Material examined. MUSA 4918, 4920; (13°25′20″S,

069°36′36″W), 28.IX.2013. MUSA 4919; Transect TN2, 28.IX.2013.

Identification. A moderate sized leptodactylid species, SVL 54–79.4 mm in males and 55.8–90 mm in females. It can be identified by dorsum smooth with scattered tuber- cles, and prominent tubercular dorsolateral folds extending at least to the sacrum. Breeding males have 2 nuptial spines on each thumb and a pair of spines on the chest. Dorsum brown with dark brown spots; venter grayish cream with light cream marks. Upper lip cream with irregular dark brown blotches. Posterior thighs cream with black mottling. Similar species in adjacent localities are: L. rhodomystax , which lacks dorsal tubercles and upper lip is uniformly cream; L. bolivianus , which has smooth and continuous dorsolateral folds (W. R. Heyer 1979, Rodriguez and Duellman 1994, Duellman 2005, de Sá et al. 2014).

Distribution. Leptodactylus rhodonotus is distributed on the Andean slopes and the lowlands of the upper Amazon Basin of Bolivia and Peru, from 200 to 2050 m a.s.l. (W. R. Heyer 1979, de la Riva et al. 2000, de Sá et al. 2014, Frost 2019).
