TAXONOMIC STATUS: At least four species of the subgenus Thoracobombus from Central and South America have many individuals for which the pubescence is almost entirely black. The genitalia of the males are quite distinctive, but association of the conspecific females with these males has caused problems.
DISTRIBUTION: N Neotropical, W Neotropical Regions.
