Poore, G.C.B. and Lew Ton, H.M., 1988. More Australian species of Haliophasma (Crustacea:
lsopoda: Anthuridae). Memoirs of the Museum of Victoria 49: 85-106.
Six new species of Haliophasma Haswell (H. beaufortia and H. dillwynia from north-western
Australia; H. darwinia from north Queensland; H. swainsonia and H. templetonia from south-
eastern Australia; and H. blandfordia from all these areas) are described and figured. New dis-
tributional records of eight other south-eastern Australian species are added. A key to all known
species of Haliophasma from Australia is presented and the generic composition discussed.
This paper follows an earlier contribution on spe-
cies of Haliophasma from south-eastern Australia
(Poore, 1975). It is based on additional material
from the same region and from tropical Austra-
lia. Material upon which the work is based has
come from the collections of Australian museums
and the Commonwealth Scientific and Industrial
Research Organization (CS1RO), Division of Fish-
eries North-west Shelf Survey.
Material is lodged in the Museum of Victoria,
Melbourne (NMV), Australian Museum, Sydney
(AM), Queensland Museum, Brisbane (QM), Tas-
manian Museum, Hobart (TM), South Australian
Museum, Adelaide (SAM) and Western Australian
Museum, Perth (WAM). Poore and Lew Ton
(1986) explained the abbreviations used in figures.
Species names are derived from the Australian flora
and follow a pattern established by Poore (1984)
for Paranthura. Scale marks are 1.0 mm and refer
to the whole animal only.

Type species. Haliophasma purpureum Haswell,
Remarks. Poore's (1975) generic diagnosis is gener-
ally adequate and requires only a few additions.
The flagellum of antenna 2 is of 3 articles (the
small basal article was overlooked by Poore). The
mandibles are asymmetrical, the left molar having
a small tooth which is absent in the right molar (see
fig. 1). Pereopod 1 article 6 has a submarginal row
of setae along the palm and also a mesial row. On
pereopods 2 and 3 article 6 is barely more swollen
than on succeeding legs and bears a stout seta on
its posterodistal margin. Pereopods 4-7 have a stout
seta on the posterodistal margins of articles 5 and 6.
Negoescu and Wagele (1984: 135) referred to
Haliophasma as a "collecting pot". To some extent
this is true and attempts to divide it into smaller
genera have not been successful. Poore (1975)
recognised three groups of species from south-
eastern Australia separated on the basis of the ros-
trum, pereopod 1, mandible, maxilliped and shape
of head. Attempts to place species from other
regions in these groups have not been successful.
Exclusion of//, geminatum on the basis of absence
of dorsal grooves and pits is not warranted and
Silophasma Schultz is thereby synonymised.
Negoescu and Wagele (1984) regarded both Ex-
anthura Barnard and Nemanthura Wagele as valid
genera. Exanthura was differentiated from
Haliophasma on the basis of two
