Abstract The known pempherid fauna of New Zealand comprises
two species:
Pempheris adspersa Griffin, endemic to the
north-eastern shores of North Island; and
P.
analis Waite, found
in the Kermadec Islands as well as Norfolk Island, Lord Howe Island, and the
east and west coasts of Australia.
Pempheris adspersa differs
from
P.
analis in having: some interorbital scales cycloid
(versus all interorbital scales ctenoid), usually 3 or more predorsal scales
cycloid which often form a mesial line of cycloid scales (versus rarely 4 or
fewer predorsal scales cycloid), lateral-line scales 56-68 but rarely more than
66 (versus 63-77, rarely fewer than 65), and scales below lateral line 18-24
but rarely more than 22 (versus 22-27). A principal components analysis
differentiates the two species with only slight overlap. Reports of
P.
compressa from New Zealand are erroneous; descriptions of
P.
compressa and
P.
adspersa have been confused in the
literature.
Pempheris compressa differs from
P.
adspersa in having: anal fin dusky along entire length (versus tips of
first 4-5 anal-fin rays black), gular region scaled (versus unscaled),
segmented anal-fin rays 35-40 (versus 29-35), head depth 36-41% of standard
length (SL) (versus 31-38%), and body depth 44-52% of SL (versus 38-46%). A
principal components analysis clearly differentiates the two species.
