| Summary: | Paranoplocephaloides Gulyaev, 1996 (Fig. 3) Diagnosis: Strobila fairly short and thin. Scolex large, distinct from anterior strobila. Suckers prominent, directed anteriorly. Neck (unsegmented region) present. Proglottides craspedote, wider than long. Genitalia single. Genital pores irregularly alternating, positioned in middle of proglottis margin or slightly posteriorly. Genital atrium weak; genital papilla absent. Genital ducts cross osmoregulatory canals dorsally. Internal and external seminal vesicles present. Cirrus sac short, overlapping or extending slightly across ventral longitudinal canal. Retractor muscle of cirrus sac absent. Testes arranged in single transverse group in antiporal part of proglottis, may overlap or extend slightly across antiporal ventral longitudinal canal. Ovary large relative to proglottis size, transverse, sparsely lobed, median or slightly poral. Vagina short, overlapping ventral longitudinal canal, enters genital atrium posterior or postero-ventral to cirrus sac. Early uterus transverse tube in anterior part of proglottis, ventral to testes, overlapping or crossing longitudinal osmoregulatory canals ventrally and bilaterally; poral end terminates anterior to cirrus sac. Fully developed (pregravid) uterus sparsely sacculated with wide anterior and posterior sacculi that are usually pressed against adjacent sacculi throughout their development; distinct transverse trunk absent. Testes persist after resorption of female glands overlapping developing uterus. Pyriform apparatus present. Parasitic in cricetid (Arvicolinae) rodents. Type-species: P. schachmatovae Gulyaev, 1996; holotype No. 153, MIES, Novosibirsk, from the root/tundra vole Microtus oeconomus (Pallas). Other species: P. r a u s c h i (Genov, Georgiev & Biserkov, 1984) Gulyaev, 1996 (syn. Anoplocephaloides rauschi Genov, Georgiev & Biserkov, 1984). Remarks. Paranoplocephaloides belongs to the group of genera characterized by an anteriorly positioned early uterus that overlaps or extends ventrally across ... |
