Abstract
Allozyme and meristic data were used to compare relationships
among three species of a circumtropical complex of goatfishes that are very
similiar in color and morphology: Mulloidichthys vanicolensis (Valenciennes) of
the Indo-Pacific, M. dentatus (Gill) of the eastern Pacific, and M. martinicus
(Cuvier) of the western Atlantic. The species are distinguished by several
allozyme differences as well as by gill-raker counts. Allozyme data from several
widely separated populations of M. vanicolensis (including isolated islands with
high endemism in other groups) suggest little genetic divergence, consistent with
high levels of dispersal and gene flow. Morphological data suggest greater
divergence between populations of M. vanicolensis from the western Indian
Ocean and the Pacific Ocean than is apparent from allozyme data.
