between the genera Paranthias and Cephalopholis. They al- 

 so cited several morphological and ontogenetic similarities 

 between the two genera. In the present study, an analysis 

 of 16 allozyme loci produced a Nei's (1978) unbiased genetic 

 distance of 0.356 between P. furcifer and C. fulva, which is 

 within the range reported between Ocyurus chrysurus and 

 species ofLutjanus (Chow and Walsh, 1992). The mitochon- 

 drial DNA sequence divergence data indicated that P. fur- 

 cifer is closer to, or at least no farther from, C. fulva (0.036) 

 than is C. cruentata (0.042) and that the congeners are most 

 distant, (0.052). Both values are within the range reported 

 between other congeneric serranids (Graves et al., 1990). 



Taxonomic revision of P. furcifer is not recommended at 

 this time; however, the incidence of hybridization and the 

 small genetic distance between C. fulva and P. furcifer sug- 

 gest that a full-scale phylogenetic analysis of the subfam- 

 ily is warranted. Such a study would have to include more 

 species of Cephalopholis, other members of the subfamily 

 Epinephelinae, and P. colonus, the eastern Pacific gemi- 

 nate species of P furcifer.
