Remarks. Pleonexes qeshmensis was originally described as Ampithoe qeshmensis by Layeghi & Momtazi (2018). However, based on the following characters, Ampithoe qeshmensis is transferred to the genus Pleonexes ; reduced and round spur on peduncle of male uropod 1, expanded basis of pereopods 3 and 4, and prehensile pereopods 5–7.

Pleonexes qeshmensis is distinguished from Pleonexes nargessi sp. nov. by the following character states (character states of P. nargessi in parentheses): palm of male gnathopod 2 with robust seta (without seta), first uropod with naked outer ramus (8 setae on outer ramus), first male gnathopod without defining angle (with a defining angle), the length ratio of flagellum to peduncle on the second male antenna is 1/2 (1/5), and prehensile P5-7 (simple).
