Carpoporoides Takeda & Nagai, 1986: 547 , Fig.1 .

Type species. – Carpoporus orientalis Sakai, 1935 , by original designation.

Remarks. – Sakai (1935) described Carpoporus orientalis from Japan, making it at that time, only the second species of the genus to be described and the first to be discovered in the Indo-Pacific. The genus Carpoporus Stimpson, 1871 , was originally established for one western Atlantic species, C. papulosus Stimpson, 1871 . Zarenkov (1971) described a third species, C. guinotae , from the Red Sea and the western Indian Ocean. Serène (1984), citing comments made by Guinot-Dumortier (1960: 161) that there are many carapace, third maxilliped and chela characters distinguishing the Japanese species from the Atlantic one, established the genus Hepatoporus to accommodate both C. orientalis Sakai, 1935 and C. guinotae Zarenkov, 1971 . Serène (1984) designated C. orientalis Sakai, 1935 as the type species. Takeda & Nagai (1986) independently established a new genus, Carpoporoides , to accomodate C. orientalis and a new Japanese species they described, C. distinctus . Both species are known only from Japan. Takeda (1986) subsequently recognized Hepatoporus Serène, 1984 , as having priority over Carpoporoides Takeda & Nagai, 1986 . Davie & Turner (1994) described a fourth species, H. asper , from Western Australia. Hepatoporus now contains five species, including H. pumex , new species.
