Amphibia, Anura, Hylidae, Sphaenorhynchus prasinus Bokermann, 1973: First record of the genus and species for the State of Alagoas, Brazil

Abstract

The genus Sphaenorhynchus Tschudi, 1838 can be characterized by the following morphological synapomorphies: posterior ramus of pterygoid absent; zygomatic ramus of squamosal absent or reduced to small knob; pars facialis of maxilla and alary process of premaxilla reduced; postorbital process of maxilla reduced, not in contact with quadratojugal; neopalatine reduced to sliver or absent; pars externi plectri entering tympanic ring posteriorly; pars externa plectri round; hyale curved medially; coracoids and clavicles elongate; transverse process of presacral vertebra IV elongate, oriented posteriorly; prepollex ossified, bladelike (Duellman and Wiens 1992).The genus Sphaenorhynchus is composed of fourteen species, three with distribution in the Amazon basin [S. carneus (Cope, 1868); S. dorisae (Goin, 1957); and S. lacteus (Daudin, 1800)], ten in the Brazilian Atlantic Forest [S.

Sphaenorhynchini monophyly has always been supported (Araujo-Vieira et al, 2020;Duellman et al, 2016;Pyron, 2014) and several morphological synapomorphies have been suggested…”

“…Elía, 2013). It is possible to observe some of these barriers in the distribution of Sphaenorhynchini species, such as, for example, the Paraíba do Sul River valley in Rio de Janeiro and Minas Gerais states and the Rio Doce River in Espiríto Santo and Minas Gerais states, which together, is the current limit from the distributions of S. canga (seeAraujo-Vieira et al, 2015), S. prasinus (see daSilva et al, 2013), S. pauloalvini (seeFreitas et al, 2009), and S. mirim (see Caramaschi…”
