A note on Lagochilascaris from the cat in Argentina

Abstract

Specimens of nematodes from the stomach, oesophagus and trachea of the cat, previously reported and described by Led et al. (1968), were found to resemble L. major more closely than other species in the genus. In the shape of the interlabia and the number of pits on the surface of the eggs, they conformed to this species. Accordingly they were identified as L. major although they differed from L. major in the width of the lips in relation to the postlabial collar and their more slender appearance, especially in the tail region. This is the third report of L. major and extends the host range and geographical distribution of this species.
