Hemerodromia cummingi  sp. nov.

( Figs 22–27View FIGURES 22 – 27)

Diagnosis. Scutum with brownish median longitudinal stripe; fore femur with 1 basiventral denticle; epandrium fused to hypandrium ( Fig. 26View FIGURES 22 – 27); surstylus rounded with spine-like setae on inner face ( Figs 24, 27View FIGURES 22 – 27).

Description. Male ( Fig. 22View FIGURES 22 – 27). 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; small 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 setae yellow. Antenna with scape and pedicel bearing distinct, short dorsal setulae; postpedicel about 1.5 X as long as wide, stylus ~ 0.9 X as long as postpedicel. Thorax ( Fig. 22View FIGURES 22 – 27). Elongate, arched ventrally; thoracic dorsum yellow, except brownish on prothoracic collar, narrowly behind postpronotal lobe, median longitudinal stripe, posterolaterally above wing base on scutum, anatergite, suture between katepisternum and meron, katepisternum ventrally behind C 1, on scutellum and mediotergite; antepronotum with anterior margin almost straight and scutum with yellow setae, very small and fine except 1 notopleural. Legs ( Fig. 22View FIGURES 22 – 27). 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 1.1 X as long as C 1, 4.0– 4.5 X as long as wide. Femoral formula 6– 7 / 20–21 / 1 + 14–15 / 7; denticles confined to distal 0.8, 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; about 15–18 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; T 3 with ‘comb’ of short setae posteroapically. Wing ( Fig. 23View FIGURES 22 – 27). Membrane faintly yellow, veins yellowish; 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; R 4 + 5 fork angle acute (~ 70 °), distal to position of M 1 + 2 fork by about 2 X length of 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. 22View FIGURES 22 – 27). Tergites 1–6 and 8 brownish; tergite 7 and sternites yellowish; tergite 8 shorter than sternite 8. Terminalia. Brown. Cercus narrow, widened basally ( Fig. 24View FIGURES 22 – 27), left and right cerci closely approximated anterodorsally ( Fig. 25View FIGURES 22 – 27), distinctly setose on outer face. Epandrium widened basally, pointed at apex ( Fig. 24View FIGURES 22 – 27), scattered setae on outer face; fused with hypandrium ( Fig. 26View FIGURES 22 – 27). Surstylus subrounded, with spine-like setae on inner face ( Figs 24, 26, 27View FIGURES 22 – 27). Hypandrium subtriangular, with distinct setae ( Fig. 26View FIGURES 22 – 27); gonocoxal apodeme projecting as narrow process just beyond anterior margin of hypandrium ( Fig. 24View FIGURES 22 – 27). Subepandrial sclerite concave on anterior margin, without posterior processes. Phallus sclerotized ( Fig. 27View FIGURES 22 – 27), extending well beyond hypandrium apex, with pointed dorsal projection, membranous area apically with scattered spicules ( Fig. 27View FIGURES 22 – 27). Ejaculatory apodeme unilamellar, flattened anteroposteriorly ( Fig. 26View FIGURES 22 – 27). Specimen length: 2.5 mm; wing length: 2.1 mm. Female: Unknown.

Geographic distribution. Brazil (Paraná State).

Type material. HOLOTYPE ♂, “BR[azil], PR[Paraná]. Céu Azul, P.[arque] N.[acional] Iguaçu, Rio Azul. 25 º09'21,5''S – 53 º 49 ' 44 ''W, 510 m, 6–8.ix. 2012, Malaise. D.M.Takyia, A.P.M.Santos, G.Jardim.” ( INPA). Paratypes: Same data as holotype (2 ♂, INPA).

Holotype condition. Abdomen in microtube with glycerin.

Etymology. The specific epithet is in tribute to Jeffrey Cumming in recognition of his contribution to the knowledge of the Empidoidea fauna.

Variations. Paratypes with body length varying from 2.1–2.8 mm and wing length varying from 1.5–2.2 mm.

Remarks. Hemerodromia cummingi  sp. nov. is similar to H. ubajaraensis  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 cummingi  sp. nov. has F 1 with basiventral denticle; tergite 7 and sternites yellow; and phallus without apical sclerotized hook-like process ( Fig. 27View FIGURES 22 – 27). In H. ubajaraensis  sp. nov. F 1 lacks a basiventral denticle; tergite 7 and sternites brownish; and phallus with apical sclerotized hook-like process ( Fig. 54View FIGURES 51 – 55).
