Multivariate analysis of distance measurements of the rostellar hooks András GUBÁNYI Zoological Department, Hungarian Natural History Museum, H-1088, Budapest, Baross u. 13, Hungary (Received November 30, 1995) Abstract: A multivariate analysis of distance measurements (total length, posterior chord length, anterior chord length, blade length, basis length, guard length, total width and length of the perpendicular from the anterior chord to the lowest point of the curve of the blade) of the rostellar hooks of more than 18 taeniid species was carried out using an automated distance measuring method by personal computer. On the basis of discriminant analysis of 8 morphometric characters four other Taenia spp. are described. A considerable distance has been found among T. taeniaeformis, T. parenchymatös a and the T. brauni - T. serialis group, but the other species are also far from one another and may be classified into more than one genus within the subfamily Taeniinae.

In spite of this fact, the systematics and taxonomy of taeniid tapeworms at family, genus and species level are controversial. Detailed reviews of the taxonomical position of taeniids can be found in the monographs of Murai et al (1993) and Rausch (1994). Abuladze (1964) established two subfamilies within Taeniidae: Taeniinae comprising 11 genera and Echinococcinae consisting two genera. Verster (1969) placed the other genera in synonymy with Taenia. Rausch (1985) established two genera for the subfamily Taeniinae, Taenia Linnaeus, 1758 and Insinaurotaenia Spassky, 1948, and replaced the genus Alveococcus Abuladze, 1960 by the genus Echinoccus Rudolphi, 1801 in the subfamily Echinococcinae. Schmidt (1986) accepted the view of Rausch (1985) in his monograph.
