Abstract :The genera Loxogenes Stafford, 1905 & Loxogenoides Kaw, 1945 under Lecithodendriidae: Trematoda had been controversial genera as both genera met suppression by various authors from time to time where as others supported the validity of at least one (ie. The genus Loxogenes.)

Varma & Sahay, 1985 modified the generic diagnosis of the genus Loxogenes while describing Loxogenes staffordii from Rana tigrina at Pathsala Assam. Varma, 1982 considered Loxogenoides a nomenclatural change of the genus Loxogenes & applied the rule of priority in retaining the genus Loxogenes. The present authors have valid reasons in considering the geneus Loxogenes Stafford, 1905 valid whereas have sufficient grounds to suppress the genus Loxogenoides kaw, 1950 & thus accord support to the views of Tubangui, 1928; Fuhrmann, 1928; Krull, 1936 Yamaguti, 1958: Yamaguti, 1971 & Varma 1982 who also supported the existence of the genus Loxogenes but without any arguments.
