Neurepidosis emarginata sp. nov. Figs 16–19 Diagnosis. Neurepidosis emarginata differs from the congeneric species in that a long, dorsal portion of the eye bridge is devoid of ommatidia; the necks of the medial flagellomeres are shorter than the nodes; the palpus has almost invariably only three segments; and the empodia are same length as the claws. As for genitalic characters, in no other Neurepidosis is the gonocoxal emargination so wide and deep (Fig. 19, ↓ 5). The conspicuously thin ejaculatory apodeme (↓ 6) of N. emarginata resembles that of N. decorata Jaschhof, 2013, a species with otherwise completely different genitalic structures (Jaschhof & Jaschhof 2013: fig. 67B). Females and larvae of N. emarginata remain unknown. Other male characters. Body size 1.3 mm. Head. Neck of fourth flagellomere 0.7 times the length of node; circumfila with 1–2 short posterior extensions (Fig. 18). Palpus usually with 3 segments, the third being the longest; one specimen with 4 segments is considered a rare exception. Wing 3.1 times longer than wide. Genitalia. Posterior edge of ninth tergite broadly rounded, with inconspicuous, T-shaped sclerotization medially (Fig. 16). Gonocoxae: ventral bridge conspicuously short, with pigmented band below the emargination; dorsoposterior portions elongated into rounded lobes (Fig. 19). Gonostylus convex, bent; apex pointed, which in some specimens (Fig. 17) is more pronounced than in others (Fig. 19), depending on preparation. Tegmen robust, clearly tapered towards apex, lateral edges reinforced, apex slightly incised (Fig. 19). Etymology. The species name, emarginata, Latin for emarginate, refers to the gonocoxal emargination whose considerable size is characteristic of this species. Type material. Holotype.
