Sphex erythrinus is also known from Kenya. GUIGLIA (1939: 201) attributes the authorship of the new taxon to P. Magretti (15.12.1854 – 30.08.1913), who has recognized the new variety ( MAGRETTI 1906). After the «marked description» of the new taxon ( GUIGLIA (1939: 201) she added the note: (Magretti i.L.) – see also the description of the new Platyderes Invreai n.sp. by Guiglia herself, which is not marked ( GUIGLIA 1939: 195). Solving the problem of authorship it is necessary to search for an unpublished manuscript of P. Magretti with the mentioned description in the museums in Genova and Milano ( Italy). The correct date of publication of the paper "Imenotteri aculeati raccolti in Eritrea e in Etiopia dal Ten. Colon. Dr. Giorgio Invrea" by D. Guiglia is 05.07.1939.
