Macropotrema pertinax gen. et sp. nov. (Digenea : Paramphistomidae) is described from the caecum of the macropodid marsupial Macropus agilis (Gould, 1842) from northern Australia. The new genus is characterised as follows : ventro-terminal acetabulum bearing many papillae ; oral sucker with constriction and paired diverticula ; oesophagus with muscular bulb ; cirrus sac and genital sucker absent ; testes symmetrical, unlobed, preovarian ; Laurer’s canal opening anterior to excretory pore. The genus is placed in the subfamily Pseudodiscinae Näs- mark, 1937. At the point where the worm attaches to the caecal wall of the host, the entire mucosa is destroyed and there is an inflammatory cell infiltration in the intact mucosa surrounding the attachment site.
Abstract
Le nouveau genre présente les caractères suivants : acetabulum ventro-terminal orné de nombreuses papilles; ventouse orale pourvue d’une constriction et de deux diverticules; œsophage muni d’un bulbe musculaire; poche du cirre et ventouse génitale absentes; testicules symétriques, non lobés, préovariens; ouverture du canal de Laurer en avant du pore excréteur. Le genre est placé dans la sous-famille des Pseudodiscinae Näsmark, 1937.
La muqueuse de la paroi du cæcum de l’hôte est entièrement détruite au point de fixation du ver et autour de ce point s’observe dans la muqueuse intacte une infiltration cellulaire inflammatoire.
