Distinguished by the ventral margin of epimeral plate that forms an acute angle with the body axis anteriorly on pleonite I, and a much shorter PVII than PVI. [Zeidler, 2003] P. gracilis is readily distinguished by the presence of numerous spines on the anterior margins of pereopods 5 to 7, by the distinctly shorter pereopod 7 compared to pereopod 6, and by the shape of the pleonites, particularly pleonite 1 the anterior margin.

According to<br /> Brusca (1981), the spination of pereopods 5 to 7 and<br /> the shape of pleonite 1 are particularly reliable<br /> characters.</td></tr></tbody></table>
