Paulin, C. D., 1986. A new genus and species of morid fish from shallow coastal waters of
southern Australia. Mem. Mus. Vict. 47: 2(11-206.
Eeyorius hutchinsi . a new monotypic genus and species is described from specimens col-
lected in shallow coastal waters of Tasmania, Victoria and Western Australia. Affinities lie
with Pseudophycis and Lotella but Eeyorius differs from those genera in dentition and otolith
The family Moridae is represented in
shallow coastal waters of Australia by
Pseudophycis Gtinther and Lotella Kaup
(Paulin, 1983). Both genera arc readily distin-
guished on the basis of otolith shape (Karrcr,
1971; Fitch and Barker. 1972) and dentition.
Otoliths of Pseudophycis can be distinguished
from those of Lotella by the expanded rather
than smooth dorsal margin; a crista superior as
long as crista inferior rather than two-thirds
length; ostium equal to rather than shorter
than cauda; and a flat rather than recessed col-
Pseudophycis has a band of brush-like teeth
whereas Lotella has an outer row of large
widely spaced teeth and an inner band of
smaller teeth (Kaup, 1858; Gunther, 1862;
Specimens of Moridae with otoliths charac-
teristic of Lotella but with a band of brush-like
teeth were reported from Victoria, Australia,
by Paulin (1983). These, and a number of addi-
tional specimens are here described as a new
genus and species.
Methods of taking counts and measurements
follow Paulin (1983). Counts of first dorsal fin
rays include the minute rudimentary first ray.
Osteological observations were made on a
specimen cleared and stained by the trypsin-
alizarin technique, and supplemented by
radiographs of other specimens.
Specimens examined are deposited in the
following institutions: Australian Museum,
Sydney (AM); Western Australian Museum,
Perth (WAM); Museum of Victoria, Mel-
bourne (NMV); National Museum of New
Zealand, Wellington (NMNZ).
Eeyorius gen. nov.
L^p//a.-Paulin, 1983: 82 (not Lotella Kaup).
Material examined. Pseudophycis baehus. 6 specimens + 4
pairs otoliths, NMNZ P. 7730; P. barbatus 10 specimens +
2 pairs otoliths, NMNZ P. 6783, P. 7707; P. breviuscula 8
specimens + 1 pair otoliths, NMNZ P. 14301; Lotella
rhacinus 12 specimens + 6 pairs otoliths, NMNZ P. 4098,
4640; AM 115330-15: L. phveis 6 specimens + 1 pair
otoliths, AM 120270-008, WAM P. 26004-011.
Diagnosis. Snout obtusely rounded, not pro-
jecting beyond mouth. Maxillary extending to
beneath rear margin of orbit. Barbel present.
Teeth small, pointed, arranged in 5-6 irregular
rows forming a brush-like band on jaws. Upper
jaw with a graded series, the outer teeth only
slightly larger. Lower jaw with teeth of equal
size. No teeth on vomer or palantines.
Otolith pointed at both ends, ostium com-
prises 40.6% of otolith length and is shorter
than cauda; Crista superior almost as long as
crista inferior (Fig. 1).
Type species. Eeyorius hutchinsi sp. nov.
