Remarks: The majority of the above Nearctic records probably belong to T. sibirica ( Christiansen & Bellinger 1998; see also remarks to T. sibirica ). Potapov (2001) also wrote “having large amounts at material from the Arctic, we did not find this species [true arctica ] anywhere but from Ellesmere Land”. On the other hand, “the taxon sibirica as defined by Potapov (2001) … is not sharply set off from arctica Cassagnau, 1959 ” ( Fjellberg 2015, p. 64). It is therefore still an open question which of the species ( T. sibirica , T. arctica , or both) occur in the northern Nearctic.

General distribution: uncertain.
