Odynerus antisrabensis Giordani Soika 1941

Odynerus antisrabensis Giordani Soika, 1941 nomen dubium Odynerus antisrabensis Giordani Soika, 1941: 175, ♀ —“Antisrabé” (type lost). Notes. As reported by Dal Pos et al. (2022: 9) the type specimens of several Malagasy Eumeninae described by Giordani Soika are lost, including the female holotype of Odynerus antisrabensis. Following the key and the description it is evident that O. antisrabensis is in fact close to Odynerus hyalinelamellatus and O. parvilamellatus, from which it would differ for the total absence of the apical lamella on T 2. Specimens potentially compatible with O. antisrabensis have been examined and resulted substantially identical to the holotype of Giordania nigra, suggesting that the latter could be a junior synonym of O. antisrabensis. However, these specimens still show some differences with what Giordani Soika reported in the brief original description (Giordani Soika 1941: 175), such as the color of the wings (pale ferruginous in O. antisrabensis, basally blackened and apically whitish in the available material), and the absence of a type does not allow clarification of the exact identity of O. antisrabensis, which belongs to a group of species whose females are very homogeneous. For these reasons Odynerus antisrabensis is here designated nomen dubium, thus giving priority to Giordania nigra (which is here considered as incertae sedis), the holotype of which allows ascertaining of the exact identity of the species and maintain taxonomic stability.
