Checklist
General remarks: The list includes only formally described species. Newly discovered, but still unnamed species are excluded. However, unnamed species or species unassigned to species level are included, if they are the only representatives of their genus in the region. Species counts exclude extinct and introduced species. Doubtful records, typically older voucher specimens of uncertain origin, have been excluded if considered questionable, as are records based on sources considered unreliable or controversial.
Note: Your comments to the checklist (omissions, errors, etc.) are welcomed, preferably if they are provided with reliable references. If possible, please attach a pdf file of the relevant reference to an email addressed to:
