Morphological diversity and genetic structure within Lerista kalumburu Storr, 1976 (Squamata: Scincomorpha: Sphenomorphidae)—taxonomic implications

摘要

Discovery of a population of two-toed Lerista allied to L. kalumburu prompted a morphological and genetic examination of this taxon. Molecular analysis showed limited divergence and paraphyly of three-toed populations with respect to the two-toed form. We contend that these populations are best viewed as a single species exhibiting remarkable diversity in limb morphology. As this prevents successfully identifying the taxon using published keys, we provide a new diagnosis and a redescription of the species.
