description: 21) Impatiophila latipennata Fu & Gao, sp. nov.
(Fig. 31; Pl. 3D; Pl. 6S)
Diagnosis. Heavy, peg-like setae of middle row on 2nd costal section interspersed with weak, trichoid ones. Hindleg tibia with 1 black, apically blunt, stout spine at outer apex on underside. Epandrium deeply concaved on lower caudal margin, resulting in prominent caudoventral lobe (Fig. 31 A). Tenth sternite somewhat cordiform, with deep, narrow, V-shaped, median notch on dorsal margin (Fig. 31 D).
Description (♂, ♀). Head: Cibarium with 2 medial and 6 posterior sensilla per side.
Thorax (Pl. 3D): Postpronotum, scutum and scutellum glossy black; pleura blackish brown to black.
Wing (Pl. 3D) pale brown; veins dark brown. C1 setae 2, ventral one shorter and thinner. Haltere grayish yellow.
Legs (Pl. 3D) yellowish brown.
Abdomen (Pl. 3D): Tergites glossy black. Sternites grayish brown; male VI posteriorly wider, concave on posterior margin.
Male terminalia (Fig. 31 A −F): Epandrium pubescent posteriorly on dorsal 1/2, ventrally with ca. 10 setae; caudoventral lobe with ca. 13 setae. Surstylus with 2 setae in addition to 1 stout, upturned prensiseta around caudodorsal corner, 7 apically converging prensisetae along distal margin and 3 short setae near ventral apex. Cercus sparsely pubescent on anteromedial portion, with ca. 20 long setae. Hypandrium nearly parallel-sided, roundish on anterior margin. Gonopod apically somewhat acutely projected. Paramere not longer than twice of width, with 7sensilla. Aedeagal basal process about 2/3 length of paramere.
Female terminalia (Fig. 31 G, H; Pl. 6S): Oviscapt valve brown, gently curved on dorsosubapical margin and strongly expanded dorsomedially in lateral view, with 3−4 dorsal ovisensilla, 11−12 lateral ones on slightly convex (in ventral view) margin of apicolateral flap and 9−11 distally slightly increasing in size on convex, ventral margin; apicolateral flap well developed, turnup in lateral view. Spermathecal capsule brown; introvert depth of duct about 1/2 of capsule height.
