The Paraguana common mustached bat is a small cave-roosting bat recorded only on the Paraguana Peninsula of Venezuela. Three caves on the peninsula are its only known daytime refuges.
The body is about 5.8–6.8 cm long, with a forearm of about 5.3–5.6 cm. It has long, pointed ears and long whiskers. The back is pale brown and the underside grayish; a broad fold and small rounded bumps mark the lower lip.
It roosts in caves by day and feeds on insects. The account describes constant-frequency echolocation as an adaptation for catching insects in forest environments.
