<paragraph id="45F6FD268071857060F4D9CC1BBA16F5" pageNumber="355">The described members of this group are distributed in the Malagasy, Oriental, Malesian, East Palaearctic and Nearctic regions; the group has not yet been found in the Afrotropical, Austral or Neotropical regions, and is also absent from the West Palaearctic. The four species discussed below are known only from Madagascar; the group is discussed in more detail under the Malesian-Oriental-East Palaearctic fauna.</paragraph>
