Supple skinks (Reptilia; Lygosoma), named for their attenuate limbs, like many other Indochinese herpetofaunal groups, have experienced particular taxonomic turbidity over the past few decades. With a widespread geographic breadth (spanning most of Africa to continental and insular Asia), the majority of species within this group are exceptionally poorly known. As is the case with so many understudied cryptic species groups, Southeast Asian Lygosomine species-complexes, such as Lygosoma quadrupes, require comprehensive molecular and morphological assessments to resolve the evolutionary relationships of these cluttered taxa. Here, using comparative morphological and novel multilocus phylogenetic data, we apply targeted species delimitation techniques to the Lygosoma quadrupes complex, focusing in particular on species from Myanmar. In so doing, we reveal multiple cryptic lineages and provide insight on the taxonomic status of this group, as well as additionally biogeographic discussion. Our dataset also provides opportunities to examine the evolution of body elongation and limb attenuation, which has happened independently in several Indochinese skink lineages.
