21) Impatiophila latipennata Fu & Gao View in CoL , sp. nov.

( Fig. 31 View FIGURE 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 View FIGURE 31 A). Tenth sternite somewhat cordiform, with deep, narrow, V-shaped, median notch on dorsal margin ( Fig. 31 View FIGURE 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 View FIGURE 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 View FIGURE 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.
