Head as long as rostrum, upper surface flat or even, with shallow, confluent punctations, usually hidden behind vestiture. Rostrum plain dorsally, as long as broad, anterior margin 0.83x as broad as posterior margin; median furrow short, broad; lateral carinae distinct; sides straight; scrobes 2x broad as breadth at posterior margin and squarish anteriorly but narrow and convergent posteriorly. Eyes dorsolateral, slightly or moderately convex, length: breadth ratio 2.66:1 (figs. 18 and 50). Antennae dark brown; scape abruptly clavate; funicle with first segment 1.16x as long as second, third and fourth subequal, fifth and sixth equal and bead like; club conical (fig. 76).
