Males' dorsal ground color dark olive green, tinged with russet; head lighter and more reddish olive, sides rosy; back and sides with narrower, more distinct lateral stripes running length of body but fading caudally; flanks dark with obscure light spotting and vermiculation; chin and throat pale flesh-color; mesoptychium black with white blotch or indentation; belly blue-gray; females similar to males except dark pencilings more numerous and distinct; suggestion of pale line anteriorly on each side of body (more distinct in juveniles) (Schwartz & Henderson 1991: 190).|
|Comment||This taxon was formally described the same year that Shaw described it, by Daudin (1802: 122), as Ameiva erythrocephala, and has been credited to Daudin in the literature ever since (e.g., Schwartz and Henderson, 1988: 63). However, as Daudin's volume 3 was published in August 1802, at least seven months after Shaw's work appeared, Daudin's name is a junior synonym of Lacerta|
erythrocephala Shaw, Ameiva erythrocephala (Shaw, 1802) [SMITH & DAVID, from the introduction to the facsimile reprint of SHAW 1802].
