description: 12) Impatiophila viasericaria Fu & Gao, sp. nov.
(Fig. 22; Pl. 2C; Pl. 6K)
Diagnosis. Setae of middle row on 2nd costal section mostly heavy, peg-like setae, but not reaching R2+3. Hindleg tibia with 1 black, apically blunt, stout spine at outer apex on underside. Tenth sternite ventrally narrowing, notched medially on dorsal margin (Fig. 22 D).
Description (♂, ♀). Head: Cibarium with 3 medial and 4−5 posterior sensilla per side.
Thorax (Pl. 2C): Scutum black; scutellum blackish brown to black, paler laterally; pleura yellowish brown except blackish brown mesopleuron.
Wing (Pl. 2C) slightly fuscous, pale brown; veins brown; C1 setea 2, ventral one shorter and thinner. Haltere whitish yellow.
Legs (Pl. 2C) pale yellowish brown.
Abdomen: Tergites variable in pigmentation pattern: nearly entirely black except for blackish brown I in some specimens including the holotype (Fig. 8 D, Pl. 2C), while III −V each with caudal band medially protruded in some others (Fig. 8 A −C). Sternites grayish yellow; male VI longer than wide.
Male terminalia (Fig. 22 A −F): Epandrium pubescent near posterior margin of dorsal 1/2, ventrally with 11 long setae; caudoventral portion rounded apically, with ca. 14 short, stout setulae. Surstylus with 1 seta in addition to 1 stout, upturned prensiseta around caudodorsal corner, 6 apically converging prensisetae along distal margin and 2 short setae near ventral apex. Cercus pubescent near anterior margin, with ca. 21 long setae. Hypandrium slightly narrowing anteriorly. Gonopod short, apically slightly curved ventrad, blunt hook-like in lateral view. Paramere auricular, with somewhat irregularly waved dorsal margin in lateral view, not longer than twice of width, with 6 sensilla. Aedeagal basal process 2/3 as long as paramere.
Female terminalia (Fig. 22 G, H; P1. 6K): Oviscapt valve gently curved on dorsosubapical margin and less expanded dorsomedially in lateral view, with 4 dorsal ovisensilla, 13−14 lateral ones on margin of relatively narrow, apicolateral flap and 9−11 distally increasing in size on distally concave, ventral margin. Spermathecal capsule dark brown; introvert depth of duct about 1/2 of capsule height.
