A new species of the genus Noblella (Amphibia: Strabomantidae) from Ecuador, with new information for Noblella worleyae

Abstract

We describe a new species of terrestrial-breeding frog of the genus Noblella from the northwestern slopes of the Andes of Ecuador, in the province of Pichincha, Ecuador, and report a new locality for the recently described N. worleyae. We include a detailed description of the osteology of both species and discuss their phylogenetic relationships. The new species is differentiated from other species of Noblella by having discs of fingers rounded, without papillae; distal phalanges only slightly T-shaped; toes slightly expanded and rounded distally, without papillae; dorsum uniform brown with irregular suprainguinal dark brown marks; venter yellowish cream, ventral surfaces of legs and thighs reddish to brownish cream; and dark brown throat. The new locality for N. worleyae is located in Los Cedros Reserve, an area highly threatened by mining. We highlight the importance of protecting endemic species of small vertebrates in northwestern Ecuador.
