Some members of the Limnoriidae are important marine wood-borers. The taxonomy of
the family was studied with emphasis on species from the Australasian region. The Lim-
noriidae are reduced to two genera: Limnoria Leach and Paralimnoria Menzies. The genus
Phycolimnoria is synonymised with Limnoria.
Species from Australia are redescribed: Limnoria indica Becker and Kampf, L. insulae
Menzies, L. multipunctata Menzies, L. nonsegnis Menzies, L. pfefferi Stebbing, L. plaiy-
cauda Menzies, L. quadripunctata Holthuis, L. rugosissima Menzies, L. sublittorale
Menzies, L. tripunctata Menzies and L. unicornis Menzies.
New species from Australia are: L. agrostisa, L. echidna, L. gibbera, L. glaucinosa, L.
orbellum, L. poorei, L. raruslima, L. torquisa and L. uncapedis. The new species L. loricata
and L. convexa are also described from The Snares, New Zealand.
Species from Papua New Guinea are: Paralimnoria andrewsi (Caiman), P. asterosa Cook-
son and Cragg, L. andamanensis Rao and Ganapati, L. indica, L. insulae, L. kautensis
Cookson and Cragg, L. multipunctata, L. pfefferi, L. tripunctata and L. unicornis.
L. antarctica Pfeffer and L. stephenseni Menzies from Macquarie Island are redes-
Although not found near Australia, L. tuberculata Sowinsky is also redescribed to distin-
guish it from L. tripunctata.
Of the above species, 1 5 are wood-borers, 1 2 algal-borers or dwellers, and 2 seagrass-
borers. Commensal crustaceans found with limnoriids, such as harpacticoid copepods,
ostracods, and amphipods of the family Cheluridae are noted. Tropichelura insulae
(Caiman) (Amphipoda) is recorded from Australia for the first time.
