( Fig. 43 View FIGURE 43 ; Pl. 4H; Pl. 7J)

Diagnosis. Abdominal tergites unicolorously glossy black (Pl. 4H). Labellum with 6 pseudotracheae per side. Tenth sternite longer than wide, dorsally dilated, concave on lateral margins ( Fig. 43 View FIGURE 43 D). Oviscapt valve with 4 dorsal ovisensilla ( Fig. 43 View FIGURE 43 G).

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

Thorax (Pl. 4H): Postpronotum blackish brown to black; pleura blackish brown to black.

Wing (Pl. 4H) pale brown; veins brown. C1 setae 2, subequal. Haltere pale yellow.

Legs (Pl. 4H) yellowish brown. Hindleg tarsomere I with 2 black, apically blunt, stout spines at outer apex on underside.

Abdomen: Sternites grayish brown.

Male terminalia ( Fig. 43 View FIGURE 43 A −F): Epandrium densely pubescent except for anterior and ventral 1/3 portions, with ca 15 long setae on ventral half and ca. 16 shorter setae on caudoventral portion. Surstylus with 1 seta in addition to 1 stout, upturned prensiseta above caudodorsal corner, 7 prensisetae along distal margin and 1 seta at ventral apex. Tenth sternite with W-shaped notch medially on dorsal margin. Cercus sparsely pubescent on anterior portion, with ca. 26 long setae. Hypandrium somewhat trapeziform, posteriorly broader. Gonopod apically more or less obtuse in lateral view. Paramere smooth on dorsal and ventral margins, with 5 sensilla. Aedeagal basal process slightly shorter than 1/2 length of paramere.

Female terminalia ( Fig. 43 View FIGURE 43 G, H; Pl. 7J): Oviscapt valve brown, obliquely truncate on dorsosubapical margin in lateral view, with 13 ventral ovisensilla arranged entirely at nearly equal intervals. Spermathecal capsule brown; introvert depth of duct about 4/5 of capsule height.
