Leptodactylus riveroi Heyer et Pyburn 1983

Rivero’s white-lipped frog, Sapo-rana rugoso de Rivero, Jujüku

rio-Amorós 1998a). It also occurs in the northern Brazilian and Colombian Amazon ( Heyer and Pyburn 1983; Lynch and Vargas Ramírez 2001). Our specimen has a SVL of 54 mm and it conforms to the original description ( Heyer and Pyburn 1983). The dorsolateral folds are bordered laterally by an indistinct darker gray stripe. The flanks are gray with symmetrical supra axillary black spots. A dark gray canthal stripe begins on the tip of the snout but does not reach the eye. A black supratympanic fold extends from the eye to the rear of the tympanum. A distinct white stripe extends posteriorly to the scapular region from a point below the eye. The venter is white with small brown dots on the throat, and larger spots on the chest and belly (unlike the striking reticulated pattern seen in Rivero 1968). Our specimen was sitting 0.5 m from the edge of Canaracuni stream at night. Medium-sized Leptodatylus are known as jujüku by the local inhabitants.
