DiagnosisDiagnosis: A small species (our Species D of the A. nebuloides complex, see above; SVL in largest male 50.0 mm, largest female 50.5 mm) of the genus Anolis (sensu Poe 2004) that differs from all Mexican and Central American anoles except A. nebuloides, A. nietoi, A. megapholidotus and a species we are describing below (our Species E of the A. nebuloides complex) by having a combination of (1) strongly keeled ventral scales; (2) usually a patch of three greatly enlarged supraocular scales; (3) 10–12 rows of greatly enlarged dorsal scales that are larger than ventral scales; (4) short hind legs, longest toe of adpressed hind leg usually reaching to posterior margin of eye, occasionally to a point between levels of ear opening and eye or to mideye (to ear opening in single female), ratio shank length/SVL 0.90–1.07; (5) circumnasal usually in contact with first supralabial; and (6) a large pink dewlap in males and a very small pink dewlap in females (Fig. 26). In external morphology, A. stevepoei is most similar to A. nebuloides, A. nietoi, A. megapholidotus and a species we are describing below (our Species E of the A. nebuloides complex). Anolis stevepoei differs from A. nebuloides, A. nietoi, and A. megapholidotus by having (1) a rather gradual transition over 3 to 4 scales between the enlarged dorsal scales and the lateral body scales (vs. a more abrupt transition over only 1 or 2 scales); (2) the edges of the field of enlarged dorsal scale rows forming an undulating line due to single enlarged scales or groups thereof outside the main field (vs. the edges of this field well defined and in a more or less straight line) (3) and by having a pink to purple male dewlap (vs. more reddish). Anolis stevepoei differs from Species E in hemipenial morphology (lobes rudimentary with a single apical field void of ornamentation, and with a flap-like structure at tip of apex in A. stevepoei vs. lobes well developed with two apical fields void of ornamentation—one on each lobe, and without a flap-like structure at tip of apex in Species E) and in the average values of several morphometric and pholidotic characters, most obvious in (1) number of midventral scales in one head length; (2) dorsal scales between levels of axilla and groin; and (3) subdigital lamellae on Phalanges II–IV of Toe IV (see Table 8 in Köhler et al. 2014). 
Comment 
EtymologyThe name stevepoei is a patronym honoring Steven Poe who has contributed substantially to our knowledge of the phylogeny and taxonomy of anoles.
