description: 29) Impatiophila motuoensis Fu & Gao, sp. nov.
(Fig. 35; Pl. 3H; Pl. 7B)
Diagnosis. Abdominal tergite I grayish yellow; II and III each with black, medially widely interrupted, caudal band; IV with caudal band medially widely constricted; V and VI nearly entirely black (Pl. 3H). Tenth sternite flexuous on lateral margins, with W-shaped notch medially on dorsal margin (Fig. 35 D).
Description (♂, ♀). Head: Cibarium with 2−3 medial and 4 posterior sensilla per side. Labellum with 5 pseudotracheae per side.
Thorax (Pl. 3H): Postpronotum dark brown; scutum and scutellum black; pleura brown to blackish brown. Wing (Pl. 3H) pale brown; veins brown. C1 setae 2, subequal. Haltere pale yellow.
Legs (Pl. 3H) yellowish brown. Hindleg tarsomere I with 1 black, apically blunt, stout spine at outer apex on underside.
Abdomen: Sternites grayish yellow.
Male terminalia (Fig. 35 A −F): Epandrium pubescent in small patch on caudomedial portion, truncate on ventral margin, with ca. 31 long setae on medial to ventral portion: caudoventral ones more densely distributed. Surstylus with 3 setae in addition to 2 stout, upturned prensisetae around and above caudodorsal corner, 6 prensisetae along distal margin and 2 setae at ventral apex. Cercus unpubescent, with ca. 24 long setae. Hypandrium slightly narrowing anteriorly, slightly (in ventral view) and strongly (in lateral view) constricted around anterior 1/3. Gonopod well developed, more or less straight on dorsal margin in lateral view. Paramere apically obliquely truncate, with 7 sensilla. Aedeagal basal process about 1/2 length of paramere.
Female terminalia (Fig. 35 G, H; Pl. 7B): Oviscapt valve yellowish brown, obliquely truncate on dorsosubapical margin in lateral view, with 4−5 dorsal ovisensilla and 17−18 ventral ones more widely spaced in subdistal portion. Spermathecal capsule dark brown; introvert depth of duct about 4/5 of capsule height.
