|Abstract:||The Indo-Pacific labrid fish genus Pseudojuloides Fowler is
characterized chiefly by a slender body (depth usually 4-5 in standard length) ,
IX,1l or 12 dorsal rays, a single pair of canine teeth anteriorly in jaws
followed by incisiform teeth, and a small truncate or near-truncate caudal fin.
Eight species are recognized: P. cerasinus (Snyder), ranging widely from East
Africa to eastern Polynesia; P. argyreogaster (Gunther) from the western
Indian Ocean; the related P. elongatus Ayling and Russell, which exhibits an
anti tropical distribution in the western Pacific (Japan, Australia, and New
Zealand); and the five new species P. atavai from southeast Oceania, P. pyrius
from the Marquesas Islands, P. mesostigma from the Philippine Islands, and
P. xanthomos and P. erythrops from Mauritius. These fishes are small (only
two species are known to exceed 100 mm standard length) , bottom-dwelling
(frequently on rubble or weedy substrata), and most often found at depths of
about 10 to 60 m. All appear to be sexually dichromatic (xanthomos is known
only from a single male specimen); the females of five of the species are
uniform light red and difficult to distinguish from one another.
