| Abstract: | The trematode,Alloglossidium anomophagis sp. n. (Digenea: Plagiorchiidae) exhibits progenesis in water fleas of the genusDaphnia (Anomopoda: Daphniidae) occurring in temporary rainwater-filled ditches near Houston, Texas, USA. We assume thatA. anomophagis has achieved its truncated life cycle by eliminating the vertebrate which originally served as the definitive host. The adults ofA. anomophagis represent the smallest trematodes in the family Plagiorchiidae, measuring less than 0.5 mm in length. |
