Hemerodromia breviradia  sp. nov.

( Figs 9–15View FIGURES 9 – 15)

Diagnosis. Vei n R 2 + 3 short and straight, joining C ~ 0.2 distance between end of R 1 and R 4 ( Fig. 10View FIGURES 9 – 15); cell bm+dm long, ending after at level of R 1, ~ 2.5 X as long as cell br ( Fig. 10View FIGURES 9 – 15); cercus narrow with pointed apex ( Figs 11, 12View FIGURES 9 – 15); phallus sclerotized, extending just beyond the hypandrium apex ( Fig. 14View FIGURES 9 – 15).

Description. Male ( Fig. 9View FIGURES 9 – 15). Head. Dark brown to black, antenna and mouthparts yellow with all setae whitish; ocellar triangle with 1 pair of proclinate ocellar setae; anterior ocellus larger. Eyes iridescent black, very narrowly separated on face which bears fine reclinate setulae. Frons with 1–2 setulae; 3–4 pairs of vertical setae contiguous with uniseriate 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 1.3 X as long as wide, stylus ~ 0.8 X as long as postpedicel. Thorax ( Fig. 9View FIGURES 9 – 15). Elongate, slightly arched ventrally; dorsum yellow; antepronotum with anterior margin almost straight; scutum with yellow setae, very small and fine except 1 notopleural and 1 pair of scutellars. Leg ( Fig. 9View FIGURES 9 – 15). Whitish yellow. C 1 ~ 1.3 X longer than distance between C 1 and C2, 5X as long as wide with some pale dorsoapical setae. F 1 ~ 1.1 X as long as C 1, 3.5 –4.0X as long as wide. Femoral formula 7 / 15–16 / 13 –14/ 6–7, basal spines stronger; denticles confined to distal 0.7, becoming closer together distally, black, 2 rows linear, without distal discontinuity. T 1 ~ 0.7 X as long as F 1, evenly curved, ventral face shallowly concave; with 2 rows of 12–15 sharply pointed spinose setae ventrally; dorsal ciliation of decumbent short pale setulae, denser distally; without apicoventral extension on T 1 but with strong apical spine. Mid and hind legs slender with fine setae but T 3 with ‘comb’ of short setae posteroapically. Wing ( Fig. 10View FIGURES 9 – 15). Membrane faintly yellow, veins brownish; R 2 + 3 short and straight, not strongly curved towards C apically, joining C ~ 0.2 distance between end of R 1 and R 4; R 4 + 5 fork angle acute (~ 60 °), distal to position of M 1 + 2 fork by about same length as R 4; R 5 and M 1 convergent distally; vein R 5 ~ 2.0X as long as R 4; cell bm+dm long, ending after at level of R 1, ~ 2.5 X as long as cell br. Halter whitish yellow. Abdomen. Tergites 1–6 and 8 brownish; tergite 7 and sternites yellowish. Tergites 7–8 with pale strong setae laterally on posterior margin; tergite 8 slightly shorter than sternite 8. Terminalia. Brown. Cercus narrow with pointed apex, distinctly setose on outer face ( Fig. 11View FIGURES 9 – 15); right and left cerci close together dorsally ( Fig. 12View FIGURES 9 – 15). Epandrium wide basally and gradually tapered towards apex ( Fig. 11View FIGURES 9 – 15), scattered setae on outer face and spine-like setae apically on inner face ( Figs 11, 13View FIGURES 9 – 15). Surstylus absent. Hypandrium rather subtriangular ( Fig. 15View FIGURES 9 – 15), without distinct setae; gonocoxal apodemes projecting as narrow process just beyond anterior margin of hypandrium ( Figs 11, 14View FIGURES 9 – 15). Subepandrial sclerite with median triangular anterior projection and median rounded posterior projection ( Fig. 13View FIGURES 9 – 15). Phallus extending just beyond apex of hypandrium, with pointed dorsal projection and median membranous area apically ( Fig. 14View FIGURES 9 – 15). Ejaculatory apodeme lamella flattened in vertical plane, short ( Figs 11, 14View FIGURES 9 – 15). Body length: 2.0 mm; wing length: 1.4 mm. Female: Unknown.

Type material. HOLOTYPE ♂ “BR[asil], AM[azonas], Manaus. R.[eserva] Ducke. Ig.[arapé] Bolivia. Malaise. 18–22.ii. 2003. J.M.F.Ribeiro” ( INPA). PARATYPES: same data as holotype (1 ♂, INPA); Idem, Ig. Ipiranga, Arm, Malaise, v. 2003, J.M.F. Ribeiro, J. Vidal & J. Vidal (1 ♂, INPA); Idem, PDBFF /WWF, Proj: Bert Klein. xi. 1985, Malaise, Reserva 1301 (1 ♂, INPA).

Holotype condition. Wing mounted on microslide. Abdomen in microtube with glycerin.

Etymology. From the Latin brevius (abbreviate) which refers to the abbreviated R 2 + 3.

Variations. Paratypes with body length varying from 1.8 mm to 2.5 mm and wing length varying from 1.2 mm to 1.8 mm.

Remarks. Hemerodromia breviradia  sp. nov. differs from other species of Hemerodromia  by abbreviated R 2 + 3 and ejaculatory apodeme with short lamella ( Figs 11, 14View FIGURES 9 – 15).
