( Figure 3 (a–k)) Diagnosis Elongate bristles on tergum VII with curved apices. Gonocoxite arm with acute apex, apically pilose with row of six small, rod-like setae. Two pairs of parameres, the dorsal cuneiform and the ventral lanciform. Ejaculatory apodeme 5.7 times the length of dorsal parameres. Description Adult male. Head subcircular ( Figure 3 (a)). Antenna incomplete in studied specimens; scape longer than pedicel; scape subcylindrical and pedicel subespherical; basal flagellomeres pyriform and eccentric; ascoid 1.4 times the length of flagellomere ( Figure 3 (h)). Palpus three-segmented; first segment with sensilla in depressed pit on inner side; palpus formula 1.0:0.7:0.9 ( Figure 3 (d)). Wing ( Figure 3 (b)): Sc incomplete; R4 + 5 incomplete at base; r-m and m-cu absent. Elongate bristles of tergum VII with curved apices ( Figure 3 (f)). Male terminalia: Hypandrium fused with gonocoxite. Gonocoxite with posterior arm curved to the midline, apex acute, apically pilose with row of six small, rod-like setae ( Figure 3 (c,j)). Gonostylus digitiform with apex curved upward. Two pairs of parameres present, the dorsal sclerotised and cuneiform and the ventral lanciform ( Figure 3 (e,j,k)). Aedeagus bifid and convergent. Ejaculatory apodeme 5.7 times the length of the dorsal parameres. ( Figure 3 (j,k)). Epandrium pilose, wider than long, trapezoidal ( Figure 3 (i)). Cercus pilose, digitiform in ventral view, with a projection with long bristles in dorsal view ( Figure 3 (g)). Hypoproct with rounded apex and apical micropilosity ( Figure 3 (i)).

Figure 3. (a–k) Trichomyia gabia sp. nov. (a) Head; (b) right wing; (c) arm of gonocoxite, in ventral view; (d) palpus; (e) male terminalia, lateral; (f) tergum VII; (g) cercus, in lateral view; (h) scape, pedicel and basal flagellomeres; (i) cerci, epandrium, hypoproct; (j) male terminalia, dorsal; (k) aedeagus and parameres. Abbreviations: aed = aedeagus, agx = arm of gonocoxite, cer = cercus, ep = epandrium, gst = gonostylus, hyp = hypoproct, pmd = dorsal paramere, pmv = ventral paramere, tgVII = tergum VII. Distribution Brazil ( Espírito Santo ). Etymology The epithet gabia is to honour the daughters of the author Claudiney Biral dos Santos: Gabriela (nickname Gabi ) and Beatriz ( Bia ). Remarks Trichomyia gabia has genitalia with rod-like setae on the arm of gonocoxite as in most species of the subgenus, such as T. amazonensis Araújo & Bravo, 2012 ; T. atlantica Araújo & Bravo, 2012 ; T. gustavoi sp. nov. ; and T. menezei sp. nov. Also, T. gabia has the cercus elongate, digitiform with apical elongated setae, which is unique for the subgenus: in Septemtrichomyia the cercus is usually shorter than the epandrium, cuneiform or triangular, not trapezoid.
