Spintherophyta

Body oval, convex in lateral view, ventral outline flat. Head alutaceous, glabrous, deeply coarsely punctate; frons coarsely punctured, less densely than vertex; clypeus punctured like vertex, widely shallowly emarginate. Antennomere 2 about equal in length and width, much narrower and shorter than antennomere 1, glabrous; antennomeres 3–6 sparsely pubescent, subequal in length; antennomeres 7–11 densely covered with very short pubescence and a few longer setae, each about as long as broad, about twice as broad as antennomeres 2–6. Pronotum about twice as wide as long, nearly as wide posteriad as distance across elytral base, arcuately narrowed to anterolateral corners; discal surface distinctly alutaceous, densely and deeply punctate, punctures larger than those of frons or vertex but smaller than those of elytra. Elytra slightly broader at base than posterior portion of prothorax, of uniform width until curving inward towards apex; punctures next to suture large, seriate, separated by distance equal to about half width of puncture; remaining punctures larger, separated by distance less than a quarter width of puncture. Ventral areas black, not metallic, glabrous, entirely impunctate except prosternum. Abdominal ventrites each with one or two long, centrally located setae. Legs with tibiae setose, bearing dorsal, lateral, and ventral carinae. Aedeagus in dorsal view broad in basal fourth, narrowed in middle third, broad near distal fourth, with apical fifth gradually narrowed to bluntly pointed tip.
