Family Paruterinidae Fuhrmann, 1907 Genus Notopentorchis Burt, 1938 Notopentorchis iduncula (Spassky 1946) Spassky et Spasskaja, 1959 Specimens studied: One scolex and numerous fragments (of at least 3 specimens) in Canada balsam whole mounts (2 slides), HNHM No. E2479. Description: Fragments with maximum width 539 at level of pregravid proglottides. Scolex elongate, with maximum diameter of

309 (n = 1) at the middle of suckers. Rostellum (Figs 4G-H) discoid, with diameter of 113 and with strong musculature. Rostellar hooks 44 (n = 1) in number, in two distinct rows (with two exceptions where single hooks occur in intermediate position); anterior hooks 27 - 29 (av. 27.4, n = 3) in length, posterior hooks with length 29 - 30 (n = 2). Suckers with weak musculature, slightly oval, with diameter of 102 - 109 (av. 106, n = 4). Proglottides (Figs 4 I-K) craspedote, wider than long except when pregravid and gravid. Genital pores irregularly alternating in short series. Genital atrium simple, infundibular. Genital ducts ventral to osmoregulatory canals. Testes 4 (n = 2), 5 (n = 7) or 6 (n = 1) in number, encircling vitellarium, ovary and uterine primordium dorsally. Cirrus-sac thin-walled, lateral to or overlapping poral osmoregulatory canals, pyriform or flask-shaped, 64 - 75 x 30 - 36 (av. 70 x 33, n = 10). Vitellarium compact, median, near posterior margin of proglottis. Ovary transversely elongate, reniform or of irregular shape, compact. Seminal receptacle fusiform, elongate. Uterus spherical; paruterine organ wider than long, anterior to uterus. Proglottides with fully developed eggs not available. Remarks: N. iduncula was recently redescribed and discussed by Georgiev and Bray (1991). The aim of the present brief description is to document the first record of this species in Hungary rather than to provide taxonomic comments. The host range of N. iduncula includes four species of the genus Apus (A. apus, A.pacificus, A.paliidus and A. affinis). It is widespread throughout the Palaearctic region from Britain and Morocco to the Pacific coast of Asia (for a survey see Georgiev and Bray 1991). ACKNOWLEDGEMENTS We are grateful to Dr F.V. Bona for kindly permitting us to see a part of his unpublished manuscript, to the staff of the Parasitic Worms Division at the Natural History Museum (London) for the access to the types of Pseudangularia spp. during a visit funded by the European Economic Community, and Dr D.I.Gibson and Dr R. A Bray for reading the manuscript. Mr P. Peev provided valuable help with the preparation of the photographs. This investigation was completed with the financial support for one of the authors (B.G.) by the National Scientific Research Foundation of the Republic of Bulgaria, grant B - 44/1991.
