Hemerodromia ubajaraensis View in CoL sp. nov.

( Figs 51–55 View FIGURES 51 – 55 )

Diagnosis. Scutum with median longitudinal band; tergites and sternites brownish ( Fig. 51 View 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. 54 View FIGURES 51 – 55 ).

Description. Male ( Fig. 51 View 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 1.3X as long as wide, stylus ~ 0.9X as long as postpedicel. Thorax ( Fig. 51 View 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 C1, scutellum and mediotergite; antepronotum with anterior margin almost straight and scutum with yellow setae, very small and fine except 1 notopleural. Legs ( Fig. 51 View FIGURES 51 – 55 ). Whitish yellow. C1 ~ 1.2X longer than distance between C1 and C2, 5X as long as wide with some pale dorsoapical setae. F1 about 1.2X as long as C1, 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. T1 ~ 0.7X as long as F1, 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 T1, with strong apical spine. Mid- and hind legs slender with fine setae; T3 with ‘comb’ of short setae posteroapically. Wing. Membrane slightly yellow, veins brownish; R2+3 long and straight, not strongly curved towards C apically, joining C ~ 0.7 distance between end of R1 and R4+5; R4+5 fork angle acute (~ 60°), distal to position of M1+2 fork by about same length as R4; R5 and M1 convergent distally; R5 ~ 2.0X as long as R4; cell bm+dm short, ending just before R1, ~2.0X as long as cell br. Halter whitish yellow. Abdomen ( Fig. 51 View FIGURES 51 – 55 ). Tergites and sternites brownish; tergite 8 shorter than sternite 8. Terminalia. Brown. Cercus narrow, pointed apically ( Fig. 52 View FIGURES 51 – 55 ), left and right cerci closely approximated anterodorsally, distinctly setose on outer face. Epandrium widened basally, slightly pointed apically ( Fig. 52 View FIGURES 51 – 55 ), scattered setae on outer; fused with hypandrium ( Fig. 55 View FIGURES 51 – 55 ). Surstylus subrounded, with setae at apex ( Figs 52, 54 View FIGURES 51 – 55 ). Hypandrium subrectangular ( Fig. 55 View FIGURES 51 – 55 ), not inflated, with distinct setae; gonocoxal apodeme projecting as narrow process just beyond anterior margin of hypandrium ( Figs 52, 54 View FIGURES 51 – 55 ). Subepandrial sclerite narrow, without posterior process ( Fig. 53 View 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. 54 View FIGURES 51 – 55 ). Ejaculatory apodeme unilamellar flattened anteroposteriorly ( Fig. 53 View 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. 03º50'13''S- 40º54'35''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 26 View FIGURES 22 – 27 , 55 View FIGURES 51 – 55 ), subepandrial sclerite without posterior process and ejaculatory apodeme unilamellar flattened anteroposteriorly ( Figs 26 View FIGURES 22 – 27 , 53 View FIGURES 51 – 55 ). Hemerodromia ubajaraensis sp. nov. has F1 without basiventral denticle; tergite 7 and sternites brownish; and phallus with apical sclerotized hook-like process ( Fig. 54 View FIGURES 51 – 55 ). In H. cummingi sp. nov. F1 has basiventral denticle; tergite 7 and sternites yellow; and phallus without apical sclerotized hook-like process ( Fig. 27 View FIGURES 22 – 27 ).
