( Figs 22–27 ) Diagnosis . Scutum with brownish median longitudinal stripe; fore femur with 1 basiventral denticle; epandrium fused to hypandrium ( Fig. 26 ); surstylus rounded with spine-like setae on inner face ( Figs 24, 27 ). Description . Male ( Fig. 22 ). 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 1.5X as long as wide, stylus ~ 0.9X as long as postpedicel. Thorax ( Fig. 22 ). 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 C1, on scutellum and mediotergite; antepronotum with anterior margin almost straight and scutum with yellow setae, very small and fine except 1 notopleural. Legs ( Fig. 22 ). Whitish yellow. C1 ~ 1.2X longer than distance between C1 and C2, 5X as long as wide with some pale dorsoapical setae. F1 about 1.1X as long as C1, 4.0–4.5X 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. T1 ~ 0.7X as long as F1, 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 T1 but with strong apical spine. Mid- and hind legs slender with fine setae; T3 with ‘comb’ of short setae posteroapically. Wing ( Fig. 23 ). Membrane faintly yellow, veins yellowish; R2+3 long and straight, not strongly curved towards C apically, joining C ~ 0.7 distance between end of R1 and R4; R4+5 fork angle acute (~ 70°), distal to position of M1+2 fork by about 2X length of 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. 22 ). Tergites 1–6 and 8 brownish; tergite 7 and sternites yellowish; tergite 8 shorter than sternite 8. Terminalia . Brown. Cercus narrow, widened basally ( Fig. 24 ), left and right cerci closely approximated anterodorsally ( Fig. 25 ), distinctly setose on outer face. Epandrium widened basally, pointed at apex ( Fig. 24 ), scattered setae on outer face; fused with hypandrium ( Fig. 26 ). Surstylus subrounded, with spine-like setae on inner face ( Figs 24, 26, 27 ). Hypandrium subtriangular, with distinct setae ( Fig. 26 ); gonocoxal apodeme projecting as narrow process just beyond anterior margin of hypandrium ( Fig. 24 ). Subepandrial sclerite concave on anterior margin, without posterior processes. Phallus sclerotized ( Fig. 27 ), extending well beyond hypandrium apex, with pointed dorsal projection, membranous area apically with scattered spicules ( Fig. 27 ). Ejaculatory apodeme unilamellar, flattened anteroposteriorly ( Fig. 26 ). 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. 25º09'21,5''S – 53º49'44''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 26 , 55 ), subepandrial sclerite without posterior process and ejaculatory apodeme unilamellar, flattened anteroposteriorly ( Figs 26 , 53 ). Hemerodromia cummingi sp. nov. has F1 with basiventral denticle; tergite 7 and sternites yellow; and phallus without apical sclerotized hook-like process ( Fig. 27 ). In H. ubajaraensis sp. nov. F1 lacks a basiventral denticle; tergite 7 and sternites brownish; and phallus with apical sclerotized hook-like process ( Fig. 54 ).
