Contributions to the genus Opisthodorylaimus Ahmad & Jairajpuri, 1982 (Nematoda: Dorylaimida), with descriptions of two new species

Abstract

Two new species of the genus Opisthodorylaimus are described. O. mitis sp. n. from Guadeloupe and Ecuador is characterized by a transverse vulva, very long egg, lack of an anterior uterine sac, and by a filiform tail. O. papuanus sp. n. from Papua New Guinea is distinguished by a longitudinal vulva, lack of a prevulval uterine branch, and by a long, filiform tail. Two known species of the genus are also presented: O. cavalcantii (Lordello, 1955) from Vietnam and O. maqsoodi Ahmad & Jairajpuri, 1982 from Seychelles. The taxonomic position of Opisthodorylaimus is commented, and the distribution of its ten species outlined. A key to species is added.
