Female: Body length 32-45 mm, maximum width 0.85-1.70 mm. Pharynx 0. 16-0. 18 mm deep. Muscular part of esophagus 0.21-0. 29 mm, glandular part 3.6-3.9 mm, long. Nerve ring 0.58 mm, excretory pore 0.61 mm, and deirids (slightly asymmetrical) 0. 48-0. 50 mm, from anterior end. Vulva opening in anterior part of body, in one case 18. 4 mm from anterior end. Distance of anus 0. 31 mm from posterior end. After studying the morphogenetic changes of the head portion of M. muris

, QUENTIN (1970) established a new subfamily (Mastophorinae) for this species. Primarily a parasite of rodents, occasionally that of carnivores in the Holarctic. PROKOPIC and GENOV (1974) published a list of literature regarding this species. 7. Syphacia petrusewiczi Bernard, 1966 (Fig. 6A-B) For distribution in Hungary see Table 1 and map. - Localization: coecum. - Extensity 1.8%, intensity 3-106 specimens. Head end laterally elongated. Lips withouth countours. Four submedial papillae near amphids. Rough cervical alae present, ending near excretory pore. Fig. 6: Syphacia petrusewiczi Bernard, 1966 A = Anterior end of female, en face view. - B = Anterior end of female Female: Body length 3.30-4.40 mm, maximum width 0.28-0.30 mm. Distance between amphids 0.040 mm. Esophagus length 0. 28 mm. Nerve ring 0.12-0.13 mm, excretory pore 0. 34-0. 37 mm, and vulva 0. 41-0. 47 mm, from anterior end. Deirids at level of nerve ring. Tail length 0. 44-0. 46 mm. Eggs 0. 103-0.105 mm long by 0.032-0.035 mm wide. Without exception, only females were found in the material studied. Detailed description and distributional data of the species are in the publications of QUENTIN (1971) as well as in TENORA and MÉSZÁROS (1975). According to our present knowledge, C. glareolus is its only host.
