Genus Bythocrotus Simon, 1903

Medium sized spiders. Dull in color. Carapace is broad and high. Tibia of the male palp is widened and armed with multiple short and stout macrosetae. Palpal bulb is usually small with short and slightly curved embolus. Tegulum lacks distinct proximal lobe. Epigynum has window with a narrow median septum. Vulva has a pair of secondary spermathecae in addition to the primary spermathecae. Bythocrotus can be easily distinguished from other Caribbean euophryine genera by the unique male palpal structure.

Only the type species, Bythocrotus cephalotes (Simon) (see Bryant 1943) has been reported from Hispaniola. A new species from the Dominican Republic is described here.
