Taxonomic note
The name Caenia has been used in multiple taxonomic groups. Robineau-Desvoidy (1830) used Caenia for a genus of Diptera (Ephydridae), which is now considered a synonym of Coenia. The genus Caenia Newman, 1838 is valid and distinct. Care must be taken to distinguish these homonymous usages in literature searches.
Species inventory
Only three are formally described: Caenia amplicornis LeConte, 1881; Caenia dimidiata (Fabricius, 1801); and an undescribed species referenced as 'sp-nova'. The actual may be underestimated given limited taxonomic study.
