Diagnosis. Patch of dense, small setae or stout setulae absent on caudoventral portion of epandrium (Fig. 5 A). Common characters. Cibarium with 2−3 posterior sensilla slightly curved anteriad per side: anteromost one twice as long as posteromost, medial sensillum. Postpronotum blackish brown to black; scutum and scutellum unicolorously dark brown to black; pleura blackish brown to black (Pl. 5E, F). Wing hyaline, slightly infuscate (Pl. 5E, F); veins dark brown; C1 setae 2, subequal; setae of middle row on 2nd costal section of wing all heavy, peglike, reaching or beyond tip of R2+3. Haltere pale yellow. Legs yellowish brown to yellow (Pl. 5E, F); hindleg tibia without black, apically blunt, stout spines at outer apex on underside; hindleg tarsomeres I‒IV each with 1 such spine at outer apex on underside. Abdominal tergites unicolorously dark brown to black (Pl. 5E, F); sternites grayish brown. Epandrium largely pubescent (Figs. 48 A, 49A). Surstylus deeply concave on ventral 2/3 of distal margin, with 2 setae near ventral apex. (Figs. 48 C, 49C). Cercus pubescent on anteromedial portion (Figs. 48 A, 49A). Gonopod narrow, apically connecting to aedeagal basal process by narrow, membranous tissue (Figs. 48 F, 49F). Paramere more or less roundish on apical margin in lateral view, longer than twice of width (Figs. 48 F, 49F). Aedeagal basal process longer than 1/2 length of paramere (Figs. 48 E, 49E). Oviscapt valve horizontally expanded at apical portion, less expanded in dorsomedial portion, gently curved on dorsosubapical margin, convex on ventral margin in lateral view, with lateral ovisensilla tightly arranged in nearly straight (in ventral view) row on margin of apicolateral flap and nearly equal-sized, ventral ones arranged entirely at nearly equal intervals; subapical, trichoid ovisensillum stout, longer than apical, peg-like ovisensillum (Figs, 48G, H, 49G, H). Spermathecal capsule wider than long, apically nearly flat (Pl. 7O, P).
