The genus Lagenonema was established by Andrassy (1987) belonging to the subfamily Thornenematina e Siddiqi, 1969, famiily Thornenematidae Siddiqi, 1969 under the order Dorylaimida . He erected the genu s by differentiating it from Thomenema Andrissy, 1959 in having abruptly narrowed, bottle-shaped anterior region, well sclerotized spatulate cephalic framework, ventrally concave spear and smaller amphids. Jairajpuri and Ahmad (1992) did not agree with him and noted that Lagenonema was close to Thomenema. Gantait, Bhattacharya and Chatterjee (2010) however agreed with Andrassy's opinion that Lagenonema is a well defined, distinct genus.
