Remarks: The type species of the genus, T. antarctica Lubbock, 1876, considerably differs from the Nordic forms listed below as the members of the genus following Dunger & Schlitt (2011) who mixed a number of unrelated Nearctic and Palaearctic forms under the name “Nordic group of Tullbergia sensu Fjellberg (1998) ”. This group does not appear to be natural and needs revision.
