description: Hemerodromia collini sp. nov.
(Figs 25–31)
Diagnosis. Best distinguished by the R4+5 fork distal to the position of the M1+2 fork, shorter than the length of R4 (Fig. 26); shape of the male cercus being incurved apically, longer than epandrium in lateral view (Fig. 28) and phallus with two posterolateral pointed projections (Fig. 30).
Description. Male (Fig. 25). Head. Dark brown to black, antenna and mouthparts yellow with all setae whitish; ocellar triangle with 1 pair of proclinate setae; anterior ocellus larger. Eyes iridescent black, very narrowly separated on face which bears fine reclinate setulae. Frons with 1–2 setulae; one pair of distinct vertical setae contiguous with uniseriate smaller postocular setae; occiput bearing scattered fine hairs. Clypeus with rather dense short downwardly directed pile. Proboscis slightly curved with setae yellow. Antenna with scape and pedicel bearing distinct short dorsal setulae; postpedicel about 1.5X as long as wide, stylus ~ 0.8X as long as postpedicel. Thorax (Fig. 25). Elongate, slightly arched ventrally; dorsum yellow, except brownish on mediotergite and median stripe on prothoracic collar; antepronotum with anterior margin almost straight; scutum with yellow setae, very small and fine except 1 notopleural. Legs (Fig. 25). Whitish yellow. C1 ~ 1.4X longer than distance between C1 and C2, 6X as long as wide. F1 ~ 1.1X as long as C1, 4X as long as wide. Femoral formula 7/16–17/1+14–15/5; denticles confined to distal 0.7, 2 rows linear, black, without distal discontinuity, converging distally but divergent at tip. T1 ~ 0.6X as long as F1, evenly curved, ventral face shallowly concave; with 2 rows of 15–18 sharply pointed spinose setae ventrally; dorsal ciliation of decumbent short pale setulae, denser distally; slight apicoventral extension on T1 bearing strong apical spine. Mid and hind legs slender with fine setae but T3 with ‘comb’ of short setae posteroapically. Wing (Fig. 26). Membrane faintly yellow, veins yellowish; R2+3 long and straight, not strongly curved towards C apically, joining C ~ 0.7–0.8 distance between end of R1 and R4; R4+5 fork acute (~ 60°), distal to position of M1+2 fork by shorter than R4; R5 and M1 diverging distally; vein R5 ~ 3X as long as R4; cell bm+dm short, ending at level of R1, ~ 2X as long as cell br. Halter whitish yellow. Abdomen (Figs 25, 27). Tergites 1 and 7 and sternites yellowish, tergites 2–6 and 8 brownish with distinct setae on posterior margin; tergite 8 shorter than sternite 8. Terminalia. Brownish. Cercus narrow, curved up distally with rounded apex (Figs 27, 28); left and right cerci closely approximated anterodorsally (Fig. 29). Epandrium wide, subrectangular in lateral view, with strong setae on outer face at apex (Fig. 28). Surstylus (Fig. 29) bilobed, with spine-like setae on inner face of outer lobe. Hypandrium rather rounded in ventral view (Fig. 31), not markedly inflated, with distinct setae; gonocoxal apodeme confined to anterior margin of hypandrium, lacking narrow process. Subepandrial sclerite concave on anterior margin, two short finger-like posterior processes with long setae at apex (Fig. 29). Phallus sclerotized with two posterolateral pointed projections, extending well beyond hypandrium apex, apical membranous area covered with minute dark spicules (Fig. 30). Ejaculatory apodeme absent. Body length: 3.1 mm; wing length: 2.4 mm. Female: Unknown.
Type material: HOLOTYPE ♂ “ BRASIL, Amazonas, Manaus, R.[eserva] Ducke, 5.viii.1993. Ig.[arapé] Acará. Malaise J. Vidal” (INPA). PARATYPES. Same data as holotype (4 ♂, MZUSP); Idem, 2.ix.1993 (3 ♂, NMWC); Idem, x.2001, Arm. Malaise, J.F. Vidal (7 ♂, INPA, 4 ♂, MNRJ, 3 ♂, CNC); Idem, Ig. Tinga. Arm. Malaise, iii.2003, J.M.E.Ribeiro, J. Vidal & J. Vidal (1 ♂, MPEG).
Holotype condition. Good condition. Not dissected.
Etymology. The specific epithet is in tribute to J.E. Collin in recognition of his contribution to the knowledge of the Neotropical fauna of Empididae.
Variations. Body varying from 2.8 mm to 3.6 mm. Wing length varying from 2 mm to 2.5 mm.
Remarks. Hemerodromia collini sp. nov. is similar to H. maturaca sp. nov. by the R4+5 fork distal to the position of the M1+2 fork, shorter than the length of R4; subepandrial sclerite with 2 finger-like posterior processes; and epandrium subrectangular. Hemerodromia collini sp. nov. differs from the latter by the shape of the male cercus being incurved apically, and phallus with 2 posterolateral pointed projections. In H. maturaca sp. nov. the cercus is almost straight apically and phallus have no posterolateral pointed projections.
