Japanese Cedar Longhorn Beetle
Japanese Cedar Longhorn Beetle (Callidiellum rufipenne Motschulsky) - Adults of C. rufipenne are moderate sized, robust, somewhat depressed, and 6-13 mm long. They have hardened anterior wings (or elytra) that are coarsely punctate. The male is black with reddish humeri ( based at angles or shoulders of the elytra); the female has reddish or testaceous elytra. They can be distinguished from the related genus Semanotus by the principal segment of the legs (femora) being strongly and gradually thickened toward the tip, by the antennae being slender and cylindrical with the second segment elongated, by the dorsal surface of the prothorax (pronotum) being weakly or sparsely punctate, and by the pronotum having a pair of feebly developed and thickened elevations or swellings (callosities), one on each side of the midline.
