Differential diagnosis . Among species of complex B, the new species is very close to Harpyrhynchoides aegolius Bochkov and OConnor, 2013 ( Figs. 44 G, 45J–M). In both sexes of these species, scales or verrucosities are absent on the ventral idiosomal surface, genua I and II bear three setae each, and femora I and II bear two setae each, and the basal segment of legs III bears a single seta; in females, the apical segment of leg IV bears four setae, and palpal seta dG is relatively short and thicker than other palpalae, setae h1 and h2 are subequal in length, solenidion ω 1 I is strongly thickened, the idiosoma ventrally has a nonstriated median area bearing setae 3a , and the apical segment of leg IV bears three setae. These species differ from each other by the following character states. In females of Harpyrhynchoides athene sp. nov . , the idiosoma ventrally is non-striated between the level of setal bases 3a and the pocket-like vulvar structure (vs. striated in H. aegolius ); in males, the body is 265–275 long (vs. 310–320 long), setae g2 are situated equidistantly from g1 and g3 (vs. 1.5 times close to g1 than to g3 ), distance g2–g2 is longer than g1–g2 (vs. slightly shorter), genital setae are 11–12 long (vs. 18–20 long).
