lateral uterine branches on each side. Eggs 0.020—0.021 x 0.013—0.014 mm, oncosphere 0.019—0.020x0.012—0.013 mm. Hooks of oncosphere 0.003 mm long. Apical end of eggs distinctly convex. Host: Cricetulus barabensis PALLAS. 1773. Location : small intestine. Locality: Mongolia, Barun Urt 112° 37' East, 47° 18' North, 1240 m above sea level, 8—9. 8. 1972. leg. F. MÉSZÁROS. TWO type specimens deposited in the Zoological Department of the Hungarian Natural History Museum, Budapest, Holotype coll. No.: M 19/1— 1972; paratype coll. No.: M 14/1—1972. Differential diagnosis: The new species is closely related to Eurasian and North-American species of the genus Catenotaenia JANICKI, 1904, parasitizing rodents. They are characterized by a smaller number of uterine branches: 7—30x2. C. asiatica sp. n. closely resembles in its morphology and anatomy the species Catenotaenia cricetorum KIRSHENBLATT, 1949, principally differing from it in the following characters: 1. number of uterine branches: 19—24x2 (C.c): 18— —22 (C. a. ); 2. number of testes: 90—147 (C.c): 60—80 (Ca.); 3. shape of eggs: aj)ical part of eggs not convex (C.c): apical part of eggs distinctly convex (Ca.). As far as the other species of Catenotaenia are concerned, C. asiatica sp. n. differs by the following features: from C pusilla (GOEZE, 1782), and C. matovi, GENOV, 1971, in the higher number of uterine branches and lower number of testes; Figs. 1—3. Catenotaenia asiatica sip. n.: 1 = hermaphrodite proglottis, 2 = mature proglottis, 3 : egg.
