The handle and the balade as well as the guard are of the same length (0.012-0.013), the tip of the guardlobe 0. 005-0. 007 wide and there is a small there is a small 3 pm deep notch in its middle (Figs 16-17). Testes in triangle or in one line, two aporal and one poral. Cirrus finelly spinose, cirrus sac 0.07-0. 10 x 0.02, vesicula seminalis interna 0.015 by 0. 010, a little vesicula seminalis externa present. Ovary in poral side 0.06 x 0.012, vitelline gland 0. 025 in diameter. The thin-walled vagina widens to form a small seminal receptacle. Uterus saccular, containing over 20 (40) eggs, and forming an egg capsule (1 in each segment) 0. 11-0. 14 x 0. 16-0.18, the wall of capsules in 5 jum thick. Eggs measure 0. 044 x 0.031, the embryo 0. 020 x 0. 030, the embryonal hooks are 0.010 long. Triodontolepis skrjabini Spassky et Andrejko, 1968 (Figs 29-34). Hosts: Neomys fodiens and N. anomalus. - Localization: small intestine. - Intensity: 1-10 specimens. - Extensity: 6%. Material examined: 34 specimens from 9 N. fodiens and 5 N. anomalus in seven localities were found. Host: Neomys fodions: Slovakia, Cergov Mts, Lenartov, Vecny potok, 10 November, 1981, leg. MURAI, 1 specimen; Stolické vrchy Mts, Chyzné, 13 November, 19 82, leg. MURAI, 1 specimen; Vel'ka Fatra Mts, Harmanec, Bystrická dolina, 28 August 1979, leg. DUDICH, 2 specimens, Hungary, Mátra Mts, Mátraalmás, Szuhai patak (valley), 27 June, 1984, leg. MÉSZÁROS, 22 specimens; Roumania, Gilau Mts, Baisoara valley, 11-15 August, 1971, leg. MÉSZÁROS, 3 specimens. Host: Neomys anomalus: Hungary, Bükk Mts, Nagyvisnyó, Bán patak(in the valley), 15-16 October, 1983, leg. MÉSZÁROS, 3 specimens; Börzsöny Mts, Királyháza, 9 October, 1983, 2 specimens, leg. MÉSZÁROS. Metric and morphological data of T. skrjabini based on our material: Small hymenolepidid species. Mature specimens 10-15 long, 0..3 wide. Number of segments 200-300 (of 272 segments 32 were found to contain mature egg capsule), always wider than high. Diameter of scolex 0. 220-0. 370, length 0. 200-0. 330. Diameter of the four suckers 0. 085-0.120. Diameter of the muscular rostellum 0. 06-0. 08, height 0. 05-0. 07, the rostellar sac 0. 250 x 0. 150. There are 10 (in 1 case 11) hooks of bifurca-type on the rostellum, 0. 025-0. 027 long, basis 0.022-0.025, handle 0.012, blade 0.013, guard 0. 012-0. 013 long, the tip of the guard-lobe 0.010 wide, and there is a 6 jum deep notch in its middle (Figs 29-30)1 Strobila slightly craspedot. The series of segments of various degrees of maturity clearly distinguishable. In mature segments the 3 testes arranged in a triangle, in strongly contracted strobila along a line. One testis porally, the other two aporally situated, 0. 025 x x 0, 0 50 large. The ovary is situated centrally or porally beneath the vitelline gland. The cirrus sac 0.080 x 0.020, there is a vesicula seminalis interna and externa. Cirrus finelly spinose. The thin-walled vagina opens behind the cirrus and there is a seminal receptacle. In postmature segments the uterus occupies the whole central field, surrounding the eggs in an egg shape and when in the eggs the embryonal hooks appear, this formation turns into a strongly chitinized capsule (Figs 32-34). Egg capsule 0. 100 x 0. 170 - 0. 160 x 230 in size, the thickness of the wall 3 jum. The eggs in the uterus (ca. 20 per segment) measure 0.044 x x 0. 035, the embryo 0. 023-0. 027 x 0. 017-0. 019, length of the embryonal hooks 0. 009. Note. The species has not been reported from elsewhere than its type locality (Moldavia, SPASSKY and ANDREJKO, 19 68). We now have evidence for its occurrence from the Gilau Mts and in the west in the Börzsöny Mts, and in the north to Lenartov (Cergov Mts).
