Afropectinariella (Vandeae, Orchidaceae), a new genus of the Angraecum alliance

A recent phylogenetic study showed that species assigned to the newly recognised genus Pectinariella Szlach., Mytnik & Grochocka (previously treated as AngraecumBorysect.Pectinaria Benth.) are polyphyletic, comprising a clade with species primarily in Madagascar and the Western Indian Ocean islands (including the type) and another non-sister clade whose members occur in continental Africa and the Gulf of Guinea islands. In order to render Pectinariella monophyletic, the five continental African species must therefore be removed. A new genus, Afropectinariella M.Simo & Stévart, is described and the following combinations are made: Afropectinariellaatlantica (Stévart & Droissart) M.Simo & Stévart, Afropectinarielladoratophylla (Summerh.) M.Simo & Stévart, Afropectinariellagabonensis (Summerh.) M.Simo & Stévart, Afropectinariellapungens (Schltr.) M.Simo & Stévart and Afropectinariellasubulata (Lindl.) M.Simo & Stévart.
