Kinorhyncha is a phylum of microscopic marine metazoans living from intertidal to abyssal depths. More than 200 species are known; nevertheless, recent studies have pointed out that most of this group's diversity has not been revealed. A survey of the peculiar Meloria Shoals seabed (Ligurian Sea, Italy) led to the discovery of a new kinorhynch named Antygomonas caeciliae sp. nov. A cytochrome c oxidase subunit I (COI) mtDNA gene is reported for the new species; hence, a morphological and molecular approach is used for the description of this new taxon, and a comparison with related species is proposed, including a key to the species of Antygomonas. Some additional COI sequences are reported for other taxa of the phylum, with the aim of developing molecular tools which will be useful for species identification, particularly when dealing with juvenile stages.
