Classification and/or Status |
|
Remarks | Differs from Acrosalenia in having a slightly stronger posterior elongation of the apical disc opening and a more slender and much more strongly U-shaped posterior genital plate. Haime established this genus on the specimen illustrated here. As Wright (1856) documented, this was very quickly treatred as a synonym of Acrosalenia. |
