Abstract

Seven new species of Dorylaimid nematodes collected from the farm of the Indian Agricultural Research Institute, New Delhi are described and illustrated. Discolaimoides teres sp. n. is distinctive by having L=1.l-1.3 mm, a=34.3–40.1, b=3.9–4.3 and V=43.5–46.1 and D. spatiolabium sp. n. by L=1.3–1.7 mm, angular expanded set off lip region, a=44.7–54, odontostylet=11–12 μm. Discolaimus laksi sp. n. is characterized by L=0.81–1.09 mm, odontostylet= 15–16 μm, odontophore=17-l8 μm and D. rotundicaudatus sp. n. by L=0.82–0.9 mm, odontostylet=14–17 μm and odontophore=16-l9 μm. Leptonchus neobaccatus sp. n. can be separated by having rectum=3/4 anal-body width, prerectum=3 vulval-body-widths anterior to vulva and V=55–64. Tylencholaimellus sagerus sp. n. is characterized by a=33–34, c=29.5–37.8, V=40–42 and odontostylet =8–9 μm while Tylmcholaimus rumjhumi sp. n. by a set off constricted head, cuticularized vagina and absence of males.
