Notes on the postcranial osteology of the sand lizard Liolaemus azarai (Squamata: Liolaemidae)
Full text linkWe examined skeletons of seven adult and juvenile specimens of Liolaemus azarai that were cleared and double-stained. The states of twenty three postcranial skeleton characters were described and compared with others Liolaemus species. Our findings complement the current knowledge about the osteological variation in Liolaemus and the character states may include in a data matrix to future phylogenetic studies.Fil: Gonzalez Marin, Maria Andrea.

Cranial osteology of Liolaemus azarae Avila 2003 (Squamata: Liolaemidae): contributions to the morphological variation of the genus
Full text linkCon el objetivo de aportar información sobre la variación de los caracteres osteológicos en el género Liolaemus, examinamos siete individuos de Liolaemus azarae tratados con la técnica de diafanización y tinción diferencial de cartílago y hueso. Describimos el estado de quince caracteres craneales y comparamos ocho elementos óseos con dos especies del grupo wiegmanni: L. occipitalis y L. lutzae. Liolaemus azarae se distingue de estas últimas por siete caracteres.In order to complement the current knowledge about the osteological characters variation in Liolaemus genus, we analyzed seven cleared and doublestaining cranial skeletons of Liolaemus azarae. Fifteen characters states were described and compared eight bone elements with L. occipitalis and L. lutzae, both species belonging to the wiegmanni group, L. azarae is distinguished by seven characters.Fil: Gonzalez Marin, Maria Andrea.
