Redescription.
Length 6-8 mm.
Head
: punctures separated by ≤ 1 diameter. Mentum midportion broad, concealing lateral wings, midportion without distinct median carina.
Prothorax
: pronotum punctate, punctures closely spaced, separated by ~1 diameter. Hypomeron very lightly textured, without clear punctation. Prosternal process produced between forecoxae.
Pterothorax
: elytra width about equal to pronotal width. Elytral striae and intervals punctate; striae impressed. Interval punctures fine, closely spaced (~1 diameter), distinctly smaller than strial punctures. Elytral tubercles present on apical declivity.
Abdomen
: ventrite V sulcus narrowly separated from apical border.
Terminalia
: male: parameres converging apically, fused basally with deep and wide opening at apex exposing median lobe (Fig.
4C
). Female: ovipositor slightly elongate (ratio of ovipositor coxites I-IV to paraprocts <1:1). Bursa copulatrix bilobate, accessory gland present near-to spermatheca, accessory pouch absent.
Distribution.
Zimbabwe.
