Abstract

Amphinome rostrata (Pallas, 1976) is a polychaete worm with a seemingly widespread distribution. The first documented instance of this species was recorded in 2024 at the Bahía de Banderas región, located in the central Mexican Pacific. The identification of these specimens was based on the morphology of the caruncle and branchiae. In this study, we employed a molecular approach to validate the taxonomic identification using molecular evidence. Specifically, we conducted an analysis of the mitochondrial gene 16S (RNAr)  from specimens examined in the 2024 study. This analysis confirms the presence of A. rostrata  in the region and their disjunct distribution.  as a potential invasive species with a disjunct distribution that includes recorded locations in the Western and Eastern Pacific, Indian Ocean, Gulf of Mexico, Caribbean Sea, Atlantic coast of South America, and the Iberian Peninsula.
