( Fig. 49 View FIGURE 49 ; Pl. 5F; Pl. 7P)

Diagnosis. Male abdominal sternite VI wider than long. Tenth sternite much narrowing ventrally, nearly flat on dorsomedial margin ( Fig. 49 View FIGURE 49 D). Paramere strongly curved dorsad in lateral view ( Fig. 49 View FIGURE 49 F). Hypandrium convex on lateral margins and slightly narrowing anteriorly in dorsal/ventral view ( Fig. 49 View FIGURE 49 E). Oviscapt valve with 5 dorsal ovisensilla ( Fig. 49 View FIGURE 49 H).

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

Male terminalia ( Fig. 49 View FIGURE 49 A −F): Epandrium pubescent except for dorsocentral, antero- and ventromarginal portions, with ca. 12 long setae on ventral half and with ca. 8 shorter setae on caudoventral portion. Surstylus with 1 thick seta in addition to 2 stout, upturned prensisetae at and above caudodorsal corner and 5 prensisetae along distal margin. Cercus with ca. 10−23 long setae. Paramere with 6 sensilla: distalmost one distantly located. Aedeagal basal process distally less expanded in lateral view, about 3/5 length of paramere.

Female terminalia ( Fig. 49 View FIGURE 49 G, H; Pl. 7P): Oviscapt valve with 11−13 lateral and 6−7 ventral ovisensilla. Spermatheca capsule pale brown; introvert depth of duct about 1/4 of capsule height.
