Description
The head, including the eyes, is narrower than the base of the mesonotum and almost as long as the pronotum. The forehead is obliquely depressed. The distance between the ocelli
A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish the ...
and the eyes is greater than the space between them, which has a broad and strong longitudinal groove.[
The pronotum is clearly shorter than the mesonotum, moderately convex in laterality with a coarsely serrated margin. The posterior margin is moderately wide and has truncated lateral angles. The operculum in the male is short and wide, extending beyond the base of the metasternum. The anterior femora are strongly spiny below. The rostrum reaches the base of the metasternum. Both pairs of wings are semi-opaque, with the forewings containing eight apical cells.][
