CommentSynonymy: after Grummer et al. 2014.

Similar species: S. aurantius is a highly variable species. It was previously confused with S. brownorum but differs from this and all but one species within the S. scalaris group by a lack of blue belly patches in males. It shares with S. chaneyi an absence of blue belly patches, but differs from this species in size, number of dorsal scales, number of scales around midbody, and presence of an un-patterned morph. The new species further differs from S. chaneyi, and all other species in the S. scalaris species group, by unique phylogenetic position revealed through species delimitation based on multi-locus nuclear DNA. Females are difficult to distinguish from other regional species of bunchgrass lizard such as S. brownorum.

Diagnosis. Sceloporus aurantius sp. nov. belongs to the S. scalaris species group, sharing with other species in that group the following characters: parallel lateral scale rows (except in S. goldmani), femoral pore series in contact or separated by no more than two scales, females with smooth preanal scales, and males with lateral abdominal color patches (Smith 1939; Smith et al. 1997; Watkins-Cowell et al. 2006). Sceloporus aurantius sp. nov. differs from all S. scalaris group species except S. chaneyi by the lack of blue belly bars in adult males. Sceloporus aurantius sp. nov. differs from S. chaneyi in adult size (mean snout-to-vent length 49.8 mm vs. 45.7 mm), number of dorsal scales (mean of 39.2 vs. 42.3), number of scales around midbody (mean of 37.9 vs. 40.4), and presence of an un-patterned morph (absent in S. chaneyi). Although not a diagnostic character state, Sceloporus aurantius sp. nov. further differs from S. chaneyi, and all other species in the S. scalaris species group, by unique phylogenetic position revealed through species delimitation (Grummer et al. 2014; Fig. 2). 
EtymologyThe specific epithet is formed by the Latin adjective aurantius, which means “orange colored”, in reference to the orange dorsolateral streak of males.
