GENUS PUNGENTUS THORNE AND SWANGER, 1936

Syn: Pungentoides Altherr, 1950 Paramonovia Eliava, 1973. ( Fig. 61 )

Diagnosis: Small- to medium-sized nematodes (0.6-3.8 mm). Lip region usually set-off from body; lips angular and labial papillae raised. Four cuticularised platelets surround entrance to stoma. Amphids usually with stirrup-shaped fovea and slit-like aperture. Odontostyle small to long, with distinct dorsal aperture, rarely slightly concave dorsally. Guiding ring ' double' Odontophore rod-like. Junction of odontophore and oesophageal lumen surrounded by conspicuous muscles. Basal expanded part of oesophagus occupying less than one-half oesophageal length. Cardia hemispherical or elongate, cardiac disc may be present. Vulva transverse. Female reproductive system mono-opisthodelphic, rarely amphidelphic. Males with arcuate spicules, lateral guiding pieces and series of spaced ventromedian supplements. Tail short, hemispherical, rarely clavate or elongate-conoid; similar in sexes.
