Catenotaenia henttoneni Haukisalmi & Tenora, 1993 (Figs 4 & 5) Material examined: 21 gravid specimens from the bank vole Myodes glareolus (Schreber) and 20 specimens from the red vole Myodes rutilus (Pallas) (Cricetidae, Arvicolinae) from northern Finland (Lapland). For the prevalence and ecology of C. henttoneni (as Catenotaenia sp.), see Haukisalmi & Henttonen (1990, 1993a, b). Site: Usually the middle third of the small intestine (jejunum). Deposited voucher specimens: USNPC 102583 and 102585 from M. glareolus from Pallasjärvi, Finland (68.02528o N, 24.15944 o E), USNPC 102584 and 102588 from M. rutilus from Pallasjärvi, Finland, USNPC 102586 and 102587 from M. rutilus from Kilpisjärvi, Finland (69.05222o N, 20.78639o E), USNPC 102582 from M. glareolus from Monte Bondone, Trentino, Italy (46o04' N, 11 o08' E). Description: Length of fully gravid specimens 62–136 mm (91 mm, n=14); maximum width 1.0– 1.7 mm (1.30 mm, n=22), usually attained in pregravid proglottids. Number of proglottids 58–76 (68.6, n=14). Scolex small, 240–300 (274, n=9) wide, flattened dorso-ventrally, usually separated from neck by slight constriction. Scolex usually with more or less distinct apical cone or bulge. Neck 0.5–0.9 mm (0.63 mm, n=8) long, usually of roughly uniform width, 175–260 (229, n=8) wide immediately posterior to scolex. Suckers 105–138 (119, n=9) in diameter, directed laterally or antero-laterally, embedded within scolex. Proglottids slightly craspedote or "pseudocraspedote"; velum very short or absent. All proglottids widest in posteriormost part, which widens rather abruptly. Mature proglottids roughly as long as wide. Length and length/width ratio of proglottids increase posteriad; immature proglottids 290–720 (506, n=34) long, with length/width ratio of 0.50–1.09 (0.76, n=34); mature proglottids 800–1470 (1174, n=52) long, with length/ width ratio of 0.71–1.72 (1.12, n=52); fully gravid proglottids 2.7–5.1 mm (3.66 mm, n=19) long with length/ width ratio of 2.42–5.10 (3.42, n=19).
