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.
