Distribution

Palaearctic. Recorded from Austria and Switzerland ( Chandler 2004), southern Finland ( Jakovlev and Penttinen 2007), Murmansk Province ( Polevoi 2010) and East Russia ( Zaitzev 2003). New to the Republic of Karelia.

Ecology

The Karelian specimens were collected in mixed and aspen dominated deciduous forests. In Finland the species was reared from a decaying spruce log bearing polypore fungus Antrodia xantha ( Jakovlev and Penttinen 2007).

Notes

This species is closely related to widely distributed T. vulcani Dziedzicki and might be overlooked in other countries ( Jakovlev and Penttinen 2007).
