Neoquintius aracelianus new species, from Ecuador and Stentoquintius hasselinus new species, from Venezuela are described in the tribe Nematopodini (Coreidae); both are compared with the related species. Dorsal habitus photos, and drawings of male genital capsule are included. Keys to the known species of each genera are included.
Aulacus canlaon, new species, is described from Negros Island, Philippines. The species is illustrated and separated from the other three species of Aulacus known from the Oriental Region. It is the second species of Aulacus recorded from the Philippines.
Series of Perreyiella from Mexico and French Guiana resolve association of sexes and extent of color variation for two species. Perreyiella godmani (Cameron 1883), n. comb. (= Perreyiella mexicanaSmith 1990, n. syn.), occurs from southern Mexico to Costa Rica. The female and male are described, and color variation from entirely black to partly red is noted. Perreyiella lacourtiSmith, 1990, is known from French Guiana, and the female and male are described.
A new species, Tagalis drakkar n. sp., is described from Misiones, Argentina. It is easily separated from the other species of the genus by the particular shape of the median process of the pygophore and other male genitalic structures, and the overall pale coloration. We also describe the male aedeagus of Tagalis femorata Melo (2008) and discuss the affinities of the two species studied in the context of species groups proposed by Castro-Huertas and Forero (2014).
Carpilis barberi (Blatchley), Ptochiomera nodosa Say, Sisamnes claviger (Uhler), and S. contractus Distant are related seed bugs of the lygaeoid family Rhyparochromidae that once were placed in the same genus (Ptochiomera). The habits of only P. nodosa are well known. All four species (only one specimen of S. claviger was observed) were associated with the large, dense crowns of weeping lovegrass (Eragrostis curvula; Poaceae), an African bunchgrass that has been planted extensively in the southern United States. All species (excepting S. claviger) also were collected from crowns of native grasses of bunched growth habit; C. barberi also was associated with plants of other graminoid families: Cyperaceae (sedges) and Juncaceae (rushes). Arkansas, Georgia, Oklahoma, and South Carolina are new state records for C. barberi; Arkansas for P. nodosa and S. claviger; and Arkansas and Oklahoma for S. contractus. The three more frequently collected myodochines overwintered in crowns of weeping lovegrass (and other graminoids), where they would be protected from extremes in temperatures and have access to seeds of graminoids and other plants. Carpilis barberi, S. claviger, and S. contractus can be added to the infrequently collected North American insects that have colonized the African E. curvula. Although considered invasive in certain regions of the world where it has been introduced, weeping lovegrass may help conserve native insect diversity in the southern United States.
The South American moth Porphyrosela minuta Clarke (Gracillariidae) is documented for the first time in the United States, where it is already widespread. The larvae are leafminers of white clover (Trifolium repens L., Fabaceae). Adults and larval habits are compared with those of the native Nearctic P. desmodiella (Clemens), which mines leaves of several other legumes.We summarize and add to the known distribution and parasitoid records for both species.
The genus Stridulivelia Hungerford (Heteroptera: Veliidae: Veliinae) is composed by 15 species, which are divided into the subgenera Stridulivelia s.str. Hungerford and Aenictovelia Polhemus. The nominal subgenus includes ten species restricted to South America, ranging from Colombia to Argentina. The other subgenus contains five primarily Mesoamerican species, one of which extends its distribution into northern South America. An updated identification key, diagnoses, notes, and illustrations of all South American species are provided.
We describe three new species of Rectiostoma Becker, 1982 from northwestern Costa Rica: R. annemayae Heikkilä and Metz, n. sp., R. eowilsoni Heikkilä and Metz, n. sp., and R. philipmayi Heikkilä and Metz, n. sp. We used a data set of DNA barcodes (cytochrome oxidase I) accumulated for Lepidoptera collected at Area de Conservación Guanacaste (ACG) to initially delimit the species, then we confirmed identities with morphology of the male and female genitalia. We provide a neighbor-joining tree with supporting statistics, illustrations of adult specimens and their genitalia, and the first host plant records for Neotropical Rectiostoma species. We also include photographs of the larvae of R. annemayae and R. eowilsoni.
A new species of the phyline plant bug genus Rubrocuneocoris Schuh (Hetereroptera: Miridae) is described from Hawaii. Although known only from the Oahu and Hawaii in the Hawaiian Islands, it is considered an adventive species originating from elsewhere in eastern Asia or the Indo-Pacific Region. A diagnosis, description, habitus images, and illustrations of male genitalia are provided to help distinguish this new species from the other 13 previously known species of the genus.
The genus Monocellicampa is reviewed. A diagnosis of the genus and the differences between Monocellicampa and Hoplocampa are discussed. Monocellicampa yangae Wei, n. sp., as a pest of Prunus salicina, is described from China. Monocellicampa pruniWei, 1998 is redescribed and the male of the species is described for the first time.
AnochetusMayr, 1861 is revised for the Arabian Peninsula based on the worker caste. Three species are recognized, Anochetus annetteae n. sp., A. sedillotiEmery, 1884, and A. traegaordhiMayr, 1904. Anochetus annetteae n. sp. is described from Hibra Village, the Nakhl Region, Sultanate of Oman, based on the worker caste. An illustrated key to the Arabian species of Anochetus is given, including a distribution map for the three Arabian species. New distribution records for A. traegaordhi for the Kingdom of Saudi Arabia are also presented.
The genus Ecdytolopha Zeller, 1875 includes 14 described species whose geographic distributions encompass most of temperate North America and a large part of the northern Neotropics. Two new species are described: Ecdytolopha nigrita Brown, new species, from southeastern Arizona, U.S.A.; and Ecdytolopha meridana Brown, new species, from Merida, Venezuela. A neighbor-joining tree based on COI sequences of Ecdytolopha insiticiana Zeller, E. mana (Kearfott), E. occidentana Adamski and Brown, E. nigrita, and E. fabivora (Meyrick) is presented. Although percent divergence within species is typical for Lepidoptera, divergences between species of Ecdytolopha are fairly large, with the most similar pair (i.e., E. insiticiana and E. mana) 9.1% different.
Two hundred and sixty-two adventive aphids (Hemiptera: Aphidoidea) have been previously reported in North America north of Mexico. We update this to include 25 previously unrecorded species, and include information on the location and date of first discovery, biogeographic origin, and economically important North American hosts for these species. The number of adventive species introduced per year has decreased overall since 1930.We discuss aphids intercepted at United States ports of entry and identified by the Systematic Entomology Laboratory from 2000–2016 and comment on how the composition of species intercepted may affect the adventive species that become established.
