Abstract

Redescription of Rotylenchulus nicotiana (YOKOO et TANAKA, 1954) n. comb. was given. Adult female: shape of anterior part irregular and of posterior swollen, esophageal glands overlapped ventrally, two ovaries coiled or zigzaged, vulva elevated, distal part of tail slender, cuticle annulated, no lateral lines. Young female: slender, open “C” shaped when killed with gentle heat, cuticle annules fine, four lateral lines, esophageal glands overlapped ventrally, rectum clear, hyaline portion of tail 8.5μ long, stylet 18.8μ, o=81.3, vulva not elevated, V=69.2. Second-stage larva: shape similar to young female in outline but larger, esophageal glands small and overlapped ventrally, cuticle annules fine, tail without hyaline portion, stylet 16.5μ, o=95.3. Egg: elongate-oval, positioned as a mass within a thin gelatinous matrix around adult female body. Male: unknown. Neotype (adult female): L=698.3μ, a=5.5, b=6.4, V=58, swollen part 497.4μ long, stylet 16.2μ. Considerable variations in the shape of adult female, particularly of the anterior part, were observed presumably associated with the development of root tissue where the nematode had been located, of great burdock Actium Lappa L., a principal host of the nematode species. Nicotiana tabacum L. in which field YOKOO and TANAKA obtained their original specimens was found not to be fully suitable as a host for the parasite. Tomato Lycopersicon esculentum MILL. and sweet potato Ipomoea Batatas LAM. were also proved to be good host plants. Type locality: Wakimoto, Akune, Kagoshima (The name has been changed after YOKOO and TANAKA made their description).
