A new species of the weevil genus Mecysmoderes from southern India (Coleoptera: Curculionidae)

Mecysmoderes (Coeliosomus) alexanderi sp. n. is described from southern India. The new species differs from other members of the subgenus Coeliosomus in the strongly widened apically tibiae with elongate apical combs composed of sparse stout spines, nearly straight rostrum, more strongly convex dorsally elytra with regularly granulate intervals, and in the presence of a sharp tooth on the inner surface of hind tibia one-third way from apex in male. The structure of the head, with a sharp although shallow depression separating the frons from vertex, is apparently unique in the genus.
