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.
