Studies on soil nematodes of Manipur-VII: Tylencholaimus vanguimus sp.n. and Dorella papila sp.n

Two new species of dorylaims belonging to the genera Tylencholaimus and Dorella were recorded from soil around roots of Vanguireas spinosa and Gravilea robusta respectively. Tylencholaimus vanguimus sp.n. has body length 0.37–0.42 mm., a=20.1–23.3, b=2.5–2.8, c=29.1–32.6, odontostyle = 4.8–6.4 μm, expanded part of oesophagus 34–36% of the total oesophageal length, mono-prodelphic reproductive system and elongated hemispheroid tail. Dorella papila sp.n. is characterised by having 0.65–0.76 mm long body, lips with papillae, absence of disc, spear one to one-half times its head width, faint stiffening piece, mono-prodelphic reproductive system, presence of uterine sac and conoid to rounded tail terminus.
