Abstract Specimens of blue moki
Latridopsis ciliaris
(Forster in Bloch & Schneider, 1801) from New Zealand were shown to differ
from specimens of copper moki
Latridopsis forsteri (Castelnau, 1872)
using two genetic methods--allozymes and muscle proteins. Allozyme techniques
revealed fixed differences between blue and copper moki at 4 out of 15 loci.
There was a genetic distance of 0.31-0.34 between population samples of the two
colour morphs. The two morphs were also distinguished by iso-electric focusing
of muscle proteins. Meristic characters, counted in the specimens studied with
genetic markers, revealed diagnostic markers in tubed lateral line scales and
scales in the lower transverse series. It is concluded that specimens of blue
moki from New Zealand and copper moki from New Zealand and Tasmania are valid
species.
