Four new species of California Legless Lizards (Anniella)

A previous genetic study of the California legless lizard (Anniella pulchra) revealed five deep genetic lineages and alluded to morphological differences among them. Here we show that three of these genetic lineages can be readily diagnosed from topotypic A. pulchra through a combination of coloration, scalation, and skeletal characters (trunk vertebra number). A fourth lineage is cryptic, but can be diagnosed from A. pulchra by its karyotype. Leer más.
