Matskási, I.: The systematico-faunistical survey of the trematode fauna of Hungarian bats. I.
A fusiform or oval Trematode. Length of body 0.610—0.700, width of body 0.375—0.400 mm. Cuticle smooth. Subterminally situated oral sucker round, 0.050— 0.060x0.055—0.062 mm. Pharynx small, round, 0.015—0.030x0.030—0.037 mm. Oesophagus long, 0.050—0.052 mm, branching into two short caeca. These latter only approaching but not reaching anterior surface of testes. Ventral sucker round, located centrally, 0.060—0.082x0.080—0.100 mm (invariably larger than oral sucker). Two slightly ovoid testes situated symmetrically on both sides of body, right testis 0.112-0.137x0.082-0.100 mm, left testis 0.101-0.125x0.080-0.087 mm. Well developed prostata complex, surrounded by bifurcation of caeca, containing coiled cirrus and prostata glands. Ovarium a slightly irregular oval, 0.075—0.101x0.050—0.097 mm, located near ventral sucker, between right testis and acetabulum. Position of vitellaria characteristical, formed by two groups of 4—6 follicles (DUBOIS observed 7—9 follicles, HURKOVÁ also 7—9; I never found more than 6). Follicles lying postcaecally on anterior portion of testes, dorsally slightly covering them, occasionally adjacent to sides of body. Whorled uterus filling entire posterior half of body, behind testes. Eggs brown, 0.015-0.020x0.005-0.010 mm. My material consists of the following specimens : Myotis daubentoni, 1, Abaliget Cave, 9 Febr., 1957, 6 spec. Subfamilia: Fycnoporinae YAMAGUTI, 1958 Genus: Pycnoporus Looss, 1899 Pycnoporus heteroporus (DUJARDIN, 1845) (Fig. 11) Syn.: Distoma heteroporum DUJARDIN, 1845; Pycnoporus skarbilovichi SHAXDIBIN, 1948; Pycnoporus treljudovi SHALDIBIN, 1948. Hosts : Pipistrellus pipistrellus, Pipistrellus kuhli, Vespertilio murinus, Eptesicus nilssoni. Distribution: Hungary, France, England, Czechoslovakia, Egypt. An elongate, relatively large-sized, lanceolate Trematode. Length of body 0.492—1.378 mm, width of body 0.270—0.400 mm. Anterior part of body narrower than posterior one. Cuticle finely and densely spinose in anterior part of body. Terminally situated oral sucker small, round, 0.020—0.057x0.036—0.057 mm. Pharynx muscular, emitting long oesophagus branching into two short but voluminous caeca. Caeca not extending further posteriorad than anterior part of ventral sucker. This latter strongly developed, robust, wide, 0.093—0.208x0.104—0.228 mm. Testes situated postacetabularly and symmetrically, left testis 0.098—0.104x0.062—0.093 mm, right testis 0.109—0.124x0.008—0.093 mm, frequently covered by uterus. Prostata complex lying between ventral sucker and caecal bifurcation, 0.052—0.072 x 0.072-0.093 mm. Oval ovarium situated between ventral sucker and left testis, 0.072—0.083 X 0.062—0.104 mm, with adjacent and conspicuous receptaculum seminis. Egg-filled whorls of uterus occupying posterior half of body, then, extending anteriorad on right side, terminating in front of ventral sucker. Genital pore also opening here. Eggs dark yellow, 0.015 x 0.005 mm. Two vitellary groups consisting of some few follicles. Between ventral sucker and testes, 6 follicles on right, and 7 on left, side of body.
