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.
