Diagnosis.

Like Calocosmus robustus , this is a highly polymorphic species with regard to maculations of the head, pronotum, scutellum, and elytron. It is allied with the group of large, robust species that include Calocosmus robustus and Calocosmus melanurus . It is distinguished from Calocosmus melanurus by having the tibiae partially and tarsi completely piceous (the tibiae are completely and the tarsi are at least partially fulvous in Calocosmus melanurus ). The antennae of Calocosmus nigritarsis are nearly completely black with, at most, only the extreme bases of a few antennomeres fulvous ( Calocosmus melanurus and Calocosmus robustus have the antennal fulvous annulations more pronounced). In almost all specimens of Calocosmus nigritarsis , the pronotum has a large, anteromedial black macula (at most a small spot in Calocosmus robustus and absent in Calocosmus melanurus .

Notes.

This species was previously known from only a few specimens. Fieldwork in the Dominican Republic has produced many additional specimens that have better elucidated the level of polymorphism of the elytral and pronotal maculations.
