Resumo
Tamandua Gray, 1825 contains two species of anteaters: Tamandua mexicana (Saussure, 1860), which occurs in southern Mexico, throughout Central America and south to the west of the Andes in South America, and Tamandua tetradactyla (Linnaeus, 1758), widely distributed in South America, from Venezuela to northern Argentina, as well as Trinidad and Tobago. Historically, different coloration patterns have been attributed to the coat of Tamandua, with T. mexicana typically showing a partial or complete dark "vest" on the dorsal portion of the body, whereas T. tetradactyla can show a complete, partial, or absent vest and a coat varying from golden, pale yellow and pale gray to brown or black. These different coat colors are sometimes treated as inherent characteristics of subspecies of Tamandua. Here, we review color variation in Tamandua and describe six chromatic disorders for the genus: albinism, leucism, "brown" variation, melanism (partial and total), xanthochromism (partial and total) and, for the first time for anteaters, erythrism. In addition, we detail the morphological expression and geographic distribution of these anomalies in populations of Tamandua from Central and South America.(AU)
