SynonymEnyalioides rubrigularis TORRES-CARVAJAL, DE QUEIROZ & ETHERIDGE 2009
Enyalioides rubrigularis — TORRES-CARVAJAL et al. 2011 
DistributionEcuador (Zamora Chinchipe)

Type locality: finca de Mesías San Martín (3°51'23"S, 78°51'53"W, 1154m elevation), near Piuntza, Provincia Zamora Chinchipe, Ecuador  
TypesHolotype: QCAZ 8483 (Fig. 1), an adult male, collected on 23 June 2008 by O. Torres-Carvajal, E. Arbeláez, A. Carvajal-Campos, and D. Salazar. 
DiagnosisDiagnosis. The new species differs from all other species of Enyalioides, except for E. praestabilis, in having distinct caudal whorls, smooth or feebly keeled ventrals, fewer than 32 longitudinal rows of dorsals in a transverse line between dorsolateral crests at midbody, and in lacking projecting dorsal and limb scales. Males of the new species can be distinguished from E. praestabilis by having larger scales on the ventral surface of the thighs (Fig. 2 in TORRES-CARVAJAL et al. 2009), and by having gulars with black margins (Fig. 3). Th e skin between gulars is black in some male specimens of E. praestabilis, but gulars lack black margins. In addition, gular scales in males of the new species vary between bright orange and red, and there is no black mark on the gular region posteromedially; males of E. praestabilis have cream or yellow gular scales, and some specimens have a black patch covering the gular fold and posteromedial portion of the gular region (Fig. 3). Th e new species usually has two femoral pores, whereas E. praestabilis has normally one femoral pore; otherwise, both species are very similar in scale counts and morphometric characters (Table 1).
CommentZookey ID: 
EtymologyThe name rubrigularis is an adjective in the nominative singular and derives from the Latin words ruber (=red) and gula (=throat). It refers to the characteristic orange or reddish throat and chin of adult males, which distinguishes the new species from other species of Enyalioides.
