Abstract

One diphyllidean and five tetraphyllidean cestodes from Australian elasmobranchs are described and figured.Echinobothrium heroniensissp.nov., fromHimantura granulata(Macleay, 1883) possesses two groups each of 42 apical hooks, eight rows each of 25 hooks on the cephalic peduncle and ten testes in each proglottid. InAnthobothrium sexorchidumsp.nov. fromT. lymna(Forskal, 1775) there are only six testes and the bothridium is irregularly divided into a number of shallow areolae while inRhinebothrium himanturisp.nov. fromHimantura granulatathere are 22 proglottids, 52 loculi and 19–20 testes. Comments are made on the taxonomy ofRhinebothriumsp.,Spiniloculus mavensisandYorkeria parva.The value of some helminths, especially cestodes from elasmobranchs, as an aid to the study of the taxonomy, biology and zoogeography of their hosts is briefly discussed with reference to some previous papers on this topic. Previous work on the cestodes of Australasian marine fishes is summarized briefly.
