Two new dorylaim species belonging to the genus Aporcelaimellus Heyns, 1965 (Nematoda: Aporcelaimidae) and Paractinolaimus Meyl, 1957 (Nematoda: Actinolaimidae), collected from the rhizospheric soil of banana (Musa paradisiaca L. cv. Kanthali) from Paschim Medinipur district, West Bengal, India are described. Aporcelaimellus subhasi n. sp. closely resembles A. chauhani and A. coomansi Baqri et Khera, 1975 but differs significantly in total body length and in the values of other measurements (a and b in A. chauhani and a, c and V in A. coomansi). The tail length, tail shape and the shape of cardia are also different. Paractinolaimus shamimi n. sp. shows similarities with P. aruprus Khan et al., 1994, P. macrodentatus Sukul, 1967 and P. filipjewi (Schneider, 1935) Meyl, 1957 in having a long tail but differs from these species in total length, tail length, dentition, structure in the vestibule, shape of cardia, and in other characters such as a, c and V.
