Morphology and Anatomy:

 Meloidogyne triticoryzae is similar to M. graminis from which it can be differentiated by its distinctly smaller J2 (380-425 µm), females (330-480 µm) and males (1100-1590 µm), characteristic perineal pattern without lateral lines, more slender J2 (a = 36.4) with greater b′ (8.7) and a slightly larger EPST ratio of female (1l.5). (Gaur et al., 1993)
