7. T etratirotaenla polyacantha (Leuckart, 1856) Abuladze, 1964 Name of larva: Armatetra th yridium polyacantha (Leuckart, 1856), Intermediate hosts: Ondatra zibethicus , Clethrionomys glareolus , Microtus arvalis. - Localization: body cavity (c. abdominalis). - Extensity: 0.33% in O. zibethicus, 0.36% in C. glare olus and 0.07% M. arvalis. - Intensity: 1-20 specimens. Collection data of the infested intermediate hosts: Ondatra zibethicus - County Győr-Sopron: Kapuvár 20/10/65 (leg. O. SEY) = 1 case. Clethrionomys glareolus - County Borsod-Abaúj-Zemplén: Lillafüred 04/06/30 (leg.I.VÁSÁRHELYI) (1); County Zala: Zajk 29/04/67 (1) = 2 cases. Microtus arvalis - County Vas: Bozsok 17/10/74 (1), 07/01/75 (1) = 2 cases. Characterization of the larval Tetratirotaenia polyacantha Armatetrathyridium polyacantha larvae are situated freely in the peritoneal, rarely in the thoracic cavity, and are oval, sometimes drop-shaped or elongated (Fig. 4). Length of the body is 4 to 12 mm, width varies between 2.5 and 4 mm. The non-encysted larva is actually built up in a similar way to the Cysticercus of Taenia species. The larval bladder has a wall wrinkled to various extents, with an infolding at the anterior portion, and a scolex similar to that of adult worm is found in the anterior third of the larva. Diameter of scolex 0.75 mm, that of rostellum 0.50 mm, those of suckers 0.25 mm. The rostellum contains 55 to 66 characteristically shaped hooks arranged in two rows (Fig. 23). Smaller hooks vary in length from 0.120 to 0.143, the larger from 0.178 to 0.221 mm. The larval form of T. polyacantha was rare in the examined material. Intermediate hosts were found only in member of the Microtidae family. Adult specimens have been collected from the definitive host, Vulpes vulpes (Linnaeus, 1758) (MURAI & TENORA, 1973). According to literature data the range of intermediate hosts is larger (ABULADZE mentions members of the families Muridae and Cricetidae). Note . ABULADZE (1964) erected a new genus to accomodate the species T. polyacantha, based especially on the larval form and named it "armatetrathyridium". This larval form shows great resemblance to the larval form of Taenia martis (both being situated freely in the body cavity). The number of hooks in T. polyacantha (55-66 in contrast with 28-42 of the other species) is not a generic character, since e.g. T. tenuicollis possesses over 50 hooks. The shape of the smaller hooks is different from those of the other taeniid species (Fig. 22), since they have very small handles. VERSTER (1969) rejects the validity of the genus Tetratirotaenla Abuladze, 1964, whereas others have repeatedly used this name (TENORA, WIGER, SHARPILO, etc). It must also be noted that if the validity of the genus Tetratirotaenia was proved, than the species Taenia mar tis (Zeder, 1803) should also be referred here. 8. Cladotaenia globifera (Batsch, 1786) Cohn, 1901 Name of larva: Cladothyridium globifera (Batsch, 1786) Abuladze, 1964. Intermediate hosts: Clethrionomys glareolus . Apodemus flavicollis, Apodemus mic r ops , Apo demus agrárius. - Localization: surface of liver, usually at the edges. - Extensity: 0.36% in C. glareolus, 0.98% in A. flavicollis, 1.54% in A . microps, 0.5% in A. agrárius. - Intensity: 50~"to 500 host-cysts. Collection data of the infested intermediate hosts: Clethrionomy s g lareolus - County Győr-Sopron: Sopron 28/08/70 (1); County Zala: Zajk 29/04/67 (1) = 2 cases. Apodemus flavicoll is - County Hajdú-Bihar: Hajdúbagos 29/09/66 (1); County Pest: Bernecebaráti, Deszkáspuszta 01/04/67 (1), Gödöllő, Babatpuszta 28/10/78 (3), 18/01/79 (2), 14/04/79 (1);' County Somogy: Somogyszob, Baláta-tó 03/08/70 (3); County Vas: Alsóújlak 06/10/77 (1), Oriszentpéter 20/06/67 (1), Vát 04/10/77 (1); County Veszprém: Németbánya 13/08/73 (1), 23/10/79 (1) = 16 cases. Apodemus microps - County Pest: Gödöllő, Babatpuszta 28/10/78 (2), 18/01/79 (1), 21/05/80 (1) = 4 cases. Apodemus agrárius - County Somogy: Somogycsicsó, Ágneslak 11/11/75 = 1 case.
