Leptomenes laethificus Giordani Soika, 1941 View in CoL nomen dubium

Leptomenes laethificus Giordani Soika, 1941: 187 View in CoL , ♂ —“ Madagascar: Maevatanana ” ( 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 holotype of Leptomenes laethificus View in CoL . The identity of this species is doubtful as the description does not allow it to be associated with any of the seven species of Malagasy Leptomenes View in CoL identified in this revision, as it presents evident morphological (e.g., clypeus, propodeum, T1, apical margin of T2) or pattern differences with all of them. It is noteworthy that Giordani Soika (1941: 188) reports in a footnote that the specimen presents some transverse striae and grooves on the metasoma, interpreted as developmental errors of the specimen which could indicate that the specimen was anomalous in other aspects as well. In addition, Giordani Soika (1977: 115) himself later reports that the attribution of the species to the genus Leptomenes View in CoL is doubtful due to the strongly convex shape of T1, but the comparison of the description with all the Eumeninae studied during this revision did not allow identification of some correspondence with any of them. Given the absence of a type specimen and the impossibility of associating this taxon with any of the known species of Malagasy Eumeninae , Leptomenes laethificus View in CoL is here considered a nomen dubium.
