A new species of the genus Pinctada, Pinctada phuketensis sp. nov., is described from samples collected in Thailand. It is distinguished from other species by morphological and molecular data. Phylogenetic analysis supports its status as a distinct species closely related to Pinctada albina and Pinctada nigra.
A new species of the genus Pinctada is described from samples collected from the east coast of Phuket Island, Thailand in the Andaman Sea. Pinctada phuketensis sp. nov. is distinguished from other species on both molecular and morphological data. Morphologically, the valves of P. phuketensis are characterized by a slightly developed to undeveloped posterior auricle, a small, narrow slit-like byssal notch, the absence of hinge teeth, and a pale to transparent non-nacreous border, with a few dark brown or red blotches. This new species resembles P. fucata but differs by its smaller size and the absence of hinge teeth. Phylogenetic analyses based on both mitochondrial (COI) and nuclear (18S rDNA, ITS1 and ITS2) genes and spe-cies delimitation using COI data strongly support that P. phuketensis is a distinct species, which is closely related to Pinctada albina and Pinctada nigra.
