Abstract: | A species of digenetic trematode, Brachylaime antechini (Family Brachylaimidae), is described from adult worms recovered from the intestine and rectum of two species of marsupial mice, Antechinus stuartii(10 of 56 infected) and Antechinus swainsonii (2 of 5 infected). On experimental evidence unencysted metacercariae from the kidney of a terrestrial gastropod, Strangesta capillacea, are considered to be larval stages of Brachylaime antechini. Miracidia, sporocysts and cercariae have not been recovered, but circumstantial evidence suggests that Strangesta capillacea fulfils the role of first intermediate host. Brachylaime antechini most closely resembles Brachylaime chiapensis, a parasite of deer mice in Mexico. |
