|Types||Holotype: FMNH 100109 (was EHT-HMS 1506)|
|Diagnosis||DIAGNOSIS. Resembling Anolis gadovii Boulenger, in most characters, differingin possessing widely separated, narrow and ill-defined frontal ridges; nares vertically compressed; supraorbital semicircles broadly in contact, separated from the supraocularsby a single series of scales; a large, single series of scales between the occipital plate and the supraorbital semicircles; dewlap reddish. [for further details SMITH refers to SMITH 1933: 315 where he called this species A. gadovii].|
Diagnosis. A moderate-sized to moderately large species (SVL in largest male 58.5 mm, largest female 51.0 mm) of the genus Anolis (sensu Poe 2004) that differs from all other Mexican and Central American congeners except A. gadovii, A. liogaster, A. omiltemanus, A. peucephilus, and A. taylori 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 dunni 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) and by having a pinkish to orange red male dewlap with semicircular pale streaks and blotches (vs. uniform purple to pink in A. liogaster, and uniform orange yellow in A. omiltemanus and A. peucephilus). Also, A. dunni has longer hind legs than A. omiltemanus and A. peucephilus with the longest toe of adpressed hind leg usually reaching to a point between ear and eye or to posterior border of eye, rarely to ear opening or to mideye (vs. to level of ear opening or to a point between shoulder and ear opening 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). Anolis dunni differs from A. gadovii by having shorter hind legs with the longest toe of adpressed hind leg usually reaching to a point between ear and eye or to posterior border of eye, rarely to ear opening or to mideye (vs. to level of mideye or anterior border of eye in A. gadovii), absence of a bold reticulated body pattern (vs. such a pattern present in A. gadovii), and a pinkish to orange red male dewlap with semicircular pale streaks and blotches (vs. pink to purple in A. gadovii). Anolis dunni differs from A. taylori by the lack of a bold color pattern consisting of contrasting white longitudinal body stripes in large males (vs. such a contrasting pattern usually present in adult males in A. taylori) and by having a red or orange red male dewlap with yellow or whitish markings (vs. red with bold bluish purple semicircular markings in adult males in A. taylori). (KÖHLER et al. 2014).
