Original description: “Head once and two-thirds as long as broad, slightly longer than the tibia; forehead concave ; frontal ridges distinct, divergent; upper head-scales rugose, not keeled; scales on frontal ridges and supraorbital semicircles large, the latter in contact on the interorbital region ; three large supraoculars, forming together a disk separated from the supraorbital semicircle by two series of small scales; occipital large, a little larger than the ear-opening, separated from the supraoi'bital semicircles by two series of small scales ; canthal scales four, loreal rows six; six or seven upper labials to beloAv centre of eye; ear-opening large, vertically oval. Gular appendage very large, extending far back on the breast; gular scales smooth. Body compressed; no dorso-nuchal fold. Dorsal scales small, smooth or faintly keeled, irregular, juxtaposed; lateral scales minute, granular; ventral scales larger than dorsals, smooth, juxtaposed. The adpressed hind limb reaches the eye ; tibia as long as the distance between the end of the snout and the ear; digits moderately dilated ; 20 lamellfe under phalanges II and III of the fourth toe. Tail feebly compressed, not crested, once and three-fourths length of head and body. No enlarged postanal scales. Greyish above, with black Avavy and vermicular lines ; two parallel black lines on each side from shoulder to hip ; belly white ; gular appendage bright red. Total length 225 millim. Fore limb 37 millim. Head 20 mm, Hind limb 63 mm, Width of head 12 mm, Tail 145 mm, Body 60 mm.

Diagnosis. A moderate-sized to moderately large species (SVL in largest male 76.0 mm, largest female 63.0 mm) of the genus Anolis (sensu Poe 2004) that differs from all other Mexican and Central American congeners except A. dunni, A. liogaster, A. omiltemanus, and A. peucephilus by having (1) smooth ventral scales; (2) an oval patch of usually three greatly enlarged supraorbital scales; (3) a pair of greatly enlarged postcloacal scales in males. Anolis gadovii is unique among the Mexican and Central American anole species in exhibiting a bold pattern of dark brown blotches and lines on the head and body. Anolis gadovii differs from A. liogaster, A. omiltemanus, and A. peucephilus by having the middorsal scales not or only 2-4 rows slightly enlarged (vs. 10–15 rows of dorsal scales moderately enlarged in A. liogaster, A. omiltemanus, and A. peucephilus). Also, A. gadovii has longer hind legs than A. omiltemanus and A. peucephilus with the longest toe of adpressed hind leg reaching to level of mideye or anterior border of eye (vs. to level of ear opening or to a point between shoulder and ear opening in A. omiltemanus and A. peucephilus), and a pink to purple male dewlap (vs. uniform orange yellow in A. omiltemanus and A. peucephilus), and usually only a single pair of greatly enlarged sublabial scales in contact with infralabial scales (vs. usually two pairs in A. omiltemanus and A. peucephilus). Aside from its bold reticulated pattern, A. gadovii differs from A. dunni by longer hind legs with the longest toe of adpressed hind leg reaching to level of mideye or anterior border of eye (vs. to a point between ear and eye or to posterior border of eye, rarely to ear opening or to mideye in A. dunni) and a pink to purple male dewlap (vs. pinkish to orange red with semicircular pale streaks and blotches in A. dunni). (KÖHLER et al. 2014).
