Adult antennae are pale reddish-brown and two thirds of the body in length, with the basal annulus more than twice the length of the second annulus. Both the vertex of the head and frons are deep reddish-brown with a black suture and pale warts. The process on segment 10 of males is visible. The process is long and thin, it curves dorsally and narrows to a point (Nimmo, 1974).
