title: Description of Proyseria petterae n. sp., with an amended generic diagnosis and a review of the species of Proyseria Petter, 1959 and Stegophorus Wehr, 1934 (Nematoda: Acuariidae).
abstract: Proyseria decora (Dujardin, 1845) (the type-species of the genus Proyseria Petter, 1959) is redescribed on the basis of specimens from Alcedo atthis (L.) (Coraciiformes: Alcedinidae) from Iran. P. petterae n. sp. is described from Corythornis vintsioides (Eydoux & Gervais) (Alcedinidae) from Madagascar by light and scanning electron microscopy. Proyseria sp. from Alcedo euryzona Temminck from continental Malaysia is described on the basis of a single male specimen. Stegophorus alcedonis Puqin, Yanyin & Guocal, 1991 from A. atthis in China is transferred to the genus Proyseria as P. alcedonis n. comb. The generic diagnosis of Proyseria is amended. Review of the species of the genera Proyseria and Stegophorus Wehr, 1934 is presented.
