Labronema nepalense n. sp. is 1.40-1.53 mm long; with a= 26-29; b = 3.8-4.0; c = 67-74; V = 58-59; odontostyle = 23-25 μm; and is closely related to L. ruttneri and L. octodurense. L. pararapax n. sp. is 1. 53-1.85 mm long; with a = 26-31; b = 4.0-4.8; c = 43-63; V = 56-59; odontostyle = 25-27 μm; spicules = 57-65 μm and is close to L. rapax and L. mauritiense. Oriverutus hastus n. sp. is 0.87-1.01 mm long; with a = 30-44; b = 3.0-3.8; c = 18-23; V = 49-50; odontostyle = 13-14 μm; spicules = 32 33 μm and is close to O. hastatus and O. arcuatus. Aporcelaimellus baqrii n. sp. is 1.82-2.05 mm long; with a = 28-32; b = 3.4-3.8; c = 63-67; V = 53-57; odontostyle = 24-26 μm; spicules = 63 μm and is close to A. calmus, A. conoidus and A. hylophilus. Amphidorylaimus flagellicauda, Prodorylaimium brigdammense, Ecumenicus monohystera, Labronema mauritiense, Lordellonema porosum, Poronemella porifer, Crateronema aestivum, Aporcelaimellus amylovorus, Aporcelaimellus obscurus and Aporcelaimellus laevis are reported for the first time from India with additional data. Males of Amphidorylaimus flagellicauda, Aporcelaimellus amylovorus and Discolaimus tenax are described for the first time.
