Two genera of deep water brachyuran crabs, Platypilumnus (Goneplacidae) and Trachycarcinus (Atelecylidae) are recorded from Taiwan for the first time. Platypilumnus soelae Garth, 1987, is previously known only from northern Australia and southern Indonesia. Trachycarcinus elegans Guinot et Sakai, 1970, was previously regarded as a Japanese endemic.
