Kikinda: 13.7. 1979, 3250/4; 24.10.1980, 4177/60; Zombor: 27.10.1979, 3516/26, 2536/3; 12.7.1980, 4274/5; Zrenjanin: 13.5.1977, 1110/63, 1137/2; 27.3.1980, 3819/4. Description: Anterior end oval with four well-developed submedial papillae. Distance between amphids infernales 0. 042-0. 049 mm. Lateral alae present.

Notes: HRISTOVSKI (1979) mentioned this species from three rodent species (Apodemus sylvaticus, Mus musculus and Rattus norvegicus). According to the present state of knowledge in all probability three Syphacia species masqueraded under the name S. obvelata (see QUENTIN, 1971; TENORA and MÉSZÁROS, 1975; GENOV and JANÍEV, 1980). 6.
