The new species is characterised by numerous testes, numbering 78 to 129 in several layers, situated mostly aporally to female glands, many of them behind the aporal lateral excretory canals, few anteriorly and some may overlap aporal and anterior lobes of ovary. Cirrus sac piriform, relatively long 94 to 117 by 225 to 258 pm, never across and behind poral lateral excretory canals. External seminal vesicle 40 to 66 by 410 to 503 um, tubular, covered by a layer of cells. Cirrus spined. Vagina 48 to 76 by 223 to 267 pm, open posteriorly to male pore, always shorter than cirrus sac, surrounded by thick cellular stripe, sleeve 78 to 129 pm in width, lumen 18 to 77 pm in diameter. Seminal receptacle big and long (291 to 373 by 847 to 949 pm), cross-striking osmoregulatory canals. Uterus at first aggregation of cells, transverse, dorsal, becoming later reticulate and developing anterior and posterior sacculation. In gravid segments, uterus situated bilaterally across and behind osmoregulatory canals. The new species is related to the species Paranoplocephala aquatica Genov, Vasileva et Georgiev, 1996 and to the species Aprostatandrya macrocephala (Douthitt, 1915). Key words: Paranoplocephala genovi sp. n., P. aquatica, Aprostatandrya macrocephala, host Ondatra zibethicus, Czech Republic INTRODUCTION Genov et al. (1996) described the species Paranoplocephala aquatica sp. n. including the materials reported by Genov (1964,1984) as Aprostatandrya macrocephala (Douthitt, 1915) or Paranoplocephala blanchardi (Moniez, 1891) and identified by Spasskii et al. (1951) as Aprostatandrya (A) macrocephala (Douthitt, 1915) Spasskii, 1949. Moreover, Genov et al. (Î996) put into the species/? aquatica Genov, Vasileva et Georgiev, 1966 the specimens recovered from Ondatra zibethicus and described by Tenora and Murai (1980)
