Two new diplogastrid species, Diplogastrellus sikorai sp. n. and Fictor composticola sp. n., are described and illustrated. Another species, D. gracilis, is reported for the first time from India and is redescribed with an emended diagnosis and SEM details. Diplogastrellus sikorai sp. n. is characterised by relatively small-sized body (female: L = 0.49-0.65 mm, a = 24-30, b = 4.9-6.3, c = 2.4-2.8), with a prominent, upright, dagger-like dorsal tooth and well developed subventral ridge; pore-like vulva, large post-uterine sac; ventrally arcuate spicules with rounded capitula and rosethorn-shaped gubernaculum with proximal spur and lateral sleeves around the spicules. Fictor composticola sp. n. is characterised by medium-sized body, eight cheilostomal plates with 18-22 cheilostomal filaments; gymnostom and stegostom with serrated anterior margins; dorsal and right subventral stegostomal walls each bearing a more or less equal tooth; left subventral stegostomal wall with two adjacent serrated plates; males with weakly cephalated, slender, ventrally arcuate spicules; wedge-shaped gubernaculum with tapering proximal end and lateral sleeves surrounding the distal ends of the spicules; and nine pairs of caudal papillae.
