Genus Pomponema Cobb, 1917

Diagnosis (emended after Tchesunov, 2014). Body cuticle heterogeneous with fine punctations, and with or without lateral differentiation of longitudinal rows of enlarged dots commencing some distance behind the head and occasionally with slit like markings. Cuticle in head region may be thick with punctations appearing in lateral view as elongated rods with Y-shaped ends. Anterior sensilla consist of two circles, 6 + (6 + 4). Inner labial sensilla setiform. Outer labial and cephalic sensilla setiform and usually jointed in same circle with tip section markedly narrower than base, although this may be difficult to discern in some species; (6 + 4) arrangement of cephalic setae, six larger than four, but the four smaller setae sometimes absent or at least so small and adherent to the six larger setae that they cannot be detected. Amphideal fovea multispiral. Buccal cavity armed with a large pointed dorsal tooth, medium-sized subventral teeth, and with or without additional minute denticles. Pharyngeal bulb absent. Males with two opposed testes, rarely only one. Females didelphic-amphidelphic. Precloacal supplements consisting of several elements best seen in ventral view. Gubernaculum with variously structured distal ends, sometimes with L-shaped lateral plates or lateral flanges bearing blunt teeth. Tail conico-cylindrical with a swollen tip.
