摘要

Leontopithecus is the largest genus of Callithrichidae, occupying isolated remnants of the Atlantic Forest in Brazil. The objective of this study was to investigate the ultrastructure of the dorsum of the tongue of golden-headed lion tamarins. Tongues of ten adult lion tamarins kept in captivity at the Center of Primatology of Rio de Janeiro (CPRJ-FEEMA) were analyzed under scanning electron microscopy. The three vallate papillae were distributed in a V shape, and each papilla was surrounded by a deep sulcus and an external pad; the medial papilla showed a round shape and the lateral one was elliptical. The filiform papillae were shaped as a crown or as finger-like papillae, and were distributed throughout the tongue, including the margins, except for the posterior region. The fungiform papillae were scattered among the filiform papillae, in a disperse manner, from the apex to the lateral vallate papillae. The foliate papillae had a typical ultrastructure, with folds that ranged in number from 1 to 3. With respect to vallate papillae, we identified the microridge and pore pattern on its surface. Further studies are required to confirm the hypotheses on the ultrastructural aspects described for golden-headed lion tamarins.
