Way of life.

Size range - 4.0 mm to 4.9 mm; these beetles are somewhat ubiquitous. They occur near water or at damp places, on a variety of soil types. Adults of all species are dark, often black, and one new species from Paraguay is vividly metallic. Adults of another new species from Perú was found readily under clumps of cut grass in an open field, as well as on algae covered sandy clay running in the bright sunshine. Adults are attracted to lights.

Distribution.

Southern United States south to southern Brazil, including some Caribbean islands.

Notes.

Currently, four described species are assigned to this genus; however, two additional new species are represented in the NMNH collection. A taxonomic revision of the group is needed. Identification of species is impossible without recourse to types.
