|Distribution||Mexico (Campeche, Chiapas, Quintana Roo, Tabasco, Veracruz, Oaxaca), Belize, Guatemala, Honduras, N Nicaragua|
Type locality: “Yucatán”
|Types||Holotype: IRSNB 2010|
|Diagnosis||Diagnosis. A medium-sized species (SVL in largest specimen examined 60.6 mm in males, 55.4 mm in females) of the genus Anolis (sensu Poe, 2004) that differs from all Central American anoles except A. charlesmyersi, A. cristifer, A. fungosus, A. pentaprion, A. salvini, and A. utilensis by 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 beckeri differs from A. charlesmyersi by having a pink dewlap in life with purple pigment between rows of gorgetal scales and regular rows of numerous small narrowly spaced gorgetal scales (versus a brick red dewlap with few large widely spaced gorgetal scales scattered across the dewlap). Anolis beckeri 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 beckeri 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 beckeri differs from A. pentaprion by lacking a pronounced serrated caudal crest (versus having a pronounced serrated caudal crest) and by having gorgetal rows with 4–10 widely spaced scales (versus gorgetal rows with 17–25 narrowly spaced scales). Anolis beckeri 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 beckeri differs from A. utilensis by having the proximal subdigital scales of toes differentiated as slightly broadened lamellae (versus those scales granular).|
|Comment||Species group: Norops auratus Species Group (fide Nicholson et al. 2012).Belongs to the pentaprion group which includes seven species: fungosus, ibague, ortonii, pentaprion, sulcifrons, utilensis, and vociferans. Norops pentaprion cristifer is listed here as valid species.|
Synonymy: McCranie (2009), Townsend and Wilson (2010a), and Wilson and Johnson (2010) implicitly regarded this name as a synonym of Norops pentaprion, but Köhler (2010) resurrected it as a distinct species. Poe considers the diagnostic characters suggested by Köhler as insufficient to distinguish between A. beckeri and utilensis (Poe 2016).
Distribution: not in Yucatan state (Mexico) according to GONZÁLEZ-SÁNCHEZ et al. 2017.
|Etymology||The name beckeri is a patronym honoring the Belgian arachnolo- gist Leo ́ n Becker.|
