|Types||Holotype: CNAR (= UNAM = MZFC) 02778|
|Diagnosis||Diagnosis. This species has (1) supra- auricular scales protuberant and knoblike, with no indication of spines; (2) supranasals not expanded and not in contact at dorsal midline; (3) frontonasal present and usually not in contact with frontal; (4) posterior internasals almost twice as long as anterior internasals(1.6-2.0); (5) no canthals; (6) three anterior temporals; (7) parietal not in contact with median supraoculars;(8) a single occipital; (9) posterior head scales strongly convex and knoblike; (10) anterior supercilliarynot in contact with cantholoreal; (11) posterior suboccular in broad contact with lower primary temporal; (12) preauricular scales notoriously enlarged and in one row; (13) postmentals usually two (only 1 out of 14 had one); (14) posterior infralabials usually elongated; (15) six longitudinal nuchal scales; (16) dorsal scales in 23-27 transverse rows;(17) dorsal scales in 10-12 longitudinal scale rows; (18) ventral scales in 12-14 longitudinal scale rows;and (19) 5-6 brown dorsal markings in adults (Fig. 4). Abronia martindelcampoi differs from A. deppii in having (1) well developed enlarged knob-like posterior head scales (Fig. 2); (2) lower anterior temporal fused with penultimate supralabial;(3) no azygous scale between interparietal and interoccipital; (4) preauricular scales notoriously enlarged; (5) head width in adult males >22 mm and > 18 mm in females; (6) ratio of head width to head length >0.75 in adult males; (7) number of scale whorls on unregenerated tail77-86 (x= 80.7); (8) number of infralabial scales 8-10 (only one had seven); (9) number of longitudinal dorsal scale rows 10-12; (10) dorsal ground color grayish to pale olive green in life (grayish in preservative)with dark brown markings which, if confluent on the vertebral region, may be asymmetrical;(11) dorsum of head pale brown to olive green, usually unblotched, individual scales with fine dark vermiculations, some specimens with large dark area on top of head, more, rarely a few, black individual scales (including both upper anterior temporals); (12) ventral region immaculate cream colored in adults, rarely with faint suggestion of yellowish orange (see below); and (13) upper lips mostly unmarked. It differs from other species of the subgenus Abronia (sensu Campbell and Frost, 1993) in having oblique longitudinal rows of dorsal scales, where fuscolabialis, taeniata, and graminea have parallel longitudinal scale rows and taeniata and graminea do not; in most specimens, one lower temporal contacts the postoccular series and a single occipital, where mixteca and oaxacae have three occipitals and two primary temporals contacting postocular series; has body coloration that is not uniformly green like graminea; has six nuchals,where graminea has four (only juveniles of graminea have bands on the dorsum of the body).|
