Peter K.L. Ng, Chia-Wei Lin, and Ping-Ho Ho (2018) Three species of reef-dwelling pilumnid crabs are recorded for the first time from Taiwan: Heteropilumnus decharmoyi (Bouvier, 1915), Heteropilumnus satriai Yeo, Rahayu and Ng, 2004, and Viaderiana sentus Ng, Dai and Yang, 1997. Heteropilumnus decharmoyi was previously assigned to Pseudolitochira Ward, 1942, but its carapace and epistomal characters indicate that the species should be referred to as Heteropilumnus De Man, 1895, instead. Heteropilumnus satriai and Viaderiana sentus were described from the South China Sea and both are now recorded from Taiwan. Heteropilumnus satriai is redescribed and refigured because the type specimen was a male that had been parasitised by a rhizocephalan and had anomalous features.

Key words: Pilumnidae, Pilumnoidea, Heteropilumnus, Crustacea, Brachyura, Taiwan.
