hooks show 12.5% agreement with those of T. "hydatigena" (MHNG-1

5/40) and T. kotlani (6.3 %), too. The other T. acinonyxi (MHNG-94/20) can be discriminated from all other tapeworms at a moderate level (small hooks: 94.1 %, large hooks: 72.7 %). The small and large hooks of T. brauni (MHNG-1

23/81) correspond to those of the other T. brauni (MHNG-123/82) in 50 and 75.0%, respectively. The latter specimen shows better separation (small hooks: 90%, large hooks: 83.3%), and its small hooks are similar to those of T. serialis in 10%, while its large hooks show 8.3 % agreement with those of the other T. brauni and T. ovis, respectively. An excellent separation (100%) has been observed for the small hooks of both specimens of T. selousi (MHNG-124/28 and MHNG 124/29). The large hooks of MHNG-124/28 T. selousi can also be distinguished in 95.0 % from the others. The large hooks of MHNG124/29 T. selousi have a 93.3 % correct classification result and show only 6.7 % agreement with the hooks of the former specimen (MHNG 124/28). Unfortunately, it is not clear whether those were recovered from the same host individuals or arose from different host specimens. Discrimination of the small and large hooks of T. martis (HNHM13048) is also at a high level (100 %) on the basis of 8 morphological character. Surprisingly, the large hooks in the MHNG-1

5/40 mount named T. "hydatigena" show 100 % segregation from all of the specimens included in the analysis. This mount contains only one small hook, which is classified as T. "pisiformis" (HNHM-7835/132). The small and large hooks of T. "hydatigena" no.: MHNG-1

5/41 can be distinguished in 75 and 66.7 %, its small hooks are in agreement with the small hooks of T. "pisiformis" (HNHM 7835/132) and the large hooks are similar to those of T. kotlani. Hooks in the MHNG123/25 mount, identified as T. "hydatigena" and recovered from C. familiáris which originating from Iceland can be segregated at a high level (100 %) from the other species and specimens. On the other hand, the separation of the small and large hooks of T. hydatigena (HNHM-13202 mount) is at a low level (28.6 and 81.8 %, respectively). T. parenchymatosa as T. laticollis can be very well (100 %) differentiated from the other specimens by the small and large hooks. The differentiation rate of the small and large hooks of Taenia kotlani from the other specimens is 78.9 and 82.4 %, respectively. The adult hooks of T. multiceps represent a higher discrimination rate than do larval one, however, the large and small hooks in MHNG-1

23/26 mount can be distinguished in 84.6 and 76.9 %, respectively. Generally, the small hooks of larval forms are similar to those of the groups of T. "hydatigena", while its large hooks are in agreement with those of T. solium. Classification of the hooks of T. pisiformis specimens also seems to be interesting. Small and large hooks of T. pisiformis labelled MHNG-124/30 can be differentiated at 90 and 100 % level, respectively. Except for those of T. pisiformis labelled HNHM-7835/

132, the small hooks of the remaining T. pisiformis specimens are close to one another. At the same time, their large hooks show a considerable segregation. Small and large hooks in the mount HNHM-7835/132, identified as T. "pisiformis", can be well distinguished from the other hooks (88.9 and 92.3 %, respectively). The two specimens of T. regis can be separated from one another and from all other specimens at a high level (100 %) on the basis of the small and large hooks, respectively.
