Distribution. Cuba, Hispaniola, Puerto Rico. Captured during May, June, July, August- September from sea level- 1150 m in elevation in Azua, Barahona, La Altagracia, Hato Mayor, and Pedernales provinces in the Dominican Republic.

Remarks. Andrenosoma chalybeum is distinguished by the bluish-black ground color and the straight proboscis with an obtuse apex ( Fisher, 1986). All specimens examined from the Dominican Republic and Puerto Rico fit the description of this species and is the first record of the species in the former location. Yet at least three size groups exists and probably represent different species. The series from the Dominican Republic consist of two distinct size groups, one moderately large and the other much smaller. Furthermore, the specimens from Puerto Rico are much larger than any of those from the Dominican Republic. Specimens from the Dominican Republic were captured on follen trees at or near sea level in moist, deciduous forests in Azua, Barahona, La Altagracia, Hato Mayor, and Pedernales provinces of Dominican Republic and in Puerto Rico.
