Type locality: “in cloud forest at 1219 m (4000 feet) elevation on the south slope of Volcán de Agua, Finca Rosario Vista Hermosa, Department of Escuintla, Guatemala. This site is about 12 km (airline) NNE Escuintla at approximately 14° 25' N, 90° 44' W."

Habitat: cloudforest  
TypesHolotype: UMMZ 129013, University of Michigan Museum of Zoology; Paratypes: AMNH, UTA 
DiagnosisDiagnosis: “A species of Abronia having: (1) distinctive spinelike supra-auricular scales in subadults and adults; (2) unexpanded supranasals; (3) a median frontonasal scale; (4) posterior internasals relatively small, although about twice the length of anterior internasals; (5) discrete canthals; (6) two or three primary temporals, the lower two contacting the postoculars; (7) usually no parietal-median supraocular contact; (8) a single occipital; (9) posterolateral head scales not knoblike; (10) anterior superciliary contacting cantholoreal, similar in length to other scales in series; (11) posterior subocular broadly separated from the lower primary temporal by the penultimate supralabial, which is the posteriormost scale in this series to reach the orbit; (12) at least three rows of granular preauriculars; (13) postmental divided; (14) posterior infralabial elongate, often about twice as long as preceding infralabials; (15) six longitudinal nuchal scale rows; (16) 27-28 dorsal transverse scale rows; (17) 14 dorsal longitudinal scale rows arranged parallel to ventrolateral fold; (18) 14 ventral longitudinal scale rows; (19) adults dark green or dark blue-green (fig. 11C, D); and (20) juvenile pattern unknown. This species differs from all other species of Abronia that have spinelike supra-auricular scales, except A. aurita, A. gaiophantasma, A. lythrochila, and some A. matudai, in having 14 longitudinal ventral scale rows. Abronia anzuetoi differs from all other species of Abronia, except A. aurita, A. graminea, and A. smithi, in having a distinctly yellow circumorbital region. Abronia anzuetoi differs from A. aurita in coloration (dark emerald green or dark blue green versus a paler green with yellow and/or orange markings), in having relatively longer posterior internasals, and possibly in being of a larger body size (maximum known SVL 135 mm versus 125 mm). Abronia anzuetoi differs from A. gaiophantasma in having more numerous postoccipital rows between the occipital and first nuchal row (two or three versus one), expansion of the posterior infralabial, and in a green coloration with yellow eye region (versus a brown dorsum and circumorbital region not yellow), and from A. lythrochila in having a divided postmental (usually single in A. lythrochila), and in a green dorsal coloration with yellow orbit (color variable in A. lythrochila, but often brownish or with numerous black markings, never with yellow orbit).” (Campbell & Frost 1993: 23)
