The deep-sea lobster family, Polychelidae Wood-Mason, 1875, contains six genera and 38 species worldwide, of which nine species in three genera have been reported from Taiwan. Herein we present four new records of Polychelidae from Taiwan, namely Pentacheles validus A. Milne-Edwards, 1880, Stereomastis surda (Galil, 2000), Willemoesia forceps A. Milne-Edwards, 1880, and W leptodactyla (Thomson, 1873). A total of 13 species in four genera of Polychelidae are now known from Taiwan; a key to the species is provided.
