( Fig. 44 ; Pl. 5A; Pl. 7K) FIGURE 44. Impatiophila menghaiensis Fu & Gao , sp. nov. Adult male (paratype, #00397) and female (paratype, #01440): A, periphallic organs (caudolateral view); B, caudoventral part of epandrium; C, surstylus (caudal view); D, tenth sternite; E, phallic organs (dorsal view); F, phallic organs (lateral view); G, oviscapt (lateral view); H, oviscapt (ventral view). Diagnosis. Abdominal tergites unicolorously glossy black (Pl. 5A). Labellum with 7 pseudotracheae per side. Tenth sternite with very shallow, W-shaped notch on dorsal margin ( Fig. 44 D). Paramere distally narrowing, apically somewhat obliquely truncate ( Fig. 44 F). Gonopod very broad and apically protruded ventrad in lateral view ( Fig. 44 F). Oviscapt valve relatively long, 1/5 as wide as long in ventral view ( Fig. 44 G). Description (♂, ♀). Head: Cibarium with 3 medial and 4 posterior sensilla per side. Thorax (Pl. 5A): Postpronotum blackish brown; scutum and scutellum glossy black; pleura blackish brown to black. Wing (Pl. 5A) pale brown. C1 setae 2, subequal. Haltere pale yellow. Legs (Pl. 5A) yellowish brown. Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside. Abdomen: Sternites grayish yellow. Male terminalia ( Fig. 44 A −F): Epandrium densely pubescent on posterior portion of dorsal 2/3, with ca 15 long setae on ventral half and ca. 15 shorter setae on caudoventral portion. Surstylus with 1 seta in addition to 2 thick, relatively long, upturned prensisetae above caudodorsal corner, 7 prensisetae along distal margin and 1 seta at ventral apex. Tenth sternite slightly wider than long, dorsally slightly dilated. Cercus pubescent on anterior portion, with ca. 26 long setae. Hypandrium somewhat trapeziform, posteriorly broader. Paramere smooth on dorsal and ventral margins, with 7 sensilla. Aedeagal basal process slightly shorter than 1/2 length of paramere. Female terminalia ( Fig. 44 G, H; Pl. 7K): Oviscapt valve brown, obliquely truncate on dorsosubapical margin in lateral view, with 4−5 dorsal ovisensilla and 19−23 ventral ones arranged entirely at nearly equal intervals. Spermathecal capsule brown; introvert depth of duct about 4/5 of capsule height.
