Hemerodromia ubajaraensis  sp. nov.

( Figs 51–55View FIGURES 51 – 55)

Diagnosis. Scutum with median longitudinal band; tergites and sternites brownish ( Fig. 51View FIGURES 51 – 55); epandrium fused to hypandrium; phallus with pointed dorsal projection apically and membranous area covered with spicules and hooklike bifid apical process ( Fig. 54View FIGURES 51 – 55).

Description. Male ( Fig. 51View FIGURES 51 – 55). 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 bearing fine reclinate setulae. Frons with 1–2 frontal setulae; 2–3 pairs of vertical setae contiguous with uniseriate row of postocular setae. Occiput bearing scattered fine hairs. Clypeus with rather dense, short downwardly directed pile. Proboscis slightly curved with yellow setae. Antenna with scape and pedicel bearing distinct, short dorsal setulae; postpedicel about 1.3 X as long as wide, stylus ~ 0.9 X as long as postpedicel. Thorax ( Fig. 51View FIGURES 51 – 55). Elongate, slightly arched ventrally; thoracic dorsum yellowish, except brownish on prothoracic collar, narrowly behind postpronotal lobe, above wing base, median longitudinal band on scutum, suture between katepisternum and meron, katepisternum ventrally behind C 1, scutellum and mediotergite; antepronotum with anterior margin almost straight and scutum with yellow setae, very small and fine except 1 notopleural. Legs ( Fig. 51View FIGURES 51 – 55). Whitish yellow. C 1 ~ 1.2 X longer than distance between C 1 and C2, 5X as long as wide with some pale dorsoapical setae. F 1 about 1.2 X as long as C 1, 3.5 –4.0X as long as wide. Femoral formula 6– 9 / 20–21 / 22–23 / 6; denticles confined to distal 0.7, becoming closer together distally, black, 2 rows linear, without distal discontinuity, diverging abruptly at extreme apex. T 1 ~ 0.7 X as long as F 1, evenly curved, ventral face shallowly concave; about 17–19 sharply pointed spinose setae ventrally; dorsal ciliation of decumbent short, pale setulae, denser distally; without apicoventral extension on T 1, with strong apical spine. Mid- and hind legs slender with fine setae; T 3 with ‘comb’ of short setae posteroapically. Wing. Membrane slightly yellow, veins brownish; R 2 + 3 long and straight, not strongly curved towards C apically, joining C ~ 0.7 distance between end of R 1 and R 4 + 5; 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; R 5 ~ 2.0X as long as R 4; cell bm+dm short, ending just before R 1, ~2.0X as long as cell br. Halter whitish yellow. Abdomen ( Fig. 51View FIGURES 51 – 55). Tergites and sternites brownish; tergite 8 shorter than sternite 8. Terminalia. Brown. Cercus narrow, pointed apically ( Fig. 52View FIGURES 51 – 55), left and right cerci closely approximated anterodorsally, distinctly setose on outer face. Epandrium widened basally, slightly pointed apically ( Fig. 52View FIGURES 51 – 55), scattered setae on outer; fused with hypandrium ( Fig. 55View FIGURES 51 – 55). Surstylus subrounded, with setae at apex ( Figs 52, 54View FIGURES 51 – 55). Hypandrium subrectangular ( Fig. 55View FIGURES 51 – 55), not inflated, with distinct setae; gonocoxal apodeme projecting as narrow process just beyond anterior margin of hypandrium ( Figs 52, 54View FIGURES 51 – 55). Subepandrial sclerite narrow, without posterior process ( Fig. 53View FIGURES 51 – 55). Phallus sclerotized basally, extending just beyond hypandrium apex, with pointed dorsal projection apically; membranous area covered with spicules and hook-like bifid apical process ( Fig. 54View FIGURES 51 – 55). Ejaculatory apodeme unilamellar flattened anteroposteriorly ( Fig. 53View FIGURES 51 – 55). Specimen length: 2.7 mm; wing length: 2.1 mm. Female. Unknown.

Geographic distribution. Brazil (Ceará State).

Type material. HOLOTYPE #m, “BR[azil], CE[Ceará], Ubajara, Parque Nac.[onal] de Ubajara, Cachoeira do Cafundó. 03º 50 ' 13 ''S- 40 º 54 ' 35 ''W, Armadilha Malaise, 15–20.ii. 2013. J.A. Rafael, F. Limeira-de-Oliveira cols.” ( CZMA). Paratypes. Same data as holotype (2 ♂, CZMA, 2 ♂, INPA).

Holotype condition. Good. Not dissected.

Etymology. The specific epithet refers to the name of the place where the specimens were collected.

Variations. Body length varying from 2.0– 3.1 mm and wing length varying from 1.3–2.2 mm.

Remarks. Hemerodromia ubajaraensis  sp. nov. is similar to H. cummingi  sp. nov in having the epandrium fused to hypandrium ( Figs 26View FIGURES 22 – 27, 55View FIGURES 51 – 55), subepandrial sclerite without posterior process and ejaculatory apodeme unilamellar flattened anteroposteriorly ( Figs 26View FIGURES 22 – 27, 53View FIGURES 51 – 55). Hemerodromia ubajaraensis  sp. nov. has F 1 without basiventral denticle; tergite 7 and sternites brownish; and phallus with apical sclerotized hook-like process ( Fig. 54View FIGURES 51 – 55). In H. cummingi  sp. nov. F 1 has basiventral denticle; tergite 7 and sternites yellow; and phallus without apical sclerotized hook-like process ( Fig. 27View FIGURES 22 – 27).
