Rhizopa gracilipes Stimpson, 1858 #

Rhizopa gracilipes Stimpson, 1858b: 41 ; Alcock 1900b: 322; Rathbun 1931: 100 [list]; Shen 1940a: 230; Wong et al. 2021: 37, fig. 58, pl. 11F.

Type: Neotype ò in now NHMD (designated by Ng 1987).

Type locality: Sound of Koh Chang, Gulf of Thailand (neotype).

Remarks: Based on material obtained from trawling surveys since 2007, this species has been collected often and is not particularly rare. We believe it is likely to have been recorded under other names (possibly “ Typhlocarcinus species ”) in older local literature as they are very similar externally. The G1 of this species, however, is very distinct as it has the tip truncated ( Ng 1987).
