Adult specimens or parts of specimens of Wuchereria were recovered from the lymphatic systems of a Kra monkey (Macaca irus) (1), domestic cats (4), a dog (1) and a Slow Loris (N. coucang), from areas of endemic human filariasis in Pahang, Malaya.

Morphological studies on this material revealed a new species, herein named W. pahangi, in the dog and in one cat; a species in the Kra monkey which is close to and probably identical with adults of W. malayi as described by Bonne el at. (1941) from man in Indonesia; but its relationships, and also those of the species from man in Indonesia, with the W. malayi described by Rao & Maplestone (1939) in India need further investigation. Three cats harboured a species which is close to that in the Kra monkey but its identity is sub judice until further material is available. Fragments only of a female worm, which included the tail, were recovered from the Slow Loris. It is thought that this material may be the new species W. pahangi.
