Description. Length 2.5–3.0 mm, width 1.5–2.0 mm. Body and appendages lacking broader scales except for patches of white scales on scutellum, top of mesepimeron, posterolateral corner of metasternum. Antenna with antennomere 1 of funicle almost as long as remaining six antennomeres. Rostrum laterally with large, deep punctures basal to point of antennal insertion, which is at about apical 2/5, punctures smaller and shallower beyond point of antennal insertion in female, less so in male. Pronotum broad, convex uniformly moderately deep widely spaced punctures, the distance between punctures at least the size of an individual puncture. Elytra very slightly wider than width pronotum at base, similarly broad and convex, striae indicated by large, deep punctures but not impressed, each interstria with a row of minute shallow punctures, base of interstria 3 with small raised swelling. Profemora with two teeth, larger basal tooth simple, rather slender, about 3–4 times larger than smaller more apical tooth, bases of teeth widely separated; metatibia at inner margin with small apical tooth in female, tooth slightly larger in male. Aedeagus straight in lateral view, in dorsal view widest at base, tapering evenly to rounded tip, endophallus simple, with no visible internal sclerotization. Female not dissected.
