Cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004–2005 and AURORA 2007 expeditions

The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004–2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus minax sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus bruceiTavares, 1991, and Xeinostoma sakaiiTavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweaeTavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp. nov., is also reported, and is most similar to C. curvirostrisSakai, 1965, from Japan.
