Doryctobracon maculatus Marinho, a new species of Braconidae (Opiinae) collected in the municipalities of Piracicaba and São Roque, state of São Paulo, Brazil, is described and illustrated. This new species is placed in group of species with areolate propodeum, but is easily distinguished from other species of this group, and other members of the genus by the noticeable black to dark-brown spots on the head, mesosoma and metasoma. This new species was reared in larvae of Anastrepha pseudoparallela (Diptera, Tephritidae) in passion fruits, Passiflora alata Curtis (Passifloraceae). An illustrated key to species of Doryctobracon recorded in Brazil is presented.An integrative taxonomic analysis of Hierodula patellifera (Audinet-Serville) is presented based on morphological and molecular characters (COI, 28S rDNA). During repeated trips to the Korean peninsula, we collected unusual specimens from Wanju-gun. They were similar to H. patellifera, but can be distinguished by a larger body size, the number and shape of spines on foreleg, and the shape of male genitalia. To examine the phenotypes and delimit H. patellifera from fourteen sampled populations, we used forecoxal spines and male genitalia as key morphological characters, as well as molecular data including gene tree monophyly and genetic divergence data. The molecular analyses (p-distance, neighbor-joining, and parsimony analyses) did not separate the specimens as two distinct species. The diagnostic characters of H. patellifera are illustrated with habitus images.Two new species of the genus Broscosoma Rosenhauer, 1846 are described from China Broscosoma guoliangi sp. nov. from Fujian Province and Broscosoma qiului sp. nov. from Chongqing City, respectively. In addition, Broscosoma ribbei rougeriei Deuve Tian, 2002 is newly recorded from Derung-Nu Autonomous County Gongshan, Yunnan Province, China.Horaeomorphus Schaufuss is an easily identifiable genus of Stenichnini, predominantly distributed in the Australasian realm. Many scydmaenines occurring in other regions, however, have been misplaced in Horaeomorphus, and therefore the true distribution of this genus remains unclear. In previous studies several new genera were established for Australian species misplaced in Horaeomorphus, and a few species misplaced in Euconnus Thomson, Stenichnus Thomson, and Syndicus Motschulsky were transferred to Horaeomorphus. Three species that inhabit New Caledonia were placed in this genus Horaeomorphus australis Franz, H. baloghi Franz, and H. novaecaledoniae Franz. Examination of these taxa revealed that none of them was conspecific with the SE Asian type species of Horaeomorphus. Three new combinations are proposed Heterotetramelus (s. str.) australis (Franz) comb. n., Heterotetramelus (s. str.) baloghi (Franz) comb. n., and Heterotetramelus (s. str.) novaecaledoniae (Franz) comb. n.; each species is redescribed.Two new species of calanoid copepods are described; Metacalanus adriaticus sp. nov. from an anchialine cave on Vis Island, and Paramisophria tvrtkovici sp. nov. from Orljak Cave, located in the lower part of River Krka estuary, near the town of Šibenik (Croatia). This is the first report of arietellid copepods found in any anchialine cave along the coast of the Adriatic Sea. In M. adriaticus sp. nov. the antennules are asymmetrical in both sexes (the female left antennule is 18-segmented, right 20-segmented; male left 16-segmented and right 20-segmented); the uniramous fifth legs of the female are 2-segmented; the terminal segment of the fifth leg in both sexes is the longest; and in the male the fifth leg exopod is 2-segmented. In P. tvrtkovici sp. nov. the antennules of both sexes are asymmetrical with the left antennule longer than the right, the female antennule is 21-segmented on both sides; the male left antennule is 19-segmented, the right 21-segmented; the armature of the terminal exopod segment of leg 1 is II, 2 ,2; the male fifth legs have a rudimentary endopod on the left leg, the third exopodal segment is smallest and bears three unequal processes on its outer margin, and the terminal spine is completely separated from the segment. On the right leg the third segment carries two short, unequal processes on its outer distal margin, as well as a long sigmoidal spine which is fused to the segment. It is inferred that, after the last glaciation, these new Arietellids moved out from their southern Adriatic refuge, colonizing first the anchialine habitats of the outer eastern Adriatic islands and then spreading along the coast.This paper is primarily a compilation of published data on the staphylinid beetle species reported for El Salvador. It is based on taxonomic and ecological literature, with inclusion of some new records from different entomological collections. Thirty eight genera and 96 species are reported in the list, including a first country record Eulissus chalybaeus. Country-level distribution outside of El Salvador, locality references and topographic zones are included for each species. In the list, three endemic species are recorded Seeversiella badia, S.  https://www.selleckchem.com/products/vorapaxar.html  minima and Stenus salvadorensis. It is remarkable that 14 genera (37%) and 52 species (54%) have only been reported at a country level in the literature, without a specific locality of collection, indicating the need for local inventories of this coleopteran family in the salvadoran territory.Four new species of Raphidiidae are described from the early Eocene of western North America Megaraphidia antiquissima sp. nov. from McAbee, M. ootsa sp. nov. from Driftwood Canyon, M. hopkinsi sp. nov. from the Allenby Formation (all from British Columbia, Canada), M. klondika sp. nov. from Republic (Washington, United States of America). Archiinocellia Handlirsch, 1910, Archiinocellia oligoneura Handlirsch, 1910 from Horsefly River (British Columbia, Canada), and A. protomaculata (Engel, 2011), comb. nov., from the Green River Formation (Colorado, United States of America) are redescribed. Archiinocellia is assigned to Raphidiidae, sit. nov. The apparent absence of sclerotized gonocoxites 9 in the Archiinocellia protomaculata male is probably plesiomorphic at the family level. As some modern snakeflies do not require a cold interval to complete their development and Eocene Inocelliidae and Raphidiidae lived in regions of warm winters (especially A. protomaculata), adaptation to cold winters in many modern snakeflies is a post-Eocene phenomenon.
