Diagnosis. Scutum pale brown, with 4 blackish brown to black, longitudinal stripes; two median ones faded and converged with each other posteriorly; scutellum with blackish brown stripe medially, pale brown laterally (Pl. 2B). Abdominal tergites III‒V each with black, medially widely interrupted, caudal band (Pl. 2B). Setae of middle row on 2nd costal section all heavy, peg-like, present beyond tip of R2+3. Tenth sternite somewhat obovate, with small notch medially on dorsal margin (Fig. 21 D). Oviscapt valve moderately convex dorsosubapically in lateral view (Fig. 21 G).

Description (♂, ♀). Head: Cibarium with 2‒3 medial and 4–7 posterior sensilla per side.

Thorax (Pl. 2B): Postpronotum yellowish brown; pleura blackish brown to black.

Wing (Pl. 2B) pale brown; veins brown. C1 bristle 2, subequal. Haltere pale yellow.

Legs: (P1. 2B)Hindleg tibia without black, apically blunt, stout spines at outer apex on underside.

Abdomen: Sternites grayish yellow; male VI somewhat quadrate, slightly wider than long.

Male terminalia (Fig. 21 A −F): Epandrium pubescent posteriorly on dorsal 1/3 and sparsely on median portion, ventrally with 11 long setae; caudoventral portion somewhat rounded apically, with ca. 30 short, stout setulae. Surstylus with 1 seta in addition to 2 stout, upturned prensisetae around caudodorsal corner, 7 apically converging prensisetae along distal margin and 1 short seta near ventral apex. Cercus largely pubescent except for posterior to ventral portion, with 28−30 long setae. Hypandrium long, largely parallel-sided, with apodeme on anterior margin. Gonopod apically curved ventrad, hook-like in lateral view. Paramere auricular, slightly convex at dorsomedian edge, not longer than twice of width, with 5 sensilla. Aedeagal basal process slightly longer than 1/2 length of paramere.

Female terminalia (Fig. 21 G, H; Pl. 6J): Oviscapt valve slightly wider than 1/2 of its length, less expanded dorsomedially in lateral view, with 2 dorsal ovisensilla on convex, dorsosubapical margin, 7 lateral ones and 9 distally increasing in size on nearly straight, ventral margin. Spermathecal capsule brown; introvert depth of duct about 1/2 of capsule height.
