Two new lepidapedine lepocreadiids, Austroholorchis procerus sp. n.
and Lepidapedella sillaginodesi gen. n., sp. n., are described from
the teleost Sillaginodes punctata taken near Kangaroo Island, South
Australia.
Austroholorchis procerus is distinguished from
its congeners by its elongate shape, the extent of the vitelline fields,
the confluence of vitelline fields between the testes and the length of
the hindbody.
Lepidapedella sillaginodes is distinguished from most lepidapedine
genera by the delimited external seminal vesicle (also
interpretable as the proximal part of a bipartite cirrus-sac). The new
genus is distinguishable from its closest relative, Lepidapedon, 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 parasites in
sillaginid fishes are discussed.
