( Fig. 38 ; Pl. 4C; Pl. 7E) Diagnosis. Abdominal tergites II‒VI with blackish brown to black, caudal bands broadened laterally and medially widely interrupted or constricted (Pl. 4C). Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside. Tenth sternite longer than wide, dorsally slightly dilated, with shallow, somewhat quadrate notch medially on dorsal margin ( Fig. 38 D). Description (♂, ♀). Head: Cibarium with 3−5 medial and 4−5 posterior sensilla per side. Labellum with 6 pseudotracheae per side. Thorax (Pl. 4C): Postpronotum yellowish brown; scutum yellowish brown along notopleural line, transverse suture, lines connecting anterior and posterior, dorsocentral setae, leaving medial portion as large, black macula: scutellum black, marginally yellowish brown; pleura yellowish brown to blackish brown. Wing (Pl. 4C) infuscate; veins brown. C1 setae 2, subequal. Haltere knob pale yellow; stem somewhat pale brown. Legs (Pl. 4C) yellow. Abdomen: Sternites grayish yellow. Male terminalia ( Fig. 38 A–F): Epandrium pubescent posteriorly on subdorsal to medial portion, with ca. 16 long setae on ventral half and ca. 11 shorter setae on caudoventral portion. Surstylus with 3 long setae in addition to 2 stout, upturned prensisetae around to above caudodorsal corner, 6 prensisetae along distal margin and 2 setae near ventral apex. Cercus unpubescent, with ca. 25 long setae. Hypandrium posteriorly slightly widened in ventral view and strongly convex in lateral view, roundish on anterior margin. Gonopod long, protruded ventrad apically. Paramere slightly bent ventrad in distal 1/3 portion, with 6 sensilla. Aedeagal basal process slightly longer than 1/2 length of paramere. FIGURE 38.
