idae). Mem. Mus. Vict. 48: 85-87.
Aplodactyius westralis sp. nov., from south-western Australia, is described. It is separable from
other species of Aplodactyius by the following combination of characters: lanceolate teeth, dis-
tinctly convex interorbital space, obtuse head profile, and recticulate pattern of pale markings
on the body and fins.
The family Aplodactylidae presently contains
four species belonging to two nominal genera:
Crinodus lophodon (Giinther) from New South
Wales; Aplodactyius araidens Richardson from
New Zealand, Victoria, South Australia and Tas-
mania; A. etheridgii (Ogilby) from north-eastern
New Zealand, Kermadec Islands, Lord Howe Is-
land, Norfolk Island, New South Wales and Vic-
toria; and A. punctatus (Valenciennes) from Chile
and Peru. An additional species, Aplodactyius
westralis sp. nov., collected from south-western
Australia is described herein.
In the following description, morphological
values for the holotype are presented first and
ranges for the paratypes follow in parentheses.
Type specimens are deposited in the Australian
Museum, Sydney (AMS) and the Western Aus-
tralian Museum, Perth (WAM).
