IdentificationAccording to Dietz (1896), adults of this species are oblong-oval, black, and covered in white scales. The scales are grouped into a scutellar spot (grouping of scales at the base of the thorax and elytra) and a fairly distinct sutural line on the dorsal surface. The antennae have seven funicle (antennal segments between the scape and the clubbed) segments. The first and second of these segments being longer than the third and fourth segments combined. The antennal club is elongate and pointed. The beak is long, slender and curved with some scaling near the base. The tarsi are slender with the second and third segments together being longer than the fourth. The fourth tarsal segment projects less than the length of the third segment. The tarsal claws are also toothed. Length 2.5 - 2.8 mm.
