Description of a new genus for Cyrtorhina balabacensis Serène, 1971,with notes on the Cyrtorhininae (Decapoda, Brachyura, Raninidae)

抄録

The raninid genus Cyrtorhina Monod, 1956, is revised and restricted to Cyrtorhina granulosa Monod, 1956, from West Africa. A new genus, Flaberhina, is established for C. balabacensis Serène, 1971 from the Philippines and New Caledonia. Despite their superficial similarities, the two genera can easily be separated by the structures of the carapace, eye, antenna, pterygostome, thoracic sternum, pleon and penis. The taxonomy of the subfamily Cyrtorhininae Guinot & Ng, 2020, which contains both fossil and extant taxa, is also reviewed.
