Two new species of mononch (nematoda: mononchida) from soil around the rhizosphere of bamboo from Manipur

Two new species of Mononchida, Actus conoidus n.sp. and Cobbonchus subcaudatus n.sp. are described and illustrated. Actus conoidus n.sp. was characterized by having L=1.21–1.39mm; a = 31.1–36.2; b = 4.1–4.5; c = 20.4–23.8; V = 59.0–61.7; c’ = 2.4–2.6; buccal cavity = 20.8–22.4x9.6–11.2 m, and more number of sub ventral teeth. Cobbonchus subcaudatus n.sp. had L = 1.00–1.23mm; a = 36.3–48.0; b = 2.8–3.3; c = 38.3–48.0; V=65.5–73.8; c’ = 1.2–1.3 in females; and L= 1.21–1.37mm; a = 40.0–47.8; b = 3.18–3.6; c = 36.2–43.0; T = 45.2–46.9; c’ = 1.31–1.33 in males. C. subcaudatus n.sp. was distinct in having longer buccal cavity, higher position of dorsal tooth, longer tail and more number of supplements.
