Taiwan: South China Sea , collected by Taiwan University, 1400 m: 2 ovigerous female (21.6 x 26.4 mm, 19.0 x 21.6 mm) ( ZRC 2008.0991 ) .— Tungsha Is., South China Sea , coll. P.-H.

Remarks. The specimens from the Pacific coast of the Philippines examined here are larger than those reported from the South China Sea and the Wallis and Futuna Islands (described as Hypsophrys futuna Guinot & Richer de Forges, 1995 ) ( Chen 1986; Ng & Chen 1999). The anterolateral spine is stronger in the Philippines material and the black spot on the male chela is relatively larger. These differences can probably be attributed to the larger sizes of the specimens. Individuals are usually bright red in colour when alive ( Fig. 18A–F) but sometimes deep orange ( Fig. 18G).
