Material examined

Conic Island Cave , 22 ° 219540 N 114 ° 239220E, Hong Kong; 1 ♀ (6.6×5.0 mm) ( ZRC 2003.0344 View Materials ), coll. 25 October 2002   ; 1 young ♀ (4.5× 3.5 mm) ( NHM 2003.700), coll. 21 October 2002   .


This is a species typically associated with epifauna and sponges, often in areas with faster flowing waters (see Goh et al. 1990). The rounded carapace with the low and serrated anterolateral lobes, as well as the simple gonopod1 with a straight distal part, and truncate tip are diagnostic characters ( Takeda and Miyake 1969). Its presence in Hong Kong is recorded for the first time. This species may need assigning to its own genus.
