Abstract
We describe and name a new species of Noblella Barbour, 1930 (Strabomantidae) from southern Peru. Key diagnostic characteristics of the new species include the presence of a short, oblique fold-like tubercle on the ventral part of the tarsal region, two phalanges on finger IV, and an evident tympanum. The elevational distribution of the new species spans 1250 m (240–1490 m) from lowland Amazon rainforest to montane forest on the eastern slopes of the Andes.
Keywords: amphibians; ecomorphology; miniaturization; systematics; taxonomy

Noblella losamigos sp. n.
Diagnosis: A new species of Noblella characterized by (1) skin on dorsum smooth to finely shagreen, skin on belly smooth, discoidal fold absent, dorsolateral folds absent; (2) tympanic annulus visible below skin, with the upper portion (1/4) covered by a supratympanic fold; tympanic membrane evident; columella present (Figure 6); (3) snout short, rounded in dorsal view and bluntly rounded to subtruncate in profile; (4) upper eyelid with minute tubercles, cranial crests absent; (5) dentigerous process of vomers absent; (6) vocal slits present; nuptial pads absent; ....
Etymology: The specific epithet is a toponym used in apposition and it refers to the type locality. Los Amigos Biological Station is located next to Los Amigos Conservation Concession, on the lower Los Amigos River watershed. Both the station and the conservation concession were established by the Amazon Conservation Association, which is a nonprofit organization that (along with its Peruvian counterpart, Conservación Amazónica—ACCA) promotes scientific research, education, and conservation in the western Amazon.
