B. Parasit, hung., 21: 31-52. 1988. ABSTRACT. Four species of Anoplocephaloides Baer, 192 3 were found In Microtus_spp. in Bulgaria: A. dentata (Galli-Valerio, 1905) from M.jiiyalis, M. suj^erraneus and jyT^u^nJhej-i: A. rauschi Genov, Georgiev et Biserkov, 1984 from J^_nj_Yjilis and J^^ubjterrjine_us_L A. tenoramuraiae sp. n. from M. nivalis and RL^ubJ:erraneus; and Anoplocephaloides (? ) sp. from JVLjiiyalis. The species are described and figured. A. tenoramuraiae sp. n. is differentiated from A.blanchardi sensu Baer, 1923, sensu Dollfus, 1961, sensu Tenora et al., 1985, Paranoplocephala omphalodes sensu Spassky, 19 51, A. variabilis (Douthitt, 1915), A_. cf. variabilis sensu Rausch, 1976. The taxonomic structure of the genus is analysed and 8 groups of species thought to be different phyletic lines are proposed. KEY WORDS: Anoplocephaloides dentata, Anoplocephaloides rauschi, Anoplocephaloides tenoramuraiae sp. n. , Anoplocephaloides (? ) sp. , Microtus spp., Bulgaria, taxonomic structure of Anoplocephaloides. The genus Anoplocephaloides Baer, 1923 emend. Rausch, 1976 includes 28 species: 23 species in rodents, 4- in lagomorphs and 1- in perissodactyls (SPASSKY, 1951; RAUSCH, 1976; KAMIYA et al., 1979; MURAI et al., 1980; TENORA et al., 1982, 1984, 1985; GENOV et al., 1984). The fundamental similarity of these cestodes lies in the pattern of uterus development. The genus can be accepted only temporarily in its recent composition because there are obviously some distinct phyletic lines in it (RAUSCH, 1976, TENORA and STANEK, 1985). The erection of the different phyletic groups is complicated because of the lack of sufficient and correct descriptions for a number of species. Hence reinvestigations with modern methodical aproaches of Anoplocephaloide

s spp. are necessary. This paper includes the results of morphological investigations on Anoplocephaloides spp. parasitizing Bulgarian rodents and an attempt to analyse the taxonomic structure of the genus.
