AbstractTwo new plectid species from India are described and illustrated. Plectus glandulatus sp. n. has 917-1307μm long body; strongly annulated cuticle; conspicuously large hypodermal 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 pseudocoelomocytes located posterior to the cardia and tail with a subterminal spur and three pairs of caudal setae. Chiloplectus indicus sp. n. has 695-1041μm long body; thick, transversely annulated, cuticle; three lateral incisures; markedly offset, narrow, lip region; lips with conical apices and 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 pseudocoelomocytes located posterior to the cardia, genital tract weakly developed and tail with one median spur and two pairs of caudal setae.
