Extremely small nematodes. On the surface of body there are longitudinal cuticular crests (crête) with inner chitinized frame. These crests are more developed at the ventral side. Head end surrounded by a vesicle. Male: Body length 2. 20-2. 50 mm, maximum width 0.060-0.070 mm. Esophagus length 0.280.33 mm. Nerve ring 0.13-0.17 mm, excretory pore 0.17-0.21 mm from anterior end. Bilobed, symmetrical bursa. Externo-dorsal and dorsal rays with a common trunk, externo-dorsal ray diverging nearest its base, then the dorsal ray bifurcates and both branches bifurcate again near the margin of bursa. Postero-lateral and medio-lateral rays diverging from a common trunk and also the ventral rays, however, these latter are less developed. Prebursal papillae absent.
