencing, and in identifying and redescribing clades based on new combinations of diagnostic characters.
Schuhirandella fulva, a new genus and new species from Western Australia, is described. A differential diagnosis for the genus is given, and is compared to other monaloniine and odonielline Bryocorinae. Digital images of habitus, SEM images, drawings of male and female genitalia, and information on host plants are provided.
Three new species of the genus Leprocapsus Poppius from Indonesia, L. irianjayensis n. sp. and L. parvus n. sp. (Irian Jaya), and L. schuhi n. sp. (Sulawesi), are described. A color photograph of the adult and illustration of the antennal segments I and II of each treated taxa, dorsal habitus drawing of L. schuhi, illustration of the male genitalia of L. parvus, and scanning electron micrographs of selected structures of L. irianjayensis, L. schuhi, and L. scutellaris are provided. A key to all known species, diagnosis and the distribution map of the genus Leprocapsus are given.
Palaucoris tobyi sp. nov. is described from Sulawesi, Indonesia. Diagnosis, digital habitus images, illustrations of male and female genitalic structures, scanning micrographs of diagnostic morphological structures are provided for the new species and related taxa. The subfamily placement of the genus Palaucoris is briefly discussed.
Oncerometopus atriscutis Knight and Prepops rubroscutellatus (Knight) are plant bugs of the tribe Restheniini and subfamily Mirinae, largest of the eight mirid subfamilies. Both species were described in the late 1920s from a few locales in Arizona and New Mexico (also Colorado in the case of P. rubroscutellatus); their host-plant relationships have remained undocumented. We give additional distribution records of O. atriscutis from Arizona (3 counties, 6 sites), New Mexico (11 counties, 35 sites), and Texas (3 counties, 3 sites; new state record) and P. rubroscutellatus from Arizona (3 counties, 3 sites) and New Mexico (9 counties, 29 sites). Their seasonal histories are based mainly on regular sampling of Apache plume, Fallugia paradoxa (D. Don) Endl. ex Torr.; Rosaceae), from mid-July 2009 to mid-May 2012 at a Chihuahuan Desert site east of Las Cruces (Doña Ana Co.), New Mexico, where the bugs were syntopic. Supplemental data on seasonality were obtained from periodic collections from Apache plume in southwestern states. Regular sampling near Las Cruces, as well as supplemental collecting, indicated that both restheniines are bivoltine. Overwintered eggs hatched during the last two weeks of March at the main study site, and first-generation adults of both species appeared by mid-April and were present until early May. Nymphs of a second generation were present from early June to October (fifth instars occasionally were found in November), with adults present as late as the end of November. In the Southwest, both plant bugs were found only on Apache plume; the 1926 record of O. atriscutis from “Cowania sp.” (Rosaceae) in the Chiricahua Mountains of Arizona is considered an incidental occurrence of adults or a misidentification of Fallugia paradoxa.
A new species of plant bug, Prepops schuhi, is described from Rio Grande do Sul State, Brazil. Illustrations of the adult, male and female genitalia are provided to assist identification.
The new stenodemine mirid, Trigonotylus schuhi n. sp., is described from central Oregon, feeding on Poa secunda J. Presl ssp. secunda (Poaceae: Pooideae). Documentation of the male genitalia and dorsal habitus is provided and a diagnosis is given to distinguish the new species from similar congeners.
The austromirine plant bug genus Irianocoris is revised, with three new Australian species described: I. carvalhoi n.sp., I. carbine n.sp., and I. schuhi n.sp. The previously described Australian species, I. australicus Carvalho, is redescribed, and its distributional range extended to Western Australia. The type species, I. italae Carvalho, from Indonesia (Irian Jaya) is redescribed and recorded from Papua New Guinea for the first time. A generic redescription and a key to species are given. The diagnostic characters of the male and female genitalia are illustrated.
The new pilophorine plant bug genus Randallophorus is described to accommodate the new species R. schuhi from Paraguay. Images of the holotype male and a paratype female, illustrations of male genitalia, and a key to the New World genera of Pilophorini (Miridae: Phylinae) are provided.
The genus Coquillettia was recently revised with 14 newly described species. One of the species, C. schuhi, was dedicated to Randall T. Schuh. Of the treated species, the females of only C. alpina Wyniger and C. polhemorum Wyniger were discussed. In this paper the female of C. schuhi is described.
A new species, Hypseloecus schuhi is described from seven specimens collected on Amyema nestor (Loranthaceae) in Charles Darwin Reserve, in the Avon Wheatbelt region of Western Australia. This is the first species recorded solely from Western Australia on an endemic host plant.
Three new genera of the plant bug subfamily Phylinae are established. Each genus is described to accommodate single undescribed species found in central Thailand. Randallopsallus paracastaneae, Brendaphylus soloccidens, and Ellacapsus sensibilis are diagnosed and described. Habitus images of live individuals are provided for all species. These taxa are placed in the tribe Phylini.
The genus Hermatobates is revised and considered to contain 12 valid species, including two new species described herein: H. schuhi from the Ryukyu and Tokara Islands, and H. palmyra from the Line Islands. A morphological redescription is provided for H. djiboutensis from the Indian Ocean, and a neotype is designated for H. singaporensis from Singapore. All previous records of H. marchei from Australia are considered to instead represent H. weddi. A revised key is provided to all known species of Hermatobates, and scanning electron micrographs are provided for certain key characters of the legs, thoracic venter, and male genitalia in H. schuhi, H. palmyra, H. djiboutensis, H. weddi, H. marchei, and H. kula. Additional photographic illustrations are provided for key characters in H. haddoni, H. bredini, H. hawaiiensis, H. tiarae, H. palmyra, H. djiboutensis, H. singaporensis, H. marchei and H. armatus, and line drawing illustrations are provided for endosomal structures in H. weddi, H. haddoni, H. djiboutensis, and H. bredini. Distribution maps are also provided for all species. It is suggested that characters of the male endosomal and metasternal morphology provide an initial basis for delineation of five intraspecific species groupings. It is hypothesized that repeated episodes of vicariance related to alternating high and low Quaternary sea level stands have led to the current segregation of morphologically similar species within the H. weddi group in the region between Australia and Southeast Asia.
A new species of water scorpion, Ranatra schuhi, is described from the Shan Plateau of upper Burma. This new species is member of the Ranatra gracilis species group, but can be easily separated from previously described members of that group by the distinctive structure of the male paramere. Illustrations are provided of key characters diagnostic for R. schuhi, including the structures of the head, respiratory siphon, male forelegs and genitalia. A revised key to the species of the Ranatra gracilis group is provided, as well as additional Burmese records for Ranatra lansburyi Chen, Nieser and Ho, Ranatra libera Zettel, and Ranatra varipes Stål. The previously undescribed male of Ranatra distanti Montandon is described based on material from the Andaman Islands, and the structure of the male paramere illustrated.
The genus Aleixus McDonald is reviewed and a new species described. The genus was monotypic and known from a single female from Brazilian Amazonia. The new species Aleixus tobyschuhi described from southern Brazil, greatly extends the distribution of Aleixus. A cladistic analysis, including 30 morphological characters and 18 taxa, was performed using TNT with the implicit enumeration algorithm, with three weighting schemes: equal (EW), successive approximation (SW), and implied weighting (IW). Analysis under EW resulted in four cladograms (L = 74, CI = 60, RI = 78). Analyses under SW and IW resulted in one most parsimonious cladogram, with fit varying from 20.4 (K = 0.64) to 26.6 (K = 5.80). The cladogram obtained under differential weighting schemes is included in the set of cladograms found under EW. The monophyly of the tribe Procleticini and genus Aleixus were recovered in all analyses. Non-ambiguous synapomorphies for Aleixus include antennal segment II longer than antennal segment I, and humeral angles developed in spatular projections, dorsally bifid. Non-ambiguous synapomorphies of Procleticini are metasternum sulcate, ventral rim of pygophore with a medial U-shaped emargination and with 1 1 process with different degree of development, and gonocoxites 8 smaller than laterotergites 9. A hypothesis of relationships among Procleticini genera was possible only under IW analysis. Two main clades were recognized: clade A, including the genera Brepholoxa Van Duzee, Dendrocoris Bergroth, Procleticus Berg, and Thoreyella Spinola; and clade B, including the genera Aleixus, Odmalea Bergroth, Parodmalea Rider, and Pseudobebaeus Distant.
Labroplatys gen. nov. (Hemiptera: Heteroptera: Plataspidae), its type species L. schuhi sp. nov. (China: Yunnan) and an additional species L. khankhaak sp. nov. (Laos, India: Tamil Nadu) are described. The new genus is characterized by the greatly enlarged labrum and the posteriorly produced female terminalia.
A new species of MafulemesaWygodzinsky 1966 (Emesinae: Leistarchini) is described from Queensland, Australia. This genus differs from other Leistarchini by its unique wing venation, wherein the M vein inserts on the submarginal vein. This is the first Australian record of Mafulemesa—a genus previously known only from a single species in New Guinea.
Pronozelus schuhi gen. nov. and sp. nov. of Harpactorini is described from the eastern Colombian Andes. A dorsal habitus, photographs of male genitalia, and a key to distinguish Pronozelus from the most similar genera are provided.
Schizopteridae, the largest of the five families of Dipsocoromorpha or litter bugs, currently comprise 48 genera and ∼235 species in three subfamilies. Due to their small size (1–2 mm), cryptic habits, high diversity in the tropics, and the fact that few contemporary experts focus on the group, a significant proportion of schizopterid diversity remains undocumented. Based on one female and three male specimens, Voragocoris schuhi, n. gen. n. sp., is here described from the Andean foothills in Southeastern Peru. Specimens were collected by sweeping low vegetation and suspended leaf litter. The new taxon is placed in the subfamily Schizopterinae and belongs to the Corixidea genus group. The unique modification of the ventral surface of the male pygophore differentiates this taxon from all remaining Schizopterinae and Schizopteridae. Color images of habitus and details of the thorax and abdomen are provided together with scanning electron microscopical documentation and drawings.
Monosteira unicostata is reported as established in British Columbia, and thus is a new alien species in North America. It has also been intercepted in Ontario on imported grapes. A description of M. unicostata and a key to the genera of Tingidae in Canada are provided to help distinguish this adventive species from other Canadian Tingidae. This brings the total adventitive Tingidae in this country to six.
