Pratylenchus similis
Khan, E. and Singh, D.B., 1974
 5 ?? (Paratypes):  L = 0.44 mm (0.40-0.50); a = 26.2 (20.7-31.7); b = 3.99 (3.5-4.5); c = 14.8 (11.1-23.7); V = 80 (76-85); Spear = 12 u (12-13).
 Female (Holotype):  L = 0.50 mm; a = 31.3; b = 3.8; c = 23.7; V = 78.0; Spear = 13 u.
 Male (1):  L = 0.42 mm; a = 20.5; b = 3.9; c = 21.4; spicule = 14 u; gubernaculums = 6 u; Spear = 12 u.
 4 ?? (Jadid):  L = 0.45 mm (0.44-0.47 mm); a = 28.0 (24.7-33.5); b = 4.8 (3.9-5.8); c = 15.9 (13.0-24.7); V = 80 (78-81); Spear = 13-14 u.

 Female curved ventrally when killed.  Lip-region with two annules.  Posterior edge of cephalic frame-work strongly sclerotized extending posteriorly into body for about three annules.  Spear knobs flattened.  Excretory pore located in level with oesophago-intestinal junction.  Lateral field with four incisures.  Ovary single, anteriorly outstretched with single row of oocytes; Spermatheca oval with sperms; post uterine sac over two anal-body-widths long.  Tail conoid with rounded terminus bearing 16 (16-18 annules in paratypes), tail tip annulated.  Phasmids located twelve annules posterior to tail terminus.
 Male:  Slenderer than the female.  Head comparatively more high than the female.  Excretory pore located slightly anterior to the oesophago-intestinal junction.  Testis outstretched with spermatosites arranged in single row towards proximal end while double in the distal part.  Spicules arcuate; bursa caudal, crenate.  Phasmid located in posterior third of tail.
 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.
