(Cestoda: Anoplocephalidae) a parasite of Microtus cabrerae (Rodentia) in Spain" - Murai, É, - Tenora, F. - Rocamora, J. M. Parasit. Hung. LL 35-37. 1980. ABSTRACT. Paran

oplocephala mascomai sp. n. an anoplocephalid tapeworm parasitizing the endemic Iberian rodent Microtus cabrerae is described. Microtus cabrerae is a vole species endemic to the Iberian Peninsula (ELLERMAN and MORRISON-SCOTT, 1951), and there are no previous data on its helminth parasites. Mr. Ignacio IBANEZ, Centre for Applied Zoology in Madrid, have so far collected 70 specimens of this species for parasitological examination. One anoplocephalid species was recorded for the host. The strinkingly small specimens of this tapeworm were kindly surrendered to us for scientific study, which we gratefully acknowledge. After a detailed study, it turned out to be a new species which we dedicate to Prof. Santiago MAS-COMA (University of Barcelona). Paranoplocephala mascomai sp. n. Material studied: Seven specimens of tapeworms from the host Microtus cabrerae Thomas, 1906. - Localization in the host: first portion of small intestine (duodenum). Localities: Pelayos de la Presa (Madrid), Villanueva de los Escuderos (Cuenca), Spain. Intensity of invasion: 1-8 specimens in one host. - Extensity of invasion: 70 Microtus cabrerae dissected: 9 positive. Description (all measurements in millimetres): small, ribbon-like tapeworms. Length of strobila 14 - 21 (average 15), the maximum width in postmature segments 1.9. Number of segments 90 - 135 (average 110). Segments containing ripe eggs 13 - 17 in number. Length: width ratio in mature segments: 1:5, in gravid segments 1 : 4. Width of scolex 0.30 - 0.43, suckers 0.15-0.18 in diameter. Neck unsegmented, very short: 0.2-0.5. Genital pores unilaterally. Cirrus sac 0. 20 x 0. 07 and 0. 24 x 0. 09 in mature and postmature segments, respectively. Cirrus opinose. Vesicula seminalis interna 0.07 - 0. 09 x 0. 09 - 0. 15. Vesicula seminalis externa in the maximum measures 0.08 x 0.04. Testes about 30 - 34 in number. Testes position: reaching to aporal part of ovary, sometimes also to the middle of vitelline gland; testes reach into aporal part of segments there crossing over ventral excretory canal. Prostatic gland absent. Vagina posteriorly to cirrus sac with a strongly developed musculature. Vagina size: 0. 10 - 0. 13 x 0.03 in both mature and postmature segments. Ovary strongly lobed, 0.25 - 0.37 x 0.10 - 0. 12. Vitelline gland situated at posterior margin of segments, near their middle, size 0.18 - 0.24 x 0.09. Uterus pattern typical for the genus Paranoplocephala Lühe, 1910 emend Rausch, 1976. It always bilaterally crosses the ventral excretory canal. Ventral excretory canal narrow, 0.03 - 0.06 in diameter. Eggs spherical, 0.038 - 0.040 in diameter. Pyriform apparatus well developed. The morphology and anatomy of Paranoplocephala mascomai sp. n. are shown in Figs. 1-5. Holotypus: No. 7802204 (in two slides). Locality: Pelayos de la Presa (Madrid, Spain). Deposited in the Hungarian Natural History Museum, Budapest. Paratypes: No. 7802204 (one slide) and No. 78022102 (one slide), both of the locality of Holotypus; No. 76022501 (three slides), locality: Villanueva de los Escuderos (Cuenca,
