( Fig. 27 ; Pl. 2H; Pl. 6O) 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. Abdomen (Pl. 2H): Tergite I dark brown; II yellowish brown, with broad, black caudal band medially interrupted. Sternites pale grayish brown; male VI posteriorly wider, concave on posterior margin. 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.
