Tenora, F., Gubányi, A.; Eszterbauer, E.: Morphological investigation of Mesocestoides (Cestoda, Mesocestoididae) species parasitizing Vulpes vulpes in Hungary

The measurements were analysed by descriptive statistics using Statistica 5.0 program package and are given in micrometres, except for strobila length, which is given in millimetre. Results and discussion Two main groups of distance measurements can be distinguished. More than 50 percent of the investigated measurements (CD1-2, AD3-4, AD5-6, BD1-2, BD3-4, BD5-6, VD1-2, VD3-4, UD1-2, UD3-4, OD1-2, OD3-4, DD1-2, DD3-4, DD1-3, DD2-4, DOl-2, PD1-2, PD3-4) did not show any discriminating characteristic. As shown on Fig. 1, frequency distribution of CD3-4, TD1-2, VD5-6, AD1-2, UD1-3, UD2-4 can be characterised by two well separated peaks. After dividing the samples into two groups using the width of cirrus pouch (CD3-4) and the diameter of testes (TD1-2) a significant difference (P<0.05) has been found between them. The length and width of paruterine organ of two specimens show extremely small values compared to the other samples. Extreme values were also found for the length of mature segment (128 and 1233, respectively) among the specimens. Mesocestoides lineatus (Goeze, 1782) Railliet, 1893 (Figs 7,9, 11, 13) (syn.
