description
Figs 20 – 21
diagnosis
Diagnosis. Neurepidosis hybrida differs from N. minuta Spungis, 1987, a largely similar species, in the following characters (see Fig. 20 versus figs 69 A – 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.
discussion
Remark on variation. One of the paratypes has exceptionally narrow wings, thereby causing the enormous variation in wing shape described above.
etymology
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.
