|Diagnosis||Diagnosis: “A species of Abronia having: (1) distinctive spinelike supra-auricular scales in subadults and adults; (2) unexpanded supranasals; (3) a median frontonasal scale, not contacting frontal; (4) posterior internasals not greatly enlarged; (5) discrete canthals; (6) usually four primary temporals, usually the lower two (rarely three) contacting the postoculars; (7) no parietalmedian supraocular contact; (8) a single occipital; (9) posterolateral head scales not knoblike; (10) anterior superciliary contacting cantholoreal or not; (11) the posterior subocular broadly separated from the lower primary temporal by the penultimate or antepenultimate supralabial, the posteriormost scale in this series to reach the orbit; (12) preauricular scales relatively small, usually disposed in two rows, usually imbricate or subimbricate; (13) postmental divided or single; (14) posterior infralabial not elongate; (15) six longitudinal nuchal scale rows; (16) 27-30 dorsal transverse scale rows; (17) 14 dorsal longitudinal scale rows arranged parallel to ventrolateral fold; (18) 12 ventral longitudinal scale rows; (19) adult dorsal coloration greenish (fig. 11E); (20) juvenile pattern with a broad pale brown middorsal stripe. This species differs from all other species of Abronia having spinelike supra-auricular scales, except for A. ochoterenai, A. matudai (variably), A. leurolepis, and A. fimbriata, in having 12 longitudinal ventral scale rows, and having the lateralmost rows wider than adjacent ventral rows. Abronia smithi differs from A. fimbriata and A. leurolepis in having a frontonasal scale, from A. leurolepis in having imbricate or subimbricate preauricular scales rather than multiple rows of protuberant scales, relatively short posteriormost infralabial, and definite keels on the body scales; from A. fimbriata in having unexpanded supranasals and discrete canthals; and from A. matudai in having four primary temporals (usually two, rarely three or four in A. matudai), no parietalmedian supraocular contact, and in lacking expanded supranasals. Abronia smithi appears to be most similar morphologically to A. ochoterenai, but differs from that species in having usually four or five, rather than three, primary temporals, usually having a fourth temporal scale row in evidence (clearly absent in A. ochoterenai), having the subocular separated from the lower primary temporal (broadly in contact in A. ochoterenai), usually having a divided rather than single postmental, having two or fewer rows of imbricate to subimbricate preauriculars rather than three rows of nonimbricate preauriculars, and in that adult females are yellow-green with darker spotting, rather than with dark transverse bands, and in having the circumorbital region bright yellow in A. smithi, not the ambient head color as in A. ochoterenai.” Campbell & Frost 1993: 30.|
