REMARKS

Well-sculpted carapaces similar to that of the extant and iconic Heikeopsis japonica (Figs 1; 19 A-D) have been recorded from the Holocene of the Umeda Formation, Osaka City (Kaneko 1958), of the ‘Reclaimed Sand’ around the Nagoya Port, Aichi Prefecture (Morita 1977) or Nanyo Formation, Aichi Prefecture (Umemoto & Karasawa 1998). It is a pity that none of the pereiopods 2 or 3 of these crabs have been preserved to check if they are long and thin as in the typical H. japonica in the living fauna.
