8) Impatiophila longifolia Fu & Gao View in CoL , sp. nov.

( Fig. 18 View FIGURE 18 ; Pl. 1G; Pl. 6G)

Diagnosis. Heavy, peg-like setae of middle row on 2nd costal section interspersed with weak, trichoid ones ( Fig. 3 View FIGURE 3 G). Abdominal tergites entirely black (Pl. 1G). Hindleg tibia with 2 black, apically blunt, stout spines at outer apex on underside ( Fig. 3 View FIGURE 3 K). Paramere like tip of golf shaft in lateral view ( Fig. 18 View FIGURE 18 F).

Description (♂, ♀). Head: Cibarium with 2−3 medial and 4–6 posterior sensilla per side.

Thorax (Pl. 1G): Postpronotum blackish brown to black; scutum and scutellum black; pleura brown to blackish brown.

Wing (Pl. 1G) pale brown; veins brown. C1 setae 2, subequal. Haltere pale yellow.

Abdomen: Sternites grayish brown; male VI posteriorly wider, nearly straight or slightly concave on posterior margin.

Male terminalia ( Fig. 18 View FIGURE 18 A–F): Epandrium pubescent medially to posteriorly on dorsal 1/2, ventrally with ca. 14 long setae; caudoventral portion broad, apically somewhat truncate, with ca. 15 short, stout setulae. Surstylus with 1 seta in addition to 1 stout, upturned prensiseta at caudodorsal corner, 6 apically converging prensisetae along distal margin and 1 short seta near ventral apex. Tenth sternite warhead-shaped, slightly constrict basolaterally. Cercus pubescent near anterior margin, with ca. 25 long setae. Hypandrium long, largely parallel-sided, anteriorly with distinct apodeme. Gonopod short, apically blunt in lateral view. Paramere 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. 18 View FIGURE 18 G, H; Pl. 6G): Oviscapt valve gently curved on dorsosubapical margin and less expanded dorsomedially in lateral view, with 5 dorsal ovisensilla, 9−10 ones on margin of narrow, apicolateral flap and 7−8 ones distally increasing in size on slightly convex, ventral margin. Spermathecal capsule brown; introvert depth of duct about 1/2 of capsule height.
