Completing a taxonomic puzzle: integrative review of geckos of the Paroedura bastardi species complex (Squamata, Gekkonidae)

The Paroedura bastardi clade, a subgroup of the Madagascan gecko genus , currently comprises four nominal species: P. supposedly widely distributed in southern and western Madagascar, ibityensis montane endemic, tanjaka neglecta both restricted to central west region island. Previous work has shown that is species complex with several strongly divergent mitochondrial lineages. Based on one two nuclear markers, plus detailed morphological data, we undertake an integrative revision this complex. Using representative sampling for seven five genes furthermore propose phylogenetic hypothesis relationships among clade. Our analyses reveal at least three distinct independent evolutionary lineages referred . Conclusive evidence status these comes from multiple cases syntopic occurrence without genetic admixture or intermediates, suggesting reproductive isolation. We discuss relevance line conditions under which concordant differentiation unlinked loci sympatry provides powerful approach delimitation, taxonomically implement our findings by (1) designating lectotype now extreme South-East (2) resurrecting binomen guibeae Dixon & Kroll, 1974, applied predominantly South-West, (3) describing third species, rennerae sp. nov., northernmost distribution within
