The description and figures of two new species of nematodes of the genus Tylenchorhynchus Cobb, 1913 are given. T. variannus sp. n. is characterized by an asymmetrical position and variation of the width of cuticular rings in the trophic, genital and caudal parts of the body. It differs from T. irregularis Wu, 1969 in the shape of the stylet and tail and in the number and width of the tail rings. T. chirchikensis sp. n. differs from allied species by the protrusion of the cuticle into the body around the vulva, length of the ovary, structure of the head capsule, stylet and tail and by the ratio between the tail length and body width of the anus.
