N2 - A new species of the synallactid sea cucumber genus Pseudostichopus is described, P. aemulatus sp. nov.,
based on genetic (DNA sequences of the mitochondrial gene Cytochrome Oxidase I [COI] gene) and
morphological characters. A comparative molecular study with two other species of the same genus
(P. villosus and P. mollis) and from a di¡erent family (Isostichopus fuscus) was carried out in order to clarify
its taxonomic identity. The nucleotide distance between P. aemulatus sp. nov. and P. villosus and P. mollis is
su⁄cient to support distinct species status. The estimated di¡erence in the number of amino acids, coded
for by a partially sequenced COI gene, within the species of the family Synallactidae ranged from 4 to 18.
The phylogenetic analysis clearly supports separate species status of these sympatric morphotypes, as
indicated by the morphological analysis.
