The Taeniids detected (T. mustelae Gmelin, 1780 = T. tenuicollis Rudolphi, 1819) in the intestine of several weasels were identified by the morphology and morphometry of the scolex. The most important morphometric data (n=5) are given as ranges in micrometer with the mean in parentheses: a) scolex: 268-345 (320); b) suckers: 110-141 (125); c) rostellum 55-102 (85) wide, with 2 rows of 27 hooks; d) the hooks of the inner row are little longer (20-24) than the hooks of the outer row (20-21 ). Our material shows a great similarity to the specimens of 71 tenuicollis Rudolphi, 1809 cited by Prokopic (1965) parasitizing Putorius putorius, Martes foina and Mustela erminea in Czechoslovakia. The nomenclature of T. tenuicollis has often been widely discussed (Freeman 1956, Abuladze 1964, Verster 1969, Tenora and Vanek 1969, Murai and Tenora 1973, Murai 1982, Rausch 1985). We have adopted the opinion of Freeman (1956) who concludes that T. mustelae has priority over T. tenuicollis. On the other hand, recently, Iwaki et al. (1995) have also cited T. mustelae parasitizing M. nivalis in Japan. Aonchothecaputorii (Rudolphi, 1819) Localities: provinces of A, AST, AV, B, BU, CAN, CC, CR, Gl, L, LE, M, P, SG, SO, TE, VA, VIZ and Z. Prevalence: 19.0%. Invasion intensity: 1 - 50. A. putorii is a gastric nematode, which mainly parasitizes Mustelids (Miquel 1993). Its systematic position is confusing and it has been discussed by several authors, both at specific and generic level (Fahmy 1964, Wakelin 1968, Butterworth and Beverley-Burton 1980, Moravec 1982, Mas-Coma 1984). We agree with the classification proposed by Moravec(1982). Trichinella sp. Locality: province of Avila (AV). Prevalence: 0.6%. Invasion intensity: indetermined. In the first intestinal portion of a weasel we detected some small nematodes (ingravid females) classified as belonging to the genus Trichinella Railliet, 1985. Following Pozio et al. (1992) the helminths could only be classified at a genus level. Strongyloides mustelorum Cameron et Parnell, 1933 Localities: provinces of A, AST, AV, B, BU, CAN, CC, CR, L, LE, LR, M, P, PO, SG, SO, TO, VA, Z and ZA. Prevalence: 20.8%.. Invasion intensity: 1 - 5. S. mustelorum is a nematode, which is frequently detected in the small intestine. Its determination could be easily carried out on the basis of the original description (Cameron and Parnell 1933) and its recent redescription (Kharchenko and Tkach 1992). Molineus patens (Dujardin, 1845) Localities: provinces of A, AST, AV, B, C, CC, CAN, CR, Gl, L, LE, LR, M, N, PO, SG, T, TE, TO, VIZ, Z and ZA. Prevalence: 39.3%. Invasion intensity: 1-102. In our study the most frequent parasitic species was M. patens. This intestinal nematode could be determined according to the paper of Durette-Desset and Pesson (1987). The suprageneric systematic position of this species has recently been established by Durette-Desset and Chabaud (1993).
