| Reproduction | oviparous |
| Types | Holotype: SMF 89688, adult male; collected by Sebastian Lotzkat and Andreas Hertz on 23 April 2009. |
| Diagnosis | Diagnosis: A medium-sized species (SVL in largest specimen examined 78.0 mm in males, 76.7 mm in females) of the genus Anolis (sensu Poe, 2004) that differs from all Central American anoles except A. beckeri, A. cristifer, A. fungosus, A. pentaprion, A. salvini, A. utilensis by (1) having (1) extremely short hind legs (fourth toe of adpressed hindlimb usually reaching to level of tympanum; ratio shank length / head length 0.49–0.84); (2) smooth, juxtaposed ventral scales; (3) a relatively short tail (ratio tail length / SVL 1.0–1.5). Anolis charlesmyersi differs from A. beckeri by having a pronounced serrated caudal crest (versus lacking a pronounced serrated caudal crest). Anolis charlesmyersi differs from A. cristifer by having a double row of slightly enlarged middorsal scales, not forming a serrated crest (versus a serrated middorsal crest, at least on posterior portion of dorsum, present in A. cristifer). Anolis charlesmyersi differs from A. fungosus by lacking bony parietal protuberances (versus having a pair of small bony parietal protuberances posterior and lateral to interparietal plate). Anolis charlesmyersi differs from A. pentaprion by having a brick red (in life) dewlap with few large widely spaced gorgetal scales scattered across the dewlap or in loosely arranged rows with 4–9 widely spaced scales (versus a pink dewlap with purple pigment between rows of gorgetal scales and with regular rows of 17–25 small narrowly spaced gorgetal scales). Anolis charlesmyersi differs from A. salvini by having smooth, obliquely conical ventral scales (versus keeled), lacking a dark interorbital bar (versus present), and lacking enlarged postcloacal scales (versus males with a pair of greatly enlarged postcloacal scales). Anolis charlesmyersi differs from A. utilensis by having the proximal subdigital scales of toes differentiated as slightly broadened lamellae (versus those scales granular) and by having a pronounced serrated caudal crest (versus lacking a pronounced serrated caudal crest). |

| Etymology | The specific name is a patronym for Charles W. Myers in recognition of his important contributions to the herpetology of Lower Central America in general and to the understanding of the taxonomy and sytematics of the anoles of the pentaprion group in particular. |
