P. centralis is the largest species. A male and two females of this species from Trinidad weighed 14.4-17.2 grams.
Coloration is drab brown to glossy black above and somewhat paler below.
The short, broad skull, with its strongly domed palate, in combination with certain dental features, is characteristic. The members of this genus do not seem to be as gregarious as some of the other molossid bats. Colonies of approximately half a dozen individuals have been found roosting in hollow trees and on the underside of palm leaves. As far as is known, the diet consists of insects.
