description: 6) Impatiophila tongmaiensis Fu & Gao, sp. nov.
(Fig. 16; Pl. 1E; Pl. 6E)
Diagnosis. Setae of middle row on 2nd costal section all heavy, peg-like, present beyond tip of R2+3. Abdominal tergite V with caudal, black band medially neither interrupted/constricted nor protruded (Pl. 1E). Hindleg tibia with 1 black, apically blunt, stout spine at outer apex on underside.
Description (♂, ♀). Head (Pl. 1E): Eyes brownish. Cibarium with 2or 3 medial and 4–6 posterior sensilla per side.
Thorax (Pl. 1E): Postpronotum yellowish brown to brown; scutum black, pale along transverse suture, notopleural line and lines running through ipsilateral, dorsocentral setae and extending to notum; scutellum black, pale laterally; pleura brown to blackish brown.
Wing (Pl. 1E) hyaline; veins yellowish brown. C1 setae 2; ventral one thinner and shorter. Haltere pale yellow. Abdomen (Pl. 1E): Tergites each with broad, blackish brown to black, caudal band; bands on II −IV medially with narrow, deep notches. Sternites grayish brown; male VI posteriorly wider, concave on posterior margin.
Male terminalia (Fig. 16 A −F): Epandrium sparsely and patchily pubescent except for anterior and ventral portions, ventrally with ca. 12 long setae; caudoventral portion narrow, somewhat pointed apically, with a patch of ca. 18 setulae. Surstylus with 1 seta in addition to 1 stout, upturned prensiseta at caudodorsal corner, 6 apically converging prensisetae along distal margin and 1 seta near ventral apex. Tenth sternite dorsally broader, slightly pointed at apex of convex, dorsal margin. Cercus anteromedially pubescent in patch, with ca. 28 long setae. Hypandrium somewhat quadrate, 3/4 as wide as long. Gonopod apically very sharp, curved ventrad. Paramere nearly straight in lateral view, longer than twice of width in lateral view, with 6 sensilla. Aedeagal basal process slightly longer than 1/2 length of paramere.
Female terminalia (Fig. 16 G, H; Pl. 6E): Oviscapt valve gently curved on dorsosubapical margin and less expanded dorsomedially in lateral view, with 5 dorsal and 18−19 lateral ovisensilla and 13 distally increasing in size on nearly straight, ventral margin. Spermathecal capsule brown; introvert depth of duct about 1/2 of capsule height.
