Diagnosis:
Meteorus eklundi
can be distinguished from related species by the stout antenna with articles that are quadrate in shape.
M. eklundi
mostly resembles
M. nadezdhae
(East
Russia
) but the latter species has a rugose face, with the rugosity extending down onto the clypeus, and a strongly rugose petiolar tergum, whereas
M. eklundi
is only equipped with light sculpture in these body regions.
M. eklundi
also resembles
M. obfuscatus
but differs from this species by larger and more convergent eyes, narrower face (face wider than high in the latter) and shorter malar space (0.4 times basal width of mandible in the former, 0.5 times in the latter).

Biology
:
Meteorus eklundi
is caught in malaise traps during the summer months June, July and August. The
three specimens
that were caught within the SMTP were found in localities with deciduous forests. Host unknown.
Etymology:
Named after my best friend Mr Niclas Eklund.
