( Fig. 36 View FIGURE 36 ; Pl. 4A; Pl. 7C)

Diagnosis. Abdominal tergite I grayish yellow; II −VI yellow, each with broad, black, caudal band; bands on II − IV medially narrowly interrupted or constricted; bands on V and VI medially neither interrupted/constricted nor protruded (Pl. 4A). Hindleg tarsomere I with 1 black, apically blunt, stout spine at outer apex on underside. Labellum with 5 pseudotracheae per side. Tenth sternite broader than long, dorsally dilated, with V-shaped notch medially on dorsal margin ( Fig. 36 View FIGURE 36 D). Paramere slightly serrated on dorsosubacpial margin ( Fig. 36 View FIGURE 36 F). Hypandrium slightly narrowing posteriorly ( Fig. 36 View FIGURE 36 E).

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

Thorax (Pl. 4A): Postpronotum yellowish brown; scutum black, narrowly pale along lines passing ipsilateral dorsocentral setae; scutellum black, pale laterally; pleura blackish brown to black.

Wing (Pl. 4A) pale brown; veins brown. C1 setae 2, subequal. Haltere knob yellow; stem grayish yellow.

Legs (Pl. 4A) yellowish brown.

Abdomen: Sternites grayish yellow.

Male terminalia ( Fig. 36 View FIGURE 36 A −F): Epandrium unpubescent, with ca. 28 long setae on ventral half: caudoventral ones shorter and more densely distributed. Surstylus with 2 thick setae in addition to 1 stout, upturned prensiseta around caudodorsal corner, 6 prensisetae along distal margin and 2 setae near ventral apex. Cercus unpubescent, with ca. 25 long setae. Hypandrium slightly narrowing posteriorly, slightly concaved on medial portion of ventral surface in lateral view. Gonopod well developed. Paramere with 7 sensilla. Aedeagal basal process about 2/5 length of paramere.

Female terminalia ( Fig. 36 View FIGURE 36 G, H; Pl. 7C): Oviscapt valve yellowish brown, obliquely truncate on dorsosubapical margin in lateral view, with 4 dorsal ovisensilla and 16−19 ventral ones arranged entirely at nearly equal intervals. Spermathecal capsule brown; introvert depth of duct about 4/5 of capsule height.
