Bradford-Grieve J.M., (2002 onwards). Key to calanoid copepod families. Version 1 : 2 oct 2002. http://www.crustacea.net/crustace/calanoida/index.htm  | | Rem.: | Wilson places this new family in the superfamily of the Centropagina (Gurney, 1931). Furthermore, this superfamily would comprise the family of the Pseudocyclopidae but not the Platycopiidae for which the systematic position cannot be defined in spite of Lang's opinion (1948). Fosshagen adds the genera Exumella and Placocalanus permitting him to redefine the family of the Ridgewayiidae. The author underlines that certain characters can be interpreted either in a phylogenetic sense or as adaptive convergences to quasi benthic life conditions. In this sense Placocalanus shares characters with the Harpacticoidae. Concerning this family, Andronov discusses the hypothesis of Gurney on the filiation of the Calanoida and places the Ridgewayiidae in the superfamily of the Pseudocyclopoidea (with the Pseudocyclopidae) closer to the ancestral forms than all other families. For
Boxshall & Halsey (2004) this family is included in the superfamily of the Epacteriscoidea).

The small, compressed and slender body-shape, the short, modified A1, and the unusual P1 seem to indicate this way of life. The function of the large process on A1 is not obvious, but it may be related to the bottom-living habits of the species; it may act as a shield protecting the mouthparts when the animal forces its way through loose sediment, or as a device for stirring up particles and for digging. It is to notice characters in common with several harpacticoids, such as the large single aesthetasc in the middle of A1, the modified P1, and the outer setae on the coxa of P1, P3 and P4. The structure of P1 suggests that this limb has other than a purely swimming function, perhaps being used for digging or holding fast to the substrate. | | Remarks on dimensions and sex ratio: | | The mean female size is 0,486 mm (n= 4; S= 0,061; Cv= 0,126) and the mean male size is 0,455 mm (n= 5; S= 0,058; Cv= 0,127).
