Benoibates crinitus (Berlese 1910) is redescribed from the USA, based on the topotypes.     

Two new species of the family Suctobelbidae (Acari,Oribatida) from Chile

Two new species of the oribatid mite family Suctobelbidae (Acari, Oribatida) are described from southern Chile. Niosuctobelba sphagnicola Ermilov, sp. n. differs from N. ruga Chinone, 2003 in the rostrum with a median incision and one pair of lateral teeth, the heads of bothridial setae rounded distally, the tectopedial fields not fused anteriorly, the notogastral setae barbed, and the body without striate ornamentation. Zeasuctobelba tierradelfuegoensis Ermilov, sp. n. differs from Z. trinodosa Hammer 1966 in a shorter body, the heads of the bothridial setae with thin apices, the tectopedial fields not fused anteriorly, and the notogastral humeral tubercles with longer cristae. An identification key to the known species of Zeasuctobelba is given. The genus Niosuctobelba is recorded for the Neotropical Region for the first time, while Zeasuctobelba is new to the fauna of Chile.

Descriptions of two new species of feather mites (Acarina: Psoroptidia: Pteronyssidae) from Ivory Coast

Two new feather mite species of the family Pteronyssidae Oudemans, 1941 collected from birds captured in Ivory Coast are described: Pteronyssoides cyanomitrae n. sp. from Cyanomitra obscura (Jardine) (Passeriformes: Nectariniidae) and Conomerus pygmaeus n. sp. from Hylia prasina (Cassin) (Passeriformes: Macrosphenidae). Pteronyssoides cyanomitrae n. sp. belongs to the nectariniae species group and differs from the closest species, P. garioui Gaud & Mouchet, 1959, in having, in males, the adanal shield present and setae f longer than setae d on the tarsus III; females of this species have the hysteronotal shield with two small median incisions on the anterior margin barely extending beyond the level of setae e2. Conomerus pygmaeus n. sp. is the first species of this genus found on a passerine host, and seems to be more similar to C. sclerosternus Gaud, 1990. This new species has the following distinctive characters: in females, the opisthosoma has small lobe-like extensions and the central sclerite is fused posteriorly with the lateral opisthosomal sclerites; in males, coxal fields I–IV lack large sclerotised areas.     

New species of the bristletail families Ateluridae and Lepismatidae (Zygentoma) from Abkhazia and Adygea

Four new species of the bristletail families Ateluridae (Atelura abkhazica sp. n. and Nipponatelurina caucasica sp. n.) and Lepismatidae (Lepisma xylophila sp. n. and L. adygei sp. n.) are described. Atelura abkhazica sp. n. differs from the other species of the genus Atelura in a smaller size, smaller number of ovipositor divisions, in the presence of apical sensory cones on the male parameres, which are absent in the other species of the genus, and in a fewer number of lateral pegs on urotergite X. The genus Nipponatelurina comprises two species (N. kurosai Mendes et Machida, 1994 and N. caucasica sp. n.). The distinguishing features of N. caucasica sp. n. include a significant number of short minute thin cilia on the head capsule, a longer ultimate segment of the maxillary palp, and a fewer number of setae at the posterior margin of urosternites IV–VII. Lepisma xylophila sp. n. differs from L. saccharinum and L. chlorosoma in the distribution of epidermic pigment and in the urotergites chaetom. Lepisma adygei sp. n. is most closely related to the synanthropic species L. saccharinum, but differs in the size of the body, color of scales on the upper surface of the body, and in the structure of the labial palps, urotergite X, ovipositor, and parameres.

A new species Nothrus xuejianensis Ermilov sp. n. is described; it differs from the closest species, Nothrus meakanensis Fujikawa, 1999 by the morphology and length of notogastral setae h₂ and number of subcapitular setae m.     

New species of chalcidoid wasps of the family Eurytomidae (Hymenoptera,Chalcidoidea) from arid Palaearctic regions

Five new species of chalcidoid wasps of the family Eurytomidae are described: four from Israel and one from Kazakhstan. Tetramesa pavliceki Zerova, sp. n. (cylindrica species group) is closely related to T. scheppugi Schlecht., but differs in the more elongate flagellar segments, longer genae, and smooth metasomal tergites. Eurytoma nevoi Zerova, sp. n. is similar to E. sabulosa Erd. and E. bicolorata Zer. (phragmiticola species group), differs from these species in the longer marginal vein, punctate propodeum, and longer flagellar segments. E. oreni Zerova, sp. n. belongs to the fumipennis species group. It is closely related to E. monticola Zer., but differs in the more convex scape, longer postmarginal vein, and yellow legs. E. simutniki Zerova, sp. n. belongs to the robusta species-group. It resembles E. heriadi Zer., but differs in the longer flagellar segments of the female and in the shorter postmarginal vein. Nikanoria mamayevi Zerova, sp. n. is similar to N. stigma Zer., but differs in the more elongate metasoma, longer flagellar segments of both sexes, and larger yellow spots on the pronotum.     

New scarab-beetle species (Coleoptera,Scarabaeidae, Aphodiinae,Orphninae) from Central Asia and Southern Africa

Three new scarab-beetle species are described. Aphodius moronensis sp. n. (northern Mongolia) and A. kozlovi sp. n (eastern Tibet) with modified spurs on fore tibiae in males are placed in the falcispinis group of the subgenus Agolius but are similar to the grafi group of the subgenus Chilothorax in the shape of parameres and elytral pattern. The new species differ from A. falcispinis in the shape of the spur; A. moronensis sp. n. also differs in the shape of the body and parameres. Orphnus transvaalensis sp. n. is the second apterous Orphnus species found in Southern Africa. It differs from the closely related O. harrisoni in the shape of parameres, position of the hornlike clypeal process, and in a smaller body size.     

New species of the bristletail genus <Emphasis Type="Italic">Allopsontus</Emphasis> Silv. (Microcoryphia,Machilidae) from Southeastern Kazakhstan and Abkhazia

Two new bristletail species, Allopsontus (Anisoptinus) nigrus sp. n. from Southeastern Kazakhstan and A. (Kaplinilis) abkhazicus sp. n. from Abkhazia, are described. A. nigrus sp. n. differs from the only other known species of the subgenus Anisoptinus, A. borgustani Kaplin 2015, in a number of characters, namely, in more rounded paired ocelli, an extended apical segment of the labial palpus, a long articulated ovipositor, and in the absence of short appressed pigmented setulae on the maxillary and labial palpi in males. A. abkhazicus sp. n. can be easily distinguished from all the other known species of the subgenus Kaplinilis by the absence of short appressed pigmented setulae on the maxillary and labial palpi in the males, the absence of a projection with numerous spiniform setae on the male fore femur, and in shorter male genital appendages. The ocellus of the male and female is 2.8-2.9 times as wide as long; the length to width ratio of the eye is 0.9-1.0; the ovipositor consists of 60 divisions.     

Free-living nematodes of the genus <Emphasis Type="Italic">Alaimella</Emphasis> Cobb 1920 (Nematoda: Leptolaimidae): A description of <Emphasis Type="Italic">A. macramphis</Emphasis> sp. n. from the White Sea and a revision of the genus

Alaimella cincta Cobb 1920 and Alaimella macramphis sp. n. are described and illustrated. Both the species were first recorded for the White Sea in northern Russia. A. cincta occurs in the shells of the agglutinated foraminiferan Reophax curtus, as well as freely in bottom sediments. A. macramphis sp. n. is described from a single male sampled from bottom sediments. A. macramphis sp. n. is distinguished from two previously known species of Alaimella (A. cincta Cobb 1920 and A. truncate Cobb 1920) by having a longer body, longer cephalic setae, and a wide amphid equal to the respective body diameter. The new species also differs from A. truncate by the distinct striation of the cuticular annulations. The Alaimella species are additionally characterized by having a posterior glandular widening of the esophagus. An emended diagnosis of the genus Alaimella Cobb 1920 and a key for species identification are provided.     

Composition of the genera <Emphasis Type="Italic">Gnaptorina</Emphasis> Reitter and <Emphasis Type="Italic">Pseudognaptorina</Emphasis> Kaszab of the tribe Blaptini (Coleoptera,Tenebrionidae)

Based on the structure of the segments of the male fore and middle tarsi, three subgenera are distinguished in the genus Gnaptorina Reitter: Gnaptorina s. str. (brushes or tufts of pale setae are present on the sole surface of the 1st–3rd segments of the fore tarsus and also on the 1st and 2nd segments of the middle tarsus, the type species Gnaptorina felicitana Reitter, 1887), Boreoptorina subgen. n. (a brush is present on the sole surface of the 1st segment of the fore tarsus, but is absent on the sole surface of the segments of middle tarsus, the inner margin of the male fore tibia with a hairy brush, the type species Gnaptorina cordicollis G. Medvedev, 1998), and Hesperoptorina subgen. n. (a flat hairy brush is present only on the sole surface of the 1st segment of the fore tarsus, type species Gnaptorina brucei Blair, 1923). The genus Pseudognaptorina Kaszab, 1977 is considered monotypical. Lectotypes of four species of Gnaptorina are designated.     

New species of the Lithobiid genus <Emphasis Type="Italic">Hessebius</Emphasis> Verhoeff, 1941 (Lithobiomorpha,Lithobiidae) from Eastern Kazakhstan

Two new species, Hessebius golovatchi Farzalieva, sp. n. and Hessebius zalesskajae Farzalieva, sp. n., are described based on material from the Dzungarian Alatau Mountains, Eastern Kazakhstan. The female of H. golovatchi sp. n. differs from all the previously known species of the genus in the presence of 3 + 3 spurs on the gonopod, while H. zalesskajae sp. n. is similar to H. perelae Zalesskaja, 1978 but differs in some structural details of the male and female gonopods.
