Abstract Variation in mitochondrial DNA sequences and
allozymes in four species of trumpeter (family Latridae) from the New Zealand
EEZ and the newly described species, silver trumpeter, from the central South
Pacific Ocean was used to determine the phylogenetic relationships among
this group of fishes. Sequence data for 424 nucleotides of the cytochrome
b mitochondrial gene were obtained for 31 specimens. Three methods
of phylogenetic analysis, maximum parsimony, minimum evolution, and maximum
likelihood, produced similar topologies for species level relationships:
with two pairs of species: Latris pacifica and L. lineata,
and Latridopsis ciliaris and L. forsteri, plus the more divergent
Mendosoma lineatum. There were fixed differences at 9 of 11 allozyme
loci among the species; genetic distances were 0.212 and 0.213 between L.
pacifica and L. lineata, and between L. ciliaris and L.
forsteri, respectively. Based on both mitochondrial DNA and allozyme
data we suggest that L. pacifica is a sister species to L. lineata.
