Paraspidodera uncinata is a parasitic in the cecum and colon of guinea pigs living nematode of the family of Heterakidae . It belongs to the so-called awl tail . It causes heteracidosis in rodents .
morphology
Adult forms of Paraspidodera uncinata are 1.1 to 2.5 cm long. The mouth opening is surrounded by three lips, delimited by constrictions, on which two dorsal and one subventral papilla sit. The esophagus has a marked end bulge (end bulb). The cuticle is striated across and bears small lateral wings.
In males, the rear end is pointed and caudal wings are not formed. There is a suction cup and numerous papillae in front of the cloaca. In the cloaca, males have two evertable, approximately equal-sized auxiliary mating organs ( spicula ). The female's vulva lies behind the midsection.
