Leptodactylus diedrus Heyer 1994

Smooth jungle frog, Sapito confuso, Wa-wa

Camp V. 19 March 2002. EBRG 4666 (adult male) .

The specimen fits the description of Leptodactylus diedrus given by Heyer (1994b) in lacking dorsolateral folds, having an unpatterned belly, and by the presence of slightly enlarged toe tips lacking discs. It also has a rounded canthus rostralis, large tympanum (about 2/3 diameter of eye diameter), weak fringes on interior edges of FII and FIII, two moderately large black thumb spines, dorsum with many small tubercles (spicules) that are more numerous posteriorly, smooth venter, posteroventral surfaces of thighs areolate, no spines on the chest, fringes well developed on toes, distinct pale metatarsal and tarsal folds, and posterior surfaces of tarsus and plantar surfaces with diminutive tubercles. Heyer (1998) noted that specimens of L. diedrus usually have a groove on the superior part of the expanded toe tip; this is not apparent in EBRG 4666.

Leptodactylus diedrus was reported from Venezuela by a single record from Cerro Neblina ( McDiarmid and Paolillo 1988) as Vanzolinius discodactylus . Heyer (in litt.) subsequently positively identified these specimens (USNM 307105–06) as L. diedrus . Vanzolinius discodactylus is then not yet known from Venezuela. Our specimen was found at the edge of Canaracuni stream at night. Small Leptodactylus are called wa-wa by the Ye’kwanas.
