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.
