Material examined. Field observations; (13°25′20″S, 069°36′36″W), 27–28.IX.2013.

Identification. A large leptodactylid species, SVL 100– 195 mm in males and 115–181 mm in females. It can be identified by smooth dorsum with continuous dorsolat- eral folds from eyes to groin; dorsum uniform grayish brown with 1 or 2 narrow transversal bands.

Similar species in neighboring localities are: L. knudseni , which differs by having dorsolateral folds extending to the sacrum, venter uniform gray, males with spines on chest and thumbs; L. stenodema , which is smaller, SVL <100 mm and its dorsolateral folds originate posterior to tympanum ( Duellman 1978, 2005, W. R. Heyer 1979, 2005, Rodriguez and Duellman 1994, M. Heyer et al. 2012, de Sá et al. 2014).

Distribution. Leptodactylus pentadactylus is widely distributed in the Amazonian forests in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suri- name and Venezuela (de la Riva et al. 2000, M. Heyer et al. 2012, Cole et al. 2013, Frost 2019).
