Two new species of lepidapedines (Digenea, Lepocreadiidae) from the King George whiting Sillaginodes punctata (Perciformes, Sillaginidae) from off Kangaroo Island, South Australia

Two new lepidapedine lepocreadiids, Austraholorchis procerus sp. n. and Lep idapedella sillaginodesi gen. n., sp. n., are described from the teleost Si llaginodes punctata taken near Kangaroo Island, South Australia. Austraholo rchis procerus is distinguished from its congeners by its elongate shape, t he extent of the vitelline fields, the confluence of vitelline fields betwe en the testes and the length of the hindbody. Lepidapedella sillaginodes is distinguished from mast lepidapedine genera by the delimited external semi nal vesicle (also interpretable as the proximal part of a bipartite cirrus- sac). The new genus is distinguishable from its closest relative, Lepidaped on, by the narrow internal male duct, the position of the ovary adjacent to the ventral sucker, by muscular features associated with the metraterm and the distribution of the uterus. Some general features of digenean parasite s in sillaginid fishes are discussed.
