Female genitalia.

Abdominal sternite VII (Fig. 26), in ventral view, broader than long; anterior margin straight; posterior margin well produced medially, sometimes forming two distinct lateral lobes; lateral margins convergent posteriorly; surface with few small setae mostly on basal half. Internal sternite VIII not forming sclerites. Pygofer (Fig. 27), in lateral view, slightly produced posteriorly; posterior margin with subacute apex; surface with macrosetae on posterior portion and extending anteriorly along ventral margin, attaining midlength. Valvifers I, in lateral view (Fig. 28), nearly rectangular, slightly expanded posteriorly, posteroventral margin angulate; in ventral view (Fig. 34), forming lobes (LB) articulating with valvulae I. Valvifers II (Fig. 29), in lateral view, nearly fusiform, with small group of clustered setae near articulation point (AP). Valvulae I of ovipositor, in ventral view (Fig. 34), with base gradually broadening posteriorly; in lateral view (Fig. 30), shaft distinctly curved dorsally and with dorsal margin concave, with ventral hyaline area (VHA) near apex; dorsal sculptured area located on apical half, broadening to near apex and gradually narrowing to apex, formed by dense scale-like processes; ventral sculptured area restricted to apical portion, formed by dense imbricate processes; ventral interlocking device (VID) distinct on basal 2/3 of shaft; apex of shaft acute. Valvulae II of ovipositor (Figs 31 and 32), in lateral view, slightly expanded beyond basal curvature, distinctly curved dorsally and with dorsal margin concave; apex narrowly rounded; preapical prominence (PP) indistinct; shaft bearing approximately 4-6 teeth (TO) distributed on apical half behind basal curvature; each tooth semiround and bearing few denticles (DE) or not bearing denticles; denticles mostly distributed on dorsal margin of shaft between teeth and on dorsal and ventral margins of apical portion, dentate dorsal margin longer than ventral margin; ducts extending toward dorsal margin and toward apical portion of shaft. Gonoplacs (Fig. 33), in lateral view, with basal half narrow and apical half distinctly expanded; apex rounded.
