Swimming crabs (Crustacea, Decapoda, Portunidae) from One Tree Island, Capricorn Group, Queensland
Abstract
Two species of portunid swimming crab, Charybdis (Goniosupradens) obtusifrons Leene and Thalamitoides quadridens A. Milne Edwards, are recorded from Australia for the first time and a species of Portunus considered to belong to P. longispinosus (Dana) is recorded from Australia for the second time; the status of Australian specimens of this species is discussed. The ecological distribution on One Tree Island of these three species and eight other portunids collected in 1966 and 1967 by Australian Museum expeditions is briefly discussed.
