Cerviconema cygneum and Papuadorus amplus, two new genera and species (Nematoda: Dorylaimida) from high altitude regions

Abstract

Two new species of dorylaimid nematodes each representing a new genus are described and illustrated. Cerviconema gen. n., with C. cygneum sp. n. from Bolivia as type, belongs to the family Paraxonchiidae and is characterized by the strongly tapered neck, small head, simple and medium-long odontostyle, short cylindrus, paired gonads, transverse vulva and conoid tail. Papuadorus gen. n., with P. amplus sp. n. from Papua New Guinea as type, belongs to the family Nordiidae and can be characterized by the long and slender odontostyle, rod-like odontophore, amphidelphic genital organ, longitudinal vulva, great number of contiguous supplements and conoid tail.
