The cleptoparasitic bee genus Triepeolus Robertson, 1901 (Hymenoptera: Apidae) is revised for species occurring in South America. A total of nine species are confirmed from the continent, of which T. tuberculifer Onuferko, Rightmyer & Roig-Alsina sp. nov. is newly described. Four new synonymies are proposed: T. aguilari Moure, 1955 syn. nov. and T. megadelphus Cockerell, 1914 syn. nov. under T. buchwaldi (Friese, 1908); T. bilineatus Cockerell, 1949 syn. nov. under T. flavipennis (Friese, 1916); and Epeolus merus Brèthes, 1909 syn. nov. under T. nemoralis (Holmberg, 1886). Males of T. alvarengai Moure, 1955 and T. rufotegularis (Ashmead, 1900) and females of T. atoconganus Moure, 1955 and T. cecilyae Packer, 2016 are described for the first time. Lectotypes are designated for the following (all originally described under Epeolus Latreille, 1802 but now recognized as Triepeolus): E. buchwaldi, E. flavipennis, E. osiriformis Schrottky, 1910 and its junior synonym E. luteipes Friese, 1916, and E. rufotegularis. Diagnoses and complete descriptions/redescriptions are provided for all species, along with a fully illustrated dichotomous identification key (with Portuguese and Spanish versions available as supplementary material) to distinguish them based on external morphological features. Additionally, known collection records and information about the ecology of the treated species are presented.
Three new species of pseudoscorpion, Allochthonius lini sp. nov. (Xiaoguoquan Cave) and Selachochthonius yinae sp. nov. (Xiao Cave) from Yunnan Province, Allochthonius xuae sp. nov. (Yelaoda Cave) from Guizhou Province, are described and illustrated. An identification key is provided for all known Chinese representatives of the family Pseudotyrannochthoniidae.
A new species of Laubierpholoe Pettibone, 1992 (Annelida, Sigalionidae), Laubierpholoe massiliana Zhadan sp. nov., was found in two submarine caves near Marseille (France). This is the first record of the genus in the Mediterranean Sea. The new species differs from congeners by inhabiting soft sediments instead of having an interstitial lifestyle and by several morphological characters: the ventral tentacular cirri slightly shorter or of similar length to the dorsal tentacular cirri, the presence of bidentate neurochaetae, the body length, and the number of segments. Molecular phylogenetic analysis using 18S rRNA and 28S rRNA sequences confirmed that the new species belongs to the genus Laubierpholoe, as well as the monophyly of the genus. The ecology of the new species and its adaptation to the cave-dwelling lifestyle are discussed. An identification key for all known species of Laubierpholoe is provided.
Ten new species of Thinophilus Wahlberg, 1844 from the Afrotropical region are described and illustrated: T. saegeri sp. nov. from the Democratic Republic of the Congo, T. medvedevi sp. nov., T. longicercus sp. nov., T. cataractae sp. nov. and T. manambato sp. nov. from Madagascar, T. gallagheri sp. nov. and T. deemingi sp. nov. from Oman, T. sigwalti sp. nov. from Senegal, T. subpalpatus sp. nov. from South Africa, and T. fluvialis sp. nov. from Tanzania. Type material for 13 previously described Afrotropical species is examined. The genus Paralleloneurum Becker, 1902 is newly synonymized with Thinophilus (syn. nov.). As a result, the following new combinations are here established: Thinophilus cilifemoratus (Becker, 1902) comb. nov. and T. pygmaeus (De Meijere, 1916), comb. nov. The following new synonyms are proposed: Thinophilus annulitarsis Parent, 1936 with T. calopus Loew 1852; T. bipunctatus Curran, 1926 and T. maculatus Parent, 1929 with T. indigenus Becker, 1902. New records are given for some known species. Thinophilus argyropalpis Becker, 1910 and T. spinitarsis Becker, 1907 are reported from the Afrotropical Region for the first time. The number of species of the genus, known from continental Africa, Oman, Yemen and Madagascar, has increased to 30. An identification key to 29 Afrotropical species is compiled. Thinophilus versutus Haliday, 1851 and T. cilifemoratus (Becker, 1902), type species of the former genera Schoenophilus Mik, 1878 and Paralleloneurum Becker, 1902, are subsequently also included into the key, because the two species inhabit northern Africa.
Coilodes Westwood, 1846 is a Neotropical genus of Hybosorinae. Despite being a morphologically homogeneous genus, it presents a great deal of intraspecific variation, especially with reference to the colour of integuments. This makes identification of species even more difficult, since the majority of original descriptions present the colour as the main diagnostic character. To solve this problem, the first taxonomic revision of Coilodes is presented. The genus now comprises 13 species. Redescriptions of C. castaneus Westwood, 1846, C. fumipennis Arrow, 1909, C. humeralis (Mannerheim, 1829), C. niger (Mannerheim, 1829), C. ovalis Robinson, 1948, C. parvulus Westwood, 1846, and C. punctipennis Arrow, 1909 are presented. Coilodes niger (Mannerheim, 1829) has its status revalidated and three new synonyms are proposed: C. gibbus (Perty, 1830) and C. chilensis Westwood, 1846 with C. humeralis, and C. nigripennis Arrow, 1903 with C. castaneus. Biological and geographical distribution data are expanded. Lectotypes are designated for C. humeralis and C. niger. Six new species are described: C. bezerrai Basílio & Vaz-de-Mello sp. nov., C. edeiltae Basílio & Vaz-de-Mello sp. nov., C. lunae Basílio & Vaz-de-Mello sp. nov., C. mayae Basílio & Vaz-de-Mello sp. nov., C. ravii Basílio & Vaz-de-Mello sp. nov., and C. skelleyi Basílio & Vaz-de-Mello sp. nov. An identification key for the males of the species is presented.
A new species of Epeolus Latreille, 1802 (Hymenoptera: Apidae)—E. emiliae Onuferko and Sheffield, new species—is described from North America west of the Great Plains. It is morphologically most similar to Epeolus autumnalis Robertson, 1902, a species known exclusively from east of the Rocky Mountains. DNA barcode sequences from representatives of E. autumnalis and E. emiliae share a barcode index number (i.e., BIN: BOLD:AAF2361), but the two species exhibit marked and consistent differences in integument coloration and the patterns of pubescence on the metasoma, and their distributional ranges, based on known specimens, show no overlap. This discovery increases the number of species of Epeolus confirmed in Canada to 14, and North America north of Mexico to 44. Modifications to existing identification keys to Canadian and all North American species of Epeolus are provided, as well as a differential diagnosis, to enable the identification of E. emiliae. Additionally, three new provincial records are reported for species of Epeolus occurring in Canada: E. interruptus Robertson, 1900 from Alberta and Quebec and E. scutellaris Say, 1824 from Saskatchewan.

We describe three new species of the genus Coletinia Wygodzinsky, 1980, the most diverse of the family Nicoletiidae (order Zygentoma = Thysanura s. str.) in Europe: C. dalmatica Molero-Baltanás, Fišer, Bach de Roca & Gaju-Ricart sp. nov. from Croatia, C. dextra Molero-Baltanás, Bach de Roca & Gaju-Ricart sp. nov. from Spain and C. serrata Mendes, Molero-Baltanás, Bach de Roca & Gaju-Ricart sp. nov. from Portugal. Coletinia dalmatica sp. nov. seems to be related with C. maggi (Grassi, 1887) and both Iberian species belong to the asymetrica species group. New material of some previously recognized species (C. diania Molero, Bach & Gaju, 2013, C. intermedia Molero, Bach & Gaju, 2013, C. mendesi Wygodzinsky, 1980, C. redetecta Molero, Bach & Gaju, 2013 and C. tinauti Molero-Baltanás, Gaju-Ricart & Bach de Roca, 1997) is reported, enlarging in most cases their geographic distribution, and including some new data on their intraspecific variability. Finally, an updated identification key to all known species of the genus Coletinia is given.
Species of the genus Aphelopus Dalman (Hymenoptera, Dryinidae) are important natural enemies of leafhoppers. The genus is relatively diverse in China, with 35 recorded species. In order to further make use of these important parasitoids in biological control programs, species of Aphelopus collected across China are studied using an integrative approach (combined DNA barcoding and morphology). Of the 17 studied species, two are newly recorded from China: A. nivealis Mita & Olmi, 2014 and A. prolatus Mita & Olmi, 2014, and four are described as new to science: A. incognitus Chen, Olmi & Guglielmino sp. nov., A. maculiala Olmi, Chen & Ødegaard sp. nov., A. taianensis Olmi, Ødegaard & Chen sp. nov., and A. zaifui Olmi, Chen & Liu sp. nov. The total number of Aphelopus species known from China is raised from 35 to 39. Keys to the Oriental and Eastern Palaearctic species of Aphelopus are modified to include the new species. Application of DNA barcoding in the species delimitation of Dryinidae is discussed.
A new polynoid, Webbnesia maculata gen. et sp. nov., was discovered during benthic surveys conducted around the Canary Islands. Its generic characters (absence of cephalic peaks, ventrally inserted lateral antennae, reduced notopodium and chaetae all stout) place it close to Antinoe Kinberg, 1856, Hermadion Kinberg, 1856 and Malmgrenia McIntosh, 1874, but the combination is unique and justifies the erection of a new genus. The new genus and species are described, figured and discussed in detail. An updated list of taxa and an identification key to all genera of Polynoinae Kinberg, 1856 sensu lato currently reported from the extended Northeast Atlantic are given.
A new species of verrucid barnacle, Gibbosaverruca weijiai sp. nov., is described and illustrated based on specimens collected from a deep-sea seamount, Weijia Guyot, in the West Pacific. This is the third barnacle species reported from Weijia Guyot. The new species is distinguished from its congeners by its extremely long caudal appendage. In terms of shell morphology, G. weijiai sp. nov. is most similar to G. gibbosa and G. sulcata but differs from them by the intermediate articular ridges of its movable tergum and scutum, which are distinctly wider than the axial ridges. The COI and 16S rRNA sequences of the holotype of G. weijiai sp. nov. are presented to support future research, and a key to extant species of the genus Gibbosaverruca Young, 2002 is provided.
