status

 

Distribution. Tomarus adoceteus is known only from Grand and Little Cayman Islands.

Diagnosis. Tomarus adoceteus is distinguished from other Tomarus species by the bidentate mandibles, simple protarsus in the males, first elytral interval sparsely punctate, apex of the metatibia with about ten short spinules, and form of the male parameres which are especially distinctive. While other species may have parameres with one or two character states of narrow form, long tooth projecting laterally at the midpoint of the shaft, or narrowly elongated apex, none have this combination. This species is also slightly larger than the other three species of Tomarus that occur in the West Indies, and is the only one of the Caribbean species with bidentate, as opposed to tridentate, mandibles.
