Another step through the crux: a new microendemic rock-dwelling Paroedura (Squamata, Gekkonidae) from south-central Madagascar

Using an integrative taxonomic approach including genetic and morphological data, we formally describe a new microendemic gecko species belonging to the Paroedura bastardi clade, previously referred to as P. bastardi D. We name this taxon currently known from Anja Reserve and Tsaranoro Valley Forest (south-central Madagascar), as P. manongavato sp. nov. The new species differs from other species of the P. bastardi clade by >= 12.4% uncorrected p-distance at the mitochondrial 16S rRNA gene and it forms a monophyletic group in the COI mtDNA phylogenetic tree. It lacks haplotype sharing at the nuclear KIAA1239 and CMOS genes with the other species of the same complex, including the syntopic P. rennerae. Given its limited extent of occurrence and high levels of habitat fragmentation linked to forest clearances and fires, we propose the IUCN Red List Category of Critically Endangered, based on the B1ab(iii) criterion. The conservation value of Anja Reserve and Tsaranoro Valley Forest is remarkable. Preserving the remaining deciduous forest habitat is of paramount importance to protect these narrow-range reptile species.

Automated summary

Using an integrative taxonomic approach, a new microendemic gecko species, P. manongavato sp. nov., is formally described. It differs from other species in the P. bastardi clade genetically and morphologically. Due to its restricted range and habitat fragmentation, it is proposed to be classified as Critically Endangered.
