Sarabeev and Balbuena (2003) considered Dicrogaster perpusilla and D. contracta (Digenea: Haploporidae) synonymous. They designated a neotype for the type-species, D. perpusilla, from a sample of specimens ex Chelon labrosus off West Thurrock, UK. The morphology of the material studied by these authors was re-examined in detail and compared with their data. The material labelled D. perpusilla from which the neotype specimen was selected, consists of 14 specimens; of these one might belong to Haploporus, one to Haplosplanchnus, and the remaining specimens may belong to Saccocoelium but the state of the material does not permit its reliable identification. The designated neotype of D. perpusilla is a neogravid dorso-laterally mounted specimen and is unrecognisable. The overall conclusion of the study is that the synonymy of D. contracta and D. perpusilla proposed by Sarabeev and Balbuena (2003) is based on questionable material.
