Paratypes. CORBIDI 07210 and 07213, an adult female and a juvenile, respectively, collected with the holo- type by P. J. Venegas, V. Duran, C. Z. Landauro, and L. Lujan. CORBIDI 07212, an adult male from the same loca- tion of the holotype but taken on 19.VIII.2010 by P. J. Venegas.
|Diagnosis||Diagnosis. Enyalioides rudolfarndti can be easily distinguished from other species of Enyalioides from the Amazon basin by the combination of the following characters: (1) scales posterior to the superciliaries enlarged (relative to adjacent scales), forming a well defined longitudinal row of distinctly raised scales across the lateral edge of the head in juveniles and adults of both sexes; (2) 30 or fewer longitudinal rows of dorsals in a transverse line between the dorsolateral crests at midbody; (3) a distinct orange round blotch on the antehumeral region in adult males; (4) ventral scales strongly keeled; (5) caudal scales heterogeneous in size on each autotomic segment. The orange round blotch on the antehumeral region in adult males of Enyalioides rudolfarndti is present also in some male individuals of E. palpebralis (Fig. 4). Furthermore, the new species also shares with E. palpebralis the presence of enlarged scales posterior to the superciliaries and the presence of strongly keeled ventral scales; how- ever, the latter species can be easily distinguished from E. rudolfarndti by having a superciliary triangular flap that projects posterolaterally over each eye. In addition, E. palpebralis is the only species that has (most specimens) a discontinuous vertebral crest, having a small gap on the neck, and lacks femoral pores (Torres-Carvajal et al. 2011). Enyalioides cofanorum and E. microlepis share with the new species the presence of strongly keeled ventral scales and caudal scales of heterogeneous size on each autotomic segment. However, E. cofanorum differs from E. rudol- farndti (characters in parentheses) by having with more than 33 dorsal scales in a transverse line between the dor- solateral crests at midbody (30 or fewer) and scattered, projecting, large dorsal scales (absent). Enyalioides microlepis differs from E. rudolfarndti by having more than 40 dorsal scales in a transverse line between the dorso- lateral crest at midbody (30 or fewer dorsal scales), and a low vertebral crest (high). In addition, adult males of E. cofanorum and E. microlepis have a black patch that covering the gular region (absent).|
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||The specific name is a patronym for Dr. Rudolf G. Arndt of Pomona, New Jersey, USA, in recognition of his financial support for the improvement of the herpetological collection of CORBIDI through the BIOPAT-Programme.|
