Summary: | Neurepidosis hybrida sp. nov. Figs 20–21 Diagnosis. Neurepidosis hybrida differs from N. minuta Spungis, 1987, a largely similar species, in the following characters (see Fig. 20 versus figs 69A–B in Jaschhof & Jaschhof (2013)): the gonostylus is less strongly bent; the gonostylar apex has large, dense microtrichia (↓ 1, microtrichia inconspicuous in N. minuta); the gonocoxal emargination is evenly rounded (↓ 2, slightly V-shaped in N. minuta); the anterior processes of the gonocoxal apodemes are markedly shorter; and the posterior edge of the ninth tergite has a somewhat protruding, T-shaped sclerotization medially (↓ 3, posterior edge sinuous medially in N. minuta). Females and larvae of N. hybrida remain unknown. Other male characters. Body size 1.6–1.7 mm. Head. Eye bridge 1–2 ommatidia long dorsally. Neck of fourth flagellomere 1.4 times the length of node; circumfila with 2 long posterior extensions (Fig. 21). Wing 3.2– 3.3(–3.9) times longer than wide. Genitalia (Fig. 20). Gonocoxae sparsely setose ventrally, markedly narrowed ventrobasally, an extensively pigmented area below the emargination. Gonostylus convex; apex bent, pointed. Tegmen slender, slightly tapered towards apex, lateral edges slightly reinforced; apex nearly tubular. Base of ejaculatory apodeme strongly enlarged, rounded, weakly sclerotized; apex membranous. Remark on variation. One of the paratypes has exceptionally narrow wings, thereby causing the enormous variation in wing shape described above. Etymology. The species name, a Latin adjective meaning hybrid or intermediate, refers to the fact that the genitalic morphology of N. hybrida equals a composite of structures found in various other Neurepidosis. Type material. Holotype. Male, Sweden, Småland, Nybro, Bäckebo, Grytsjön Nature Reserve, hay meadow at edge of mixed taiga forest, 12–18 July 2005, Malaise trap, Swedish Malaise Trap Project (trap 1001, collecting event 1333) (spm. no.
