Description of new and known species of the rare nematode genera Qudsiella Jairajpuri, 1967 and Swangeria Thorne, 1939 (Belondiridae: Dorylaimida).

摘要

Two new and a known species of the rare genera Qudsiella and Swangeria are described and illustrated. Qudsiella tropica sp. n. is characterised by having a 1.3-1.5 mm long body, a rounded lip region continuous with the body, 3 micro m long odontostyle with distinct lumen and aperture, vulva located at 40-42% from anterior end, long filiform tail, 26-30 micro m long spicules and three or four regularly spaced ventromedian supplements. Qudsiella gracilis is redescribed based on specimens collected from India, Japan and Nicaragua. Swangeria longicauda sp. n. is characterised by a 1.2-1.3 mm long body, truncate lip region continuous with the body, 2.5-3 micro m long attenuated odontostyle, expanded part of pharynx occupying ca 34-35% of total neck length and long filiform tail. The diagnosis of each genus is emended.Digital Object Identifier http://dx.doi.org/10.1163/138855410X494152
