Abstract
<jats:p>
Seven species of ampithoid amphipods are reported from subtidal macroalgae
living in Port Jackson, Sydney, Australia. In the genus
Ampithoe the Indo–West Pacific species
Ampithoe kava Myers, 1985, is recorded for the first
time from Australia, and two new species, A. caddi, sp.
nov. and A. ngana, sp. nov., are described. One new
species ofCymadusa,C. munnu, sp.
nov., is described. The genera Exampithoe
(Melanesius), Peramphithoe and
Plumithoe are recorded for the first time from
Australian waters. The new species E.
(M.) kutti, sp. nov. and
Peramphithoe parmerong, sp. nov. are described, and
Plumithoe quadrimana (Haswell,
1879b), comb. nov. is redescribed and a neotype is
selected. New ecological and behavioural information is presented for these
species. A new key and diagnoses for all known genera of Ampithoidae are
presented. Paradusa Ruffo, 1969 is synonomised with
Cymadusa Savigny, 1816.Exampithoe
(Melanesius) gracilipes Ledoyer,
1984 is transferred to Exampithoe
(Exampithoe) and Cymadusa uncinata
Stout, 1912 and C. variata Sheard, 1936 are transferred
to Paragrubia.</jats:p>
