Diagnosis. Antenna 1 slightly longer than antenna 2 and with uniarticulate accessory flagellum. Ventral margin of coxa of male gnathopod 2 posteriorly produced into a triangular expansion.

Male gnathopod 1 carpochelate and larger than gnathopod 2, carpus with tooth on the distal margin, posterodistal corner and a smaller tooth on the posterior margin.

Remarks. This species has been reported from Thailand, India and Japan ( Wongkamhaeng et al. 2012; Ariyama 2020; Kumar et al. 2024). Ariyama (2020) recorded this species from Okinawa Island and Iriomote Island, Japan and corrected its name from G. halophilus to G. halophila because the gender of the genus is feminine. Recently Kumar et al. (2024) recorded this species from India as Grandidierella halophilus and commented that G. halophila (Ariyama 1920) seemed to be a different species from G. halophilus ( Wongkamhaeng et al. 2012) . Kumar et al. (2024) described the following differences between these two materials: in G. halophilus the male gnathopod coxa 2 is produced into a prominent triangular expansion (versus a not so prominent triangular expansion in G. halophila ); the male gnathopod 1 carpus is elongate (versus carpus more oval in G. halophila ); antenna 1 flagellum is 24- articulate (versus flagellum 14-articulate in G. halophila ). It is possible that all these differences could be due to the variation in the size of the examined specimens. The specimen examined by Wongkamhaeng et al. (2012) is much larger ( 6.9 mm) than the one examined by Ariyama (2020) ( 4 mm).

Distribution. Inner Gulf of Thailand, Samut Sakorn ( Wongkamhaeng et al. 2012); Okinawa Island and Iriomote Island, Japan ( Ariyama 2020) and Haripur, Odisha, India ( Kumar et al. 2024).
