Abstract: Travassosinema bengalensis n. sp. is described from the hind gut of the spirobolid millipede, Trigoniulus corallinus (Gervais) from West Bengal, India. Females of the new species differ from the only known Indian species, T. travassosi Rao, 1958 by several characters namely tail length, length of oesophagous, size of egg, extension of umbraculum etc. It is very similar to other three species of Travassosinema, T. travassosi, T. thyropygi Hunt, 1996 and T. claudiae Morffe & Hasegawa, 2017 as all of them lack lateral alae and body contraction posterior to vulva. Except T. claudiae, it differs from all other species from millipedes by longest tail length (60% SL) and differs from T. claudiae by shorter oesophagous length and location of vulva. A new method for presentation of morphometric data (in percentage to standard length) in nematode is suggested. On the basis of phylogenetic analysis, it is suggested that umbraculum bearing genera, Indiana, Pulchrocephala should be excluded from the family Travassosinematidae.
