Two new nematode species, Rhabdochona salgadoi sp. n. and Spinitectus humbertoi sp. n., are described on the basis of specimens recovered from the intestine of Profundulus labialis (Günther) (Cyprinodontidae) from a brook near Inzcuinatoyac (the Pacific Ocean basin), Guerrero, Mexico. Rhabdochona salgadoi is characterised largely by the presence of 16 anterior teeth in the prostom and their arrangement, shape of the oral opening, absence of papilla-like structures on the margin of oral aperture, broad distal tip of the larger (left) spicule bearing a membrane, and by the tail tip of females (ending in a terminal formation bearing small cuticular processes). Spinitectus humbertoi is noted for possessing a characteristic spination of the cuticle separated into 4 longitudinal sectors, more or less regularly spaced rings with small variation in size and number (36-38 in first ring) of spines in the visible rings, and for the situation of the excretory pore between the seventh and the eighth rings of spines.
