Aulacizes obsoleta Melichar 1926

Diagnosis. Crown, pronotum and scutellum light brown, with longitudinal dark line on disc of pronotum; forewings brown with yellow veins; base of clypeus and clypellus dark.

Female terminalia. Abdominal sternite VII, in ventral view ( Fig. 4 ), with lateral margins slightly convergent posteriorly, posterior margin emarginate with a slight convex median process within emargination; surface with setae distributed throughout disc. Pygofer, in lateral view, moderately produced posteriorly; surface with a few macrosetae mainly in posterior half. First valvifers, in lateral view, ovoid; with small spiniform processes on ventral region. First ovipositor valvulae, in lateral view, slightly broadened beyond basal curvature; dorsal sculptured area formed mostly by scale-like processes arranged in oblique lines; ventral sculptured area formed mostly by linear processes; apex obtuse with dorsal margin slightly concave ( Fig. 16 ), and denticles on ventral and dorsal margins. Second valvulae, in lateral view, broadened beyond basal curvature; dorsal margin of blade bearing 40 to 43 not continuous teeth, each tooth triangular with denticles on posterior margin ( Fig. 28 ); ducts not reach the teeth; apex rounded ( Fig. 40 ), with denticles on dorsal and ventral margins; preapical ventral prominence small but distinct. Gonoplacs, in lateral view, with small basal spiniform processes; scattered microsetae on ventral margin and a few strong setae on apical portion; apex rounded.
