    Three new species of Dorylaimoididae Siddiqi, 1969 are described and illustrated. Dorylaimoides chamoliensis n. sp. differs from the closely related D. teres and D. indicus in having wider body, longer spicules and short and differently shaped tail. Dorylaimoides kalingus n. sp. differs from the closely related D. pretoriensis in having smaller and narrower body, longer oesophagus, smaller spicules and longer and differently shaped tail, from D. arcuatus in having a set of basal oesophageal bulb, posterior vulva and smaller tail. Calolaimus amphidius n. sp. differs from the closely related C. lenorus and C. notus in having shorter body, thick-walled amphids and in the size of tail. A key to species of Calolaimus has been provided.

    Opisthodorylaimus n. gen., and some new and known species of Dorylaimoidea (Nematoda) from India
    (1982) Wasim Ahmad; Shamim Jairajpuri, M.
    A new genus Opisthodorylaimus closely related to Thornenema Andrassy, 1959 and Mesodorylaimus Andrassy, 1959 is proposed, along with the description of three new species, viz., O. maqsoodi n. sp. (type), O. caudatus n. sp., and O. chamoliensis n. sp. It differs from Thornenema in having an unsclerotized lip region and a broad odontostyle, while from Mesodorylaimus it differs in having an opisthomonodelphic reproductive system as well as a broad odontostyle. Jairajpuria oryzae n. sp. differs from J. shamimi Baqri & Jana, 1980 in the shape of lip region, posteriorly situated vulva, unsclerotized vagina and in the absence of a sphincter at the oviduct-uterus junction. Dorylaimus siddiqii n. sp. is close to D. thornei Andrassy, 1969, but differs in having a shorter and narrower body, differently shaped lip region, smaller and narrower odontostyle and in the absence of vulval papillae. Calodorylaimus indicus n. sp. differs from C. octo Andrassy, 1969 in having a smaller body, shorter odontostyle, longer oesophagus, posterior vulva and smaller spicules and tail. The male of Thornenema cavalcantii is redescribed. Laimydorus pseu-dostagnalis and Afrodorylaimus geniculatus are reported for the first time from India.

    Three new species of nematodes from sugarcane fields in Nigeria
    (1982) Shamim Jairajpuri, M.
    Three new species of plant nematodes belonging to the genus Boleodorus Thome, 1941 ; Paratylenchus Micoletzky, 1922 and Xiphinema Cobb, 1913 are described from the sugarcane fields in Gengola state, North East, Nigeria. Boleodorus acurvus n.sp. is closely related to B. clavicaudatus Thome, 1941 but differs in length of body and spear and in shape of lip region. The shifting of B. clavicaudatus to Boleodoroides Mathur el al., 1966 is disputed. Paratylenchus variatus n.sp. differs from the closely related P. leptus Raski, 1975 in shape of lip region and in the size of spear, and from P. colbrani Raski, 1975 in having only two or three incisures in the lateral fields, in shape of tail and absence of males. Xiphinema brevistylus n.sp. differs from the closely related X. tarjani Luc, 1975 in absence of "blind canal" in tail, smaller odontostyle and odontophore and anteriorly located vulva, and from X. vulgare Tarjan, 1964 in smaller and differently shaped tail, smaller odontostyle and odontophore and posteriorly located vulva.
