Adams & A. Adams, 1855 Ennea H. Adams & A. Adams, 1855: 171 . Ennea — Zilch, 1960: 577 . Ennea — Richardson, 1988: 19 . Ennea — Schileyko, 2000: 798 . Type species. Pupa elegantula L. Pfeiffer, 1847 ( Fig. 20 ), by subsequent designation ( Martens, 1860: 302 ). Remarks. Ennea is characterised by deeply situated long parietal plicae, which are absent in the genus Sinoennea . Although the southern Indian Rowsonia , new genus , has similar plicae, the close relationship between African Ennea and Rowsonia is unlikely due to biogeographical reasons (see also under Rowsonia , new genus ).
