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.
