Checked: verified by a taxonomic editorType material ''The type specimen of the type species was not deposited in Sweden, although it was collected during a Swedish expediton, nor in Hamburg, where Augener lived. Museum curators were unable to find it, therefore the type and only specimen is being regarded as lost.'' (Salazar-Vallejo et al., 2007: 539). [details]
