Two species of the genus Pungentus, one new and one known, collected in natural vegetation and cultivated soils in northwest of Iran, are studied. Pungentus sufiyanensis n. sp. is characterized by its 1.22 to 1.57 mm long body, offset lip region by a constriction and 7 to 9 μm broad, 18 to 21 μm long odontostyle, 304 to 348 μm long neck, 133 to 161 μm long esophageal expansion, mono-opisthodelphic female genital system without anterior uterine sac, slightly backward directed vagina, absence of pars refringens vaginae, V = 47−54, rounded-conoid caudal region (17.5–23 μm, c = 65–84, c´ = 0.7–1) with saccate bodies, and the absence of male. Molecular analysis, based on D2-D3 expansion segments of the 28S rDNA (LSU), confirms the monophyly of the family Nordiidae and suggests the monophyly of the genus Pungentus, with the new species forming a clade with other Iranian species. New data are presented for six Iranian populations of P. engadinensis, and an updated key for the identification of Pungentus species is also provided.
