Plectus glandulatus sp. n. has 917-1307 µm long body. strongly annulated cuticle; conspicuously large hypodcrmal glands: ovoid amphidial apertures; offset lip region; separate, globular, lips; thickly cuticularised. arcuate, cheilostomal walls: basal bulb with four to five paired denticulate ridges: a pair of pseudocoelomoeytes located posterior to the cardia and tail with a subtenninal spur and three pairs of caudal setae. Chiloplectus indicus sp. n. has 695-1041 pm long body: thick, transversely annulated, cuticle: three lateral incisures: markedly offset, narrow, lip region: lips with conical apices anil slightly raised papillae: inner margin of lips forming well cuticularised oral framework; prorhabdion as long as wide and comprising 20% of the stoma length; basal bulb with six pairs of denticulate ridges; paired pseudocoelomoeytes located posterior to the cardia. genital tract weakly developed and tail with one median spur and two pairs of caudal setae.
