Diagnosis. Abdominal tergites III −V each with broad, blackish brown to black, caudal band medially narrowly interrupted or notched (Pl. 2H). Setae of middle row on 2nd costal section all heavy, peg-like setae, present beyond tip of R2+3. Tenth sternite medially slightly convex on dorsal margin, dorsally dilated (Fig. 27 D). Oviscapt valve with 13 lateral ovisensilla on slightly convex (in ventral view) margin of apicolateral flap (Fig. 27 H).

Description (♂, ♀). Head: Cibarium with 3 medial and 5 posterior sensilla per side.

Thorax (Pl. 2H): Postpronotum yellowish brown; scutum black; scutellum black, laterally brown; pleura dark brown to blackish brown.

Wing (Pl. 2H) pale brown; veins yellowish brown. C1 setae 2, ventral one shorter and thinner. Haltere whitish yellow.

Legs: (PL. 2H): Hindleg tibia without black, apically blunt, stout spine at outer apex on underside.

Male terminalia (Fig. 27 A −F): Epandrium posteriorly pubescent on dorsal 1/2, ventrally with ca. 8 long setae; caudoventral portion broad, somewhat angular dorso-apically, with ca. 20 short spines. Surstylus with 2 thick setae in addition to 1 stout, upturned prensiseta around caudodorsal corner, 4 apically converging prensisetae along distal margin and 3 short setae near ventral apex. Cercus pubescent in patches nearly overall, with ca. 31 long setae. Hypandrium 2/3 as wide as long, nearly parallel-sided. Gonopod somewhat triangular, pointed apically in lateral view. Paramere much longer than twice of width, gently curved dorsad, with 6 sensilla. Aedeagal basal process nearly 1/2 length of paramere.

Female terminalia (Fig. 27 G, H; Pl. 6O): Oviscapt valve brown, gently curved on dorsosubapical margin and less expanded dorsomedially in lateral view, with 4 dorsal ovisensilla and 9 distally slightly increasing in size on slightly convex, ventral margin. Spermathecal capsule brown; introvert depth of duct about 3/5 of capsule height.
