TL;DR: Graphical visualization and statistical analyses showed that, like body coloration, the green and the brown morph are more distinctive from each other than either is from the blue morph, although the differences in display units among the color forms are subtle.
Abstract: Headbob displays from 22 adult male Anolis conspersus of three "color morphs" (green, brown, and blue) were videotaped in the laboratory. Frame-by-frame coordinates of the vertical head mo- tions were used to generate display-action-pattern (DAP) graphs. Field observations had revealed that only one type of headbob display ("Type A") was performed when males displayed to nonspecific audiences while moving around their territories ("male-alone context"). During staged male encounters in the lab ("male-male context"), Type A displays and a second type of display ("Type B") were produced. The two types of displays were partitioned into units that were compared among the color morphs. We then trans- formed the display units with principle components analysis and used one-way ANOVAs to test statistically for differences among the color morphs at the "unit" level. Finally, we used discriminant function analysis to test for color morph differences at the "display" level. Graphical visualization and statistical analyses showed that, like body coloration, the green and the brown morph are more distinctive from each other than either is from the blue morph, although the differences in display units among the color forms are subtle. Given that A. conspersus is a member of the seven-species Anolis radiation on Jamaica, we compare the structure of one of its displays (Type A) with that of its closest relative, Anolis grahami. Last, we speculate on the possible origin of the unusual display structure observed in the A. conspersus Type B display.

TL;DR: Study of the male caudal structures and of the egg demonstrate that these names represent a single species of Anolis lizards.
Abstract: Parathelandros anolis Chitwood, 1934, Pharyngodon anolis (Chitwood, 1934) sensu Acholonu (1976), and Spauligodon caymanensis Bursey and Goldberg, 1995 have been reexamined from Anolis lizards (Polychrotidae) of the Caribbean. Study of the male caudal structures and of the egg demonstrate that these names represent a single species. The specimens are assigned to Spauligodon anolis (Chitwood, 1934) n. comb. Spauligodon caymanensis is considered a junior subjective synonym of S. anolis.

TL;DR: Examination of aspects of ecological and morphological variation among and within A. conspersus populations throughout Grand Cayman found the blue and green morphs were difficult to categorize, suggesting the A.conspersus color system is more complicated than previously believed.
Abstract: Understanding color polymorphism and associated ecological and morphological divergence is important to improving out knowledge of diversity and speciation; anoles are a model clade for addressing these questions. Anolis conspersus (the Grand Cayman blue-throated anole) is endemic to a small island and has color variants (green, blue, and brown morphs) that are spatially arranged despite a lack of wider environmental gradients. I examined aspects of ecological and morphological variation among and within A. conspersus populations throughout Grand Cayman to evaluate potential divergence between color morphs. No substantial differences in habitat use or morphology were detected. The blue and green morphs were difficult to categorize, suggesting the A. conspersus color system is more complicated than previously believed.
