Bani is a town situated on the coastal plain where the Cordillera Central terminate along the southcentral coast of the Dominican Republic. Exactly where the type series for this species originated previously has been uncertain as Mandl did not present a specific locality other than Bani nor have any other specimens of this species been collected subsequent to the original type series. However, refer to the discussion under its Ecology below for circumstantial evidence as to the most likely collection site to help establish the type locality for this species at the coordinates shown above.</paragraph>

The town of Bani lies in the coastal plain on the southcentral coast of the Dominican Republic. The Rio Bani emerges from the southeastern end of Cordillera Central and flows along the eastern edge of the town. This species likely occurs elsewhere along the Rio Bani further southward toward the coast and northward into the Cordillera Central.</paragraph>

, new species, are the only species on Hispaniola with an elytral pattern of shiny, white markings with all lunules wide, complete and boldly contrasting with the darker, background color in most specimens examined. Despite this superficial similarity, there seems little doubt that these two species are distinctive based on differences in the form of the sclerites within the aedeagus of males of each species. A comparison of the other morphological characters presented in the key and the descriptions for each species further support their distinctiveness. These two species also appear to be allopatric based on the limited collection data currently available. However, additional collecting may change our understanding of their allopatry. Despite this distinctiveness as separate species and apparent allopatry, it is interesting to note that these two species seem to occupy a similar habitat type along the flood plains of major rivers flowing from the southeastern end of the Cordillera Central in Peravia Province, Dominican Republic. In these flood plain

, both species appear to have developed different habitat requirements from other species on Hispaniola. Their limited geographic distributions in close proximity to each other, and their similar requirements for low elevation habitats, may be the result of a common lineage.
