A new genus and species of the family Paradoxosomatidae from southern part of West Bengal, India is described. The new genus Manikidesmus gen. n. is diagnosed by combination of following characters: reduced paranota, distinct pleural keel, unpaired sternal lamella on 5th sternite, prefemur with setal brush, setal brush on tibia and tarsus in male, lamina medialis long straight with a curved hook, expanded post femoral lamina with a spine and tibiotarsus with a spine on the distofemoral process.
The genus is distinguished from its Indian congeners by one or more diagnosed characters. In Manikidesmus suriensis, sp. n. tibia and tarsus bear setal brush in male (vs. absent in Oxidus and Chondromorpha), gonopod femur short, flat and without post femoral demarcation (vs. long, thin cylindrical with post femoral demarcation in Polydrepanum and Orthomorpha), tibiotarsus of gonopod long and a spine on the distofemoral process (vs. short and without spine in Anoplodesmus). In Kronopolites, coxa of gonopod densely bristled, collum with two rows of long bristles, femur long, slender and with a spine. All these characters are absent in the present genus. In Streptogonopus, gonopod femorite is distinctly demarcated from post femorite region and solenomere is twisted with solenophore but in the present species, femorite is not be separated from post femorite region and solenomere is free from solenophore.
