''Pseudoctomeris sulcatus'' is a species of barnacle, the only member of the genus ''Pseudoctomeris''. It has an eight-plated shell wall with the rostrum partially fused with adjacent rostrolatera. The suture lines are visible only from the inside, thus in exterior view, the shell appears to have six wall plates. The basis is calcareous. Opercular plates are higher than wide, and not deeply articulated. These features and others, show greater relationship to family ''Pachylasmatidae''. Taxonomic revision of Pachylasmatidae may warrant transfer of ''Pseudoctomeris'' to that family.〔 Diagnostic soft part characteristics, as described in Poltarukha, 2006〔 include a tridentate mandible and presence of a multi-jointed caudal appendage. As ''Pseudoctomeris'' is monotypic, the genus characters are necessarily the same as those of ''P. sulcatus''. == Nomenclature and Synonymy ==
