Paramere longer than twice of width, smooth on dorsal and ventral margins, with 5 sensilla much more widely spaced distally ( Fig. 42 F). Tenth sternite as long as wide, nearly parallel-sided ( Fig. 42 D). Oviscapt valve with 5 dorsal ovisensilla ( Fig. 42 G). Description (♂, ♀).

Adult male (holotype, #00202) and female (paratype, #01407): 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). Thorax (Pl. 4G): Postpronotum blackish brown; scutum and scutellum glossy black; pleura blackish brown to black. Wing (Pl. 4G) hyaline, slightly infuscate. C1 setae 2, subequal. Haltere yellow. Legs (Pl. 4G) yellowish brown. Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside. Abdomen: Sternites grayish brown. Male terminalia ( Fig. 42 A −F): Epandrium densely pubescent except for anterior margin and ventral 1/3, with ca 15 long setae on ventral half and ca. 20 shorter setae on caudoventral portion. Surstylus with 1 thick seta in addition to 1 stout, upturned prensiseta above caudodorsal corner, 8 prensisetae along distal margin and 1 seta at ventral apex. Tenth sternite with W-shaped notch medially on dorsal margin. Cercus pubescent on anterior portion, with ca. 25 long setae. Hypandrium slightly narrowing anteriorly, roundish on anterior margin. Gonopod somewhat fan-shaped and apically more or less acute in lateral view. Aedeagal basal process about 1/2 length of paramere. Female terminalia ( Fig. 42 G, H; Pl. 7I ): Oviscapt valve yellowish brown, obliquely truncate on dorsosubapical margin in lateral view, with 13–14 ventral ovisensilla arranged entirely at nearly equal intervals. Spermathecal capsule brown; introvert depth of duct about 4/5 of capsule height.
