(Fig. 47; Pl. 5D; Pl. 7N)

Diagnosis. Tergites II −VI with broad, blackish brown to black, caudal bands; bands on II −IV medially narrowly interrupted/constricted; band on V medially neither interrupted/constricted nor protruded (Pl. 5C). Thorax maculated by central, broader and 2 lateral, narrower dark, longitudinal stripes on pale brown ground: central stripe running through pronotum and scutum, but lateral stripes shorter, interrupted by transverse suture (Pl. 5D). Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside. Tenth sternite longer than wide, distally somewhat roundly dilated, with shallow, median notch on dorsal margin (Fig. 47 D). Oviscapt valve not dilated subbasally in ventral view, only slightly concave on ventral margin and gently curved on dorsosubapical margin in lateral view, with 4−5 dorsal ovisensilla and 18−19 ventral ones arranged entirely at nearly equal intervals (Fig. 47 G, H).

Description (♂, ♀). Head: Cibarium with 3−4 medial and 5−6 posterior sensilla per side. Labellum with 6 pseudotracheae per side.

Thorax (Pl. 5D): Postpronotum yellowish brown; scutellum medially blackish brown, marginally yellowish brown; pleura brown to blackish brown.

Wing (Pl. 5D) pale brown. C1 setae 2: ventral one shorter and thinner. Haltere pale yellow.

Legs (Pl. 5D) yellowish brown.

Abdomen: Sternites grayish yellow.

Male terminalia (Fig. 47 A −F): Epandrium broad, truncate on ventral margin, only very sparsely pubescent, with ca. 15 long setae on ventral half and ca. 18 shorter setae on caudoventral portion. Surstylus with 1 long, thick seta in addition to 2 stout, upturned prensisetae around caudodorsal corner, 7 prensisetae along distal margin and 1 seta at ventral apex. Cercus very sparsely pubescent, with ca. 25 long setae. Hypandrium obovate. Gonopod narrow, protruded ventrad in lateral view. Paramere with 6 sensilla: distalmost one distantly located from others. Aedeagal basal process about 1/2 length of paramere.

Female terminalia (Fig. 47 G, H; Pl. 7N): Spermathecal capsule brown; introvert depth of duct about 4/5 of capsule height.
