Abstract

Two new species of nematodes collected from soil around roots of weeds and Phaseolus sp. are described and illustrated. Torumanawa shinensis sp. n. is characterized by L = 1.4-1.6 mm, a = 42.2-54.2, b = 4.3-4.8, c = 38.2-50.3, c’ = 1.3-2.0, V = 50.1-52.5, expanded lip region, ventrally curved odontophore, amphidelphic females with unsclerotised vagina, and convexconoid tail with slight dorsal depression near rounded tip. Mylodiscus mognus sp. n. is characterized by L = 0.85-1.0 mm, a = 32.5-32.8, b = 3.7-4.4, c = 33.8-42.1, c’ = 1.4-1.5, V = 47.9-50.9, odontostyle 9-10 μm long, abrupt pharyngeal expansion, pre-rectum length 1.2 times anal body diameter, and tail longer than one anal body diameter.
