Usually the head is a little wider than the pronotum . The pronotum is narrow, heart-shaped. The neck shield angle is a little less than 90 °. Very dense, even fine hairs are present on the elytra. The head and pronotum are only slightly hairy, but the temples are clearly visible. The 3 anterior tarsi of the males are weakly enlarged. Its 7th sternite is deeply cut in the middle of the rear margin .
