A new species of Scinax Wagler (Anura: Hylidae) from Paraná, Southern Brazil

Abstract

In this article, we describe a new species of Scinax from the state of Paraná, southern Brazil, based on the external morphology of adults and their advertisement calls. The new species is diagnosed by the size of its males (SVL 27.8-31.6 mm); the snout subovoid in the dorsal view and slightly acuminate in profile; the vocal sac subgular and ventrally not reaching the pectoral region; and the advertisement call composed of a single pulsed note with 7-13 pulses, and a duration of 0.16-0.25s. This new species occurs in natural highland grassland formations, in the threatened ecosystem of the Atlantic Forest in the state of Paraná, southern Brazil.

A reassessment of the vocalization and distribution of Scinax exiguus (Duellman, 1986) (Anura: Hylidae) in the Amazonian savanna of Roraima, northern Brazil, with the description of its aggressive call

“…The acoustic record for S. exiguus from Cantá extends the distribution approximately 65 km southward from the previous southernmost locality at Boa Vista [2] ( Figure 4). Recently, this species was indirectly reported for three localities in the Brazilian state of Roraima (Boa Vista, and two new records: Pacaraima and Tepequém) in a list of examined specimens in the description of S. rossaferesae [10]. Subsequently, one of the authors of the description of S. rossaferesae formalized those records in Araujo-Vieira [f11] as being the first records of S. exiguus in Brazil.…”

Una nueva rana de huesos verdes del género Scinax (Anura: Hylidae) asociada a los bosques subandinos de la cuenca del río Magdalena, Colombia

“…Las líneas de evidencia que apoyan la delimitación de esta nueva especie, incluyen algunos rasgos morfológicos (en adultos y larvas) y bioacústicos, que a nivel supraespecífico han sido empleadas en aproximaciones previas y recientes del género (Araujo-Vieira et al, 2015Brusquettti et al, 2014;Conte et al, 2016;Faivovich et al, 2005;Juncá et al, 2015;Lourenço et al, 2013Lourenço et al, , 2016Sturaro y Peloso, 2014). Por otra parte, Suárez y Lynch (2011) indican que uno de los rasgos larvales para la distinción de Scinax x-signatus frente a S. ruber es la relación del sitio de inserción (inicio) de la aleta dorsal con el cuerpo, la cual se inicia a la altura del borde posterior de los ojos en Scinax x-signatus, mientras que en S. ruber se inicia en la mitad del cuerpo; este último rasgo es compartido con S. caprarius sp.…”
