Lost or loaned materials The following species, recorded from the RMCA by the cited species authorities, are believed to be lost as they were no longer in the collections at the time of our study. The type specimens of two other species supposedly curated at the RMCA were also absent from the collections. These are: Coelioxys ateneata Strand, 1920 and Coelioxys neavei Vachal, 1910 . Of the supposedly lost material, the RMCA mentions a 1991 loan from Maximilian Schwarz for the genus Coelioxys , which has still not been returned. We resume these omissions below in order to complete the list of Megachilidae taxa curated at RMCA .
