This species seems to live in the Southeastern states and the Caribbean. It was also introduced accidentally to the Galapagos Islands. The second link states: "Bell (1985) remarked that what we call Pentagonica flavipes may actually be 'a complex of sibling species, differing only in the form of the male genitalia.' These beetles are regular visitors to lights."
