SUBFAMILY PSELAPHINAE , theant-like mold beetles

These small beetles, formerly considered to be a family of their own, live in forest leaf litter or rotted logs and feed on mites, Collembola, and other very small invertebrates. The West Indian fauna is very poorly known. Park et al. (1976) is the last treatment of the West Indian fauna. Much of the genus level fauna of the West Indies occurs in Mexico . See Navarrete-Heredia et al. (2002) for keys for generic identification of that fauna. New taxa records and new island records are from identifications courtesy of D. Chandler.
