Four Species of Polylabroides (Monogenea: Polyophisthocotylea: Microcotylidae) on Australian Bream, Acanthopagrus Spp.

Abstract

Two previously described species, Polylabroides australis (Murray, 1931) and P. multispinosus Roubal, 1981, and two new species, P. quadruspinosus and P, longispinosus, were recovered from four species of bream, Acanthopagrus butcheri (Munro), A. australis (Gunther), A. berda (Forskal), and A. latus (Houttuyn). The new species are described and a key to all known species of the genus is given. Zoogeographical distribution and host specificity of all four species are described.
