A SCANNING ELECTRON-MICROSCOPE STUDY OF SOME RICTULARIIDAE (NEMATODA)PARASITES OF IBERIAN MAMMALS

Morphological study of three species from the Rictulariidae family bel onging to the Rictularia genus-R. proni Seurat, 1915 - and to the Pter ygodermatites genus - P. affinis (Jagerskioald, 1904) and P. leiperi ( Ortlepp, 1961), isolated from the intestine of four hosts species from the Iberian Peninsula: the field mouse, Apodemus sylvaticus Linnaeus, 1758 (Muridae) (Rodentia); the red fox, Vulpes vulpes (Linnaeus, 1758 ) (Canidae); the stone marten, Martes foina (Erxleben, 1777) (Mustelid e) and the genet, Genetta genetta (Linnaeus, 1758) (Viverridae) (Carni vora). The description of the three species is supported by a morphome tric and a morphological analysis by means of scanning electron micros copy (SEM).
