Abstract
Phylogenetic relationships of 31 pomacanthid species representing all genera were investigated by horizontal starch gel electrophoresis. Nei 's genetic distances (D) were calculated and dendrograms constructed f rom allozyme variation in 23 loci. The average D value was 0.03 betwee n conspecific colour variants, 0.40 between congeneric subgenera, and 1.27 between confamilial genera. From the dendrograms the following we re revealed: (1) the generic status of Apolemichthys arcuatus and Hola canthus venustus, as well as the generic and subgeneric status of Cent ropyge multifasciata were confirmed; (2) the subgeneric status of Xiph ypops was confirmed; (3) Pygoplites diacanthus was found to be closely related to members of the subgenus Pomacanthus; (4) Pomacanthus zonip ectus was found to be biochemically distinct from its con-subgeners; ( 5) the genera Pomacanthus and Holacanthus are more closely related tha n currently thought; (6) the Genicanthus species might warrant a subfa mily of their own.
