Scarthyla vigilans ( Solano 1971)

Type: MBUCV IV-6163

Type locality: “De la carretera entre Coloncito y El Vigía (a los 20 km), Estado Zulia (sic!= Estado Táchira), Venezuela.”

Distribution: Regions 1, 2, 3, 6. Colombia (Magdalena Basin and Llanos), Venezuela and Trinidad ( Smith et al. 2011). In Venezuela, apparent disjunct distribution in lowlands of Maracaibo Lake Basin, high Llanos, Falcón State (Barrio-Amorós et al. 2006), northern Coastal Range, and Delta of the Orinoco ( Rojas-Runjaic et al. 2008). The type locality was situated in Zulia State by Solano (1971), wrongly corrected to Mérida State by La Marca (1992) and here corrected to Táchira State.

Remarks: Hyla vigilans was regarded as incertae sedis by Faivovich et al. (2005). Based on osteology and external morphology, Barrio-Amorós et al. (2006c) proposed to assign H. vigilans to Scarthyla Duellman and de Sá, 1988 despite differences between the tadpoles of both species. Lynch and Suárez-Mayorga (2011) assigned vigilans to Pseudis , as P. vigilans , but that proposal was never considered ( Frost 2019). Despite the controversial supraspecific position of this species, molecular evidence indicates a close relationship between S. goinorum and S. vigilans (B. Noonan and CBA, unpub.).
