Ezotinorchestia gen. nov. is established to receive Orchestia solifuga Iwasa, 1939. The new genus is defined by an elongate antenna 1 (reaching the mid-point of peduncular article 5 of antenna 2), a 4-dentate lacinia of the left mandible, a mediodistally lobate article 2 and reduced article 4 of the maxillipedal palp, a deeply subchelate male gnathopod 1, the short palm of female gnathopod 1, cuspidactylate pereopods, well-developed pleopods, and the outer ramus of uropod 1 with robust setae. This genus is distinguished from Kokuborchestia Morino and Miyamoto, 2015 by the sexually dimorphic gnathopod 1 and the lack of dense, plumose setae on the pleopodal peduncles.
