A new species of Bryophryne (Anura: Strabomantidae) from the Cordillera de Vilcabamba, southeastern Peruvian Andes

Abstract

A new species of Bryophryne (Anura: Strabomantidae) from the Cordillera de Vilcabamba, southeastern Peruvian Andes. We describe a new species of Bryophryne from the Cordillera de Vilcabamba in Department Cusco, in the southeastern Peruvian Andes. The new species differs from all other congeneric taxa, except and by the presence of vocal sac and vocal slits in males, and by producing advertisement calls. The new species is distinguished from and by skin texture, presence of small, oblique dentigerous processes on the vomer, ventral coloration ranging from bluish-gray to whitish-gray with irregular or reticulate dark brown spots, and call composed of two or three notes. The new species is further characterized by having dorsal skin shagreen with tubercles, discontinuous dorsolateral folds, skin smooth on ventral transition from montane forest to high Andean puna, where it occurs in moist microhabitats under moss and rocks at elevations from 3519 to 3707 m a.s.l. vocales, y por emitir llamados nupciales; además, se diferencia de y por la textura de su piel, la presencia de procesos vomerianos pequeños y oblicuos, coloración ventral gris azulada a gris clara con manchas marrones irregulares o reticuladas, y llamado nupcial compuesto por dos o tres notas. Los especímenes de la nueva especie se caracterizan además por tener piel ventrales, y presencia de quillas laterales en los dedos de manos y pies. Esta especie habita los bosques altoandinos, entre la puna y el bosque montano, y fue encontrada en ambientes húmedos entre musgo y bajo piedras a elevaciones de 3519 a 3707 m s.n.m.

A New Genus of Terrestrial-Breeding Frogs (Holoadeninae, Strabomantidae, Terrarana) from Southern Peru

“…Furthermore, males of all three species of Qosqophryne are known to emit advertisement calls (unknown in all species of Bryophryne, except possibly for B. bustamantei). We have described the advertisement calls of Q. gymnotis and Q. mancoinca [14,17]. One of us (LM) has recorded the advertisement call of a male Q. flammiventris (MUBI 13365) at the type locality, and this call is composed of 3-4 short notes (~15-35 ms duration) at dominant frequency ~3000 Hz.…”

“…We used the literature (i.e., original species descriptions) for species whose specimens we could not examine. We have described the advertisement calls of B. gymnotis and B. mancoinca [14,17], and have heard and provided a short description of the call of B. flammiventris [15]. We refer readers to the original publications for details on recording methods.…”

“…Since Hedges et al [1] published their molecular phylogeny, researchers have continued discovering terrestrial-breeding frogs: the number of species of Bryophryne has increased from two to 14 species [12][13][14][15][16][17], and the number of species across all Holoadeninae genera from 36 to 151 species [8]. As far as we know, all species of Bryophryne have micro-endemic distribution, and are only known to occur at their respective type localities and immediate surroundings [2,12,[14][15][16]18].…”
