Head anteriorly shiny, sparsely punctulate, slightly alutaceous behind. Frons separated by 3 x the width of scape. Rostrum 0.74-0.77 x the length of prothorax, straight, depressed; postrostrum moderately punctate on either side, with a sulcus against scrobes; prerostrum a little wider than long, indistinctly punctate. Scape extending to about anterior third of eyes, weakly to distinctly compressed; funicle with segment 2 shorter than 1, shorter than 3 + 4; club as long as preceding six segments combined.
