ABSTRACT: When the genera Septatrocholina BouDagher-Fadel and Banner and Alzonorbitopsella BouDagher-Fadel were erected (BouDagher-Fadel 2008, pp. 161; 175), the genotypes Septatrocholina banneri and Alzonorbitopsella arabia, respectively, were described and figured, but through an oversight the holotypes and paratypes were not identified among the illustrated specimens. The type specimens are here subsequently designated, in accordance with ICZN 1999, article 69, and are further described. The type specimen slides are deposited in the invertebrate collections of the Natural History Museum, London.
