Reevaluation of the odd chrysidid genus Atoposega Krombein (Hymenoptera,Chrysididae, Amiseginae)

The south Asian amisegine genus Atoposega Krombein, 1957, is reevaluated.

Nacerdes (Xanthochroa) arcuata sp. n. is a new species belonging to carniolica group. The species were collected from Anhui (Eastern China, 30°02''17.37"N, 118°50''1.72"E). A key to the species of the species-group from China is given along with a distribution map.     

Perlesta ephelida, a new Nearctic stonefly species (Plecoptera, Perlidae)

A new Nearctic species of Perlidae (Insecta, Plecoptera), Perlesta ephelidasp. n., is described from the male, female, and egg stages. This species has been previously reported as, or confused with, Perlesta shubuta Stark from several central and eastern U.S. states. Perlesta ephelida is distinctive from Perlesta shubuta and other regional Nearctic congeners mainly according to male genitalic and egg characteristics. Perlesta ephelida is a widely-distributed eastern Nearctic species, whereas Perlesta shubuta appears to be restricted to a narrow latitudinal belt in the Gulf Coast region from Louisiana east conservatively to the Florida panhandle. The egg of Perlesta shubuta is depicted with scanning electron microscopy for the first time.

Andinopanurgus, a new Andean subgenus of Protandrena (Hymenoptera, Andrenidae)

A new subgenus of Protandrena Cockerell (Panurginae: Protandrenini) from South America, Andinopanurgus Gonzalez & Engel, subgen. n., is described and figured for distinctive species of the genus occurring at mid- and high elevations in the Andes from Venezuela to Peru (1100-3400 m). In addition to the distribution, the subgenus is easily distinguished from other subgenera by a unique combination of morphological characters in both sexes, especially in the hidden sterna and genitalia of the male. Protandrena amyaesp. n., and Protandrena femoralissp. n., are also described and figured from the Ecuadorian and Peruvian Andes. New geographical records and a key to the species are also provided.

Molecular phylogeny of the Trechus brucki group, with description of two new species from the Pyreneo-Cantabrian area (France, Spain) (Coleoptera, Carabidae, Trechinae)

A molecular phylogeny of the species from the Trechus brucki clade (previously Trechus uhagoni group)based on fragments of four mitochondrial genes and one nuclear gene is given. We describe Trechus (Trechus) bouillonisp. n. from the western pre-Pyrenees: Sierras de Urbasa-Andía, Navarra, Spain. The species was collected in mesovoid shallow substratum (mss), a subterranean environment. Molecular as well as morphological evidences demonstrate that the new species belongs to the Trechus brucki clade. A narrow endemic species of high altitude in western French Pyrenees merged with Trechus brucki Fairmaire, 1862a, Trechus bruckoidessp. n., is described. A lectotype is designated for Trechus brucki and Trechus planiusculus Fairmaire, 1862b (junior synonym of Trechus brucki). The species group is redefined based on molecular and morphological characters, and renamed as the brucki group, as Trechus brucki was the first described species of the clade. A unique synapomorphy of the male genitalia, a characteristic secondary sclerotization of the sperm duct, which is shared by all the species of the brucki group sensu novo, is described and illustrated. The Trechus brucki group sensu novo is composed of Trechus beusti (Schaufuss, 1863), Trechus bouillonisp. n., Trechus brucki, Trechus bruckoidessp. n., Trechus grenieri Pandellé, 1867, T. uhagoni uhagoni Crotch, 1869, T. uhagoni ruteri Colas, 1935 and Trechus pieltaini Jeannel, 1920. We discuss the taxonomy of the group and provide illustrations of structures showing the differences between the species, along with distribution data and biogeographical comments.

Sinocorophium hangangense sp. n. (Crustacea, Amphipoda, Corophiidae), a new species from Korea, with a key to the genus Sinocorophium

A new species of the corophiid gammaridean amphipod belonging to the genus Sinocorophium Bousfield & Hoover was collected from the lower reaches of the Han River in Gyeonggi-do, Korea. A relatively large body size and morphology of the uropods 1 and 3 are the major characteristics which serve to distinguish the new species from its congeners. The new species is fully illustrated and extensively compared with related species. A key to the species of (Sinocorophium is also provided.
