Holotype: Female on Type Slide No. 547 deposited with the National Nematode Collection, Division of Nematology, Indian Agricultural Research Institute, New Dehli-12.
Paratypes: 4 females and one male on Slide No. 548-551. Other data same as for holotype.
Type habitat and locality: From soil around roots of Rose at Lucknow, U.P.
Diagnosis and relationship: Pratylenchus similis sp. n. comes close to P. flakkensis Seinhorst, 1968 from which it differs by having a shorter spear, (spear 17 u in P. flakkensis), lesser number of tail annules (18-24 for P. flakkensis) and a longer posterior uterine sac, (post uterine sac slightly over one anal body width in P. flakkensis).
Specimens collected from soil about the roots of sorghum at Jadid have been identified as P. similis.
