Abstract
Two species of the genus Pungentus originally described by Thorne and Swanger (1936), namely P. intertextus and P. tex-tilis, are re-described on studying type material. Both species are very similar morphologically and characterized by having large general size (body 3.7-5.1 mm long), odontostyle comparatively long (about twice the lip region width) and slender, with small aperture, relatively short neck (6-ratio = 7.0-9.0), rounded conoid tail, and slightly irregularly spaced ventromedian supplements which lack hiatus. This morphological pattern significantly differs from that found in other Pungentus species, and hence a new genus Stenodorylaimus is proposed to accommodate the two species herein studied. Descriptions, measurements, line illustrations and LM pictures are provided for both species. The new genus is compared in detail with its closest relatives.
