Chloeia egena Grube, 1855 Indeterminable

Chloeia egena Grube, 1855: 23–24; de Quatrefages 1866: 391–392; Hartman 1959: 131.

Remarks. Chloeia egena Grube, 1855 was proposed with a poorly preserved specimen deposited in Saint-Petersburg, Russia. The specific name, egena, means deprived of, missing, poor. The name might be derived of the lack of dorsal pigmentation of the type specimen, as indicated in the description (Grube 1855: 91), or because of the lack of denticulation of notochaetae (Grube 1855: 92). However, this smoothness was just apparent because all notochaetae were broken. This would probably explain why Horst (1910: 172) regarded C. egena as indeterminable, or that Benham (1916: 392) concluded that “it would be better to drop this latter name entirely” and Augener (1924: 259) shared this perspective. Because the type locality is unknown, there is no means to solve this, and the species name must be regarded as indeterminable.
