( Fig. 40 ; Pl. 4E; Pl. 7G) Diagnosis. Abdominal tergite IV with caudal, black band medially neither interrupted/constricted nor protruded (Pl. 4E). Scutum and scutellum unicolorously glossy black, without distinct color pattern (Pl. 4E). Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside. Tenth sternite slightly broader than long, dorsally dilated, with deep, narrow, V-shaped notch medially on dorsal margin ( Fig. 40 D). Oviscapt valve with 4‒5 dorsal ovisensilla ( Fig. 40 H). Description (♂, ♀). Head: Cibarium with 2 medial and 4‒5 posterior sensilla per side. Labellum with 6 pseudotracheae per side. Thorax (Pl. 4E): Postpronotum blackish brown; thoracic pleura blackish brown. Wing (Pl. 4E) grayish brown; veins brown; C1 setae 2, subequal. Haltere pale yellow. Legs (Pl. 4E) yellow. Abdomen (Pl. 4E): Tergites yellowish brown, with broad, black, laterally broadened, caudal bands on II −V; bands on II and III medially narrowly interrupted; VI entirely blackish brown. Sternites grayish yellow. Male terminalia ( Fig. 40 A −F): Epandrium sparsely pubescent on posterior portion of dorsal half, with ca 10 long setae on ventral half and ca. 15 shorter setae on caudoventral portion. Surstylus with 2 long setae in addition to 2 more or less stout, upturned prensisetae at and above caudodorsal corner, 6 prensisetae along distal margin and 1 seta at ventral apex. Cercus slightly pubescent on anterior portion, with ca. 23 long setae. Hypandrium nearly parallel-sided, roundish on anterior margin, posteriorly convex in lateral view. Gonopod broad, apically somewhat triangular and curved ventrad in lateral view. Paramere apically somewhat truncate, with 7 sensilla. Aedeagal basal process about 1/2 length of paramere. FIGURE 40.
