(Fig. 28; Pl. 3A; Pl. 6P)
Diagnosis. Setae of middle row on 2nd costal section all weak, trichoid. Hindleg tibia without black, apically blunt, stout spine at outer apex on underside. Male abdominal sternite VI large, somewhat quadrate, slightly wider than long, concave on posterior margin. Tenth sternite 2/5 as wide as long, concave on lateral margins, medially projected on dorsal margin (Fig. 28 D). Oviscapt valve distally slightly narrowing in ventral view: apicolateral flap less developed (Fig. 28 H).
Description (♂, ♀). Head: Cibarium with 2−3 medial and 4 posterior sensilla per side.
Thorax (Pl. 3A): Postpronotum dark brown; scutum and scutellum glossy black; pleura dark brown to blackish brown.
Wing (Pl. 3A) pale brown; veins brown. C1 setae 2, subequal. Haltere pale yellow.
Legs (Pl. 3A) yellowish brown.
Abdomen (Pl. 3A): Tergites glossy black. Sternites grayish yellow.
Male terminalia (Fig. 28 A–F): Epandrium pubescent on dorsal portion, ventrally with ca. 15 long setae; caudoventral portion apically roundish, with ca. 30 short, stout setulae. Surstylus with 2 setae in addition to 2 stout, upturned prensiseta around to above caudodorsal corner, 5 apically converging prensisetae along distal margin and 3 short setae near ventral apex. Cercus sparsely pubescent on anterior portion, with ca. 22 long setae. Hypandrium somewhat trapeziform, wider posteriorly. Gonopod somewhat triangular, pointed apically in lateral view. Paramere distally somewhat triangular in lateral view, not longer than twice of width, with 8 sensilla. Aedeagal basal process slightly longer than 1/2 length of paramere.
Female terminalia (Fig. 28 G, H; Pl. 6P): Oviscapt valve gently curved on dorsosubapical margin and less expanded dorsomedially in lateral view, with 5 dorsal ovisensilla, 10 lateral ones in a slightly convex (in ventral view) row on apicolateral portion and 9−10 distally slightly increasing in size on nearly straight, ventral margin. Spermathecal capsule brown; introvert depth of duct about 3/5 of capsule height.
