DistributionMexico (E Oaxaca), elevation 1500-1600 m

Type locality: Cerro Baul, Oaxaca, Mexico; cloud forest at an elevation of about 1600 m.  
TypesHolotype: UTA R-6641, an adult male, University of Texas at Arlington Collection of Vertebrates. Original number JAC 3103, collected 25 July 1977 by Julio Ornelas Martinez. 
DiagnosisDiagnosis: The species with which A. ornelasi may be most easily confused is A. reidi (character states in parentheses) from the Sierra de las Tuxtlas in southern Veracruz, but it differs from the latter species by having a frontonasal that contacts the frontal (prefrontals in contact medially), four anterior temporals (rather than three), a parietal that does not contact the median supraoculars (upper primary temporal not in contact with frontoparietal), and fewer transverse rows of dorsal scales (30-33 versus 34-36). The salient features that distinguish species of Abronia inhabiting the southeastern Oaxacan highlands and the Sierra de los Tuxtlas are presented in Table 1 (Campbell 1984). 
CommentDistribution: The type locality is in the vicinity of Colonia Rodulfo Figueroa, in the Atlantic drainage of the Rio Mono Blanco, 19 km NW Rizo de Oro, Chiapas.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyNamed after Julio Ornelas Martinez, a friend and companion of J. Campbell.
