We describe a new species of anole of the genus Norops from near Quebrada Grande, Departamento de Copan, in western Honduras. It is distinguished from all other Mexican and Central American species of the genus by having an ocellated shoulder spot. A suite of other characters is also provided that will distinguish the new species from all other species of Norops of northern Central America.

We describe a new species of anole of the Norops schiedei group from western Guatemala. A distinctive suite of characters distinguish it from the remaining species of the group (e.g., prenasal scales fused to circumnasal; most midventral scales weakly keeled; all scales in prefrontal depression strongly keeled; scales comprising supraorbital semicircles about same size as scales between semicircles; all keels on dorsal surface of head oriented nearly longitudinally; hemipenis large and bilobate).

We describe Anolis benedikti sp. nov. from lower montane elevations of the Cordillera de Talamanca in Bocas del Toro and Chiriqu\&$\#$39;{\i} provinces of western Panama, and adjacent Puntarenas province of eastern Costa Rica. The new species is very similar to A. magnaphallus, A. pachypus, A. pseudopachypus, and A. tropidolepis, which inhabit the same mountain range. It differs from these species in the coloration of the male dewlap, which is red with a yellow anterior margin (versus male dewlap solid purplish red in A. magnaphallus and A. tropidolepis, red with a central yellow blotch in A. pachypus, and solid yellow in A. pseudopachypus), and in pholidotic characters.

Based on differences in hemipenial morphology we recognize two species of anoles related to Anolis polylepis: Anolis polylepis (Pacific versant of central and southern Costa Rica and western Panama, excluding the Osa Peninsula) and a species described herein which is restricted to the Osa Peninsula. The two species differ in hemipenial morphology (hemipenis bilobed in A. polylepis versus unilobed in the species from the Osa Peninsula) but show no discernable differences in external morphology (i.e., morphometrics, scalation, coloration, male dewlap). We therefore consider them to be cryptic species. At the neck of the Osa Peninsula where the ranges of the two species meet we detected a narrow (about 1 km wide) hybridization zone in which only individuals with an intermediate hemipenial morphology occur.

Based on differences in coloration, morphometrics, and scalation, I recognize seven species of anoles related to Anolis pentaprion in Central America: Anolis beckeri (southeastern Mexico to northern Nicaragua), A. cristifer (Pacific lowlands of Chiapas to central Guatemala), A. fungosus (Caribbean premontane zone from central Costa Rica to western Panama), A. pentaprion (Caribbean lowlands of southern Nicaragua to northwestern Colombia, also on Pacific versant in central and eastern Panama), A. salvini (Pacific premontane and lower montane zones from central Costa Rica to western Panama), A. utilensis (restricted to Isla de Utila, Honduras), and a new species (from the Pacific lowlands of Costa Rica and western Panama) described herein. The new species differs from A. pentaprion by having a red male dewlap with few large, widely spaced gorgetal scales scattered across the dewlap (pink with purple pigment between rows of gorgetals, and with regular rows of numerous small, narrowly spaced gorgetal scales in A. pentaprion). Furthermore, I resurrect the name A. beckeri Boulenger for the pentaprion-like populations of anoles distributed from southeastern Mexico to northern Nicaragua. Anolis beckeri differs from A. pentaprion most obviously in the dorsal tail scalation (a serrated caudal crest present in A. pentaprion versus no such crest in A. beckeri) and dewlap scalation (gorgetal rows with 17\–25 narrowly spaced scales in A. pentaprion versus gorgetal rows with 4\–10 widely spaced scales in A. beckeri). Finally, SMF 83608 is proposed as the neotype for Anolis pentaprion. I provide standardized descriptions of A. beckeri, A. pentaprion, and the new species described herein.
