Calocosmus semimarginatus Bates Fig. 9d

Diagnosis.

This small, slender species is most similar to Calocosmus fulvicollis Fisher, a Cuban species, in that it has nearly uniformly dark elytra with a fulvous suture. Fisher (1925) suggested that Calocosmus fulvicollis could be a synonym of Calocosmus semimarginatus , however, the head is dark in Calocosmus fulvicollis but light in Calocosmus semimarginatus and the antennae are all black in Calocosmus fulvicollis but at least antennomeres 4-5 are fulvous annulate at the base in Calocosmus semimarginatus . Among the Hispaniolan species, Calocosmus semimarginatus is most similar to Calocosmus nigripennis , but is easily distinguished by having the elytral suture pale colored and the pronotum not transversely bisulcate.

Notes.

The first male specimen of this species was found in the FSCA collection. This species, formerly known only from Cuba, is here recorded for the Dominican Republic and Hispaniola (new country and island records).
