The first record of Brachycyrtinae (Hymenoptera, Ichneumonidae) in Finland

Background

Brachycyrtinae is a small, but distinctive subfamily of Darwin wasps (Hymenoptera, Ichneumonidae) with one widespead species in Europe: Brachycyrtus ornatus Kriechbaumer, 1880. We recently collected the species during the faunistic survey of the Urban Biodiversity Parks project in Skanssi, Turku, south-western Finland.

New information

We report the Darwin wasp Brachycyrtus ornatus as the first record of the subfamily for Finland. We collected a single female specimen with a Malaise trap in Skanssi Biodiversity Park during a period from August to September 2024. This is the northernmost record of B. ornatus and the subfamily Brachycyrtinae as a whole. Notes on the species' distribution and morphological variation are included.
