Pomacentrus maafu is a new species of damselfish which was described from almost 200 fish from Fiji and Tonga. Closely related to Pomacentrus moluccensis from the West Pacific Ocean, Pomacentrus maafu is almost identical in shape and merisitic counts, but it was differentiated based on DNA analysis and it sports a distinct coloration. Compared to the golden yellow lemon damselfish Pomacentrus moluccensis, P. maafu is mostly brown with a golden yellow head, vent and pectoral fins as well as the caudal fin and peduncle.
Pomacentrus maafu is described by Gerald Allen and Joshua Drew in Aquapress volume 18, number 3.
