hi alexandru

you should re-prepare the specimen, with spread wings, examination of wing venation of both fore and hind wings is necessary even for genus determination

Siobla sp. but the black color (aberration or variety ?) of Antennae does not allow me to determine the species.

Thank you for your answer :birra: :hi: , but what about Ametastegia equiseti, it can't be this species? :roll:

:ok:

from the first pictures, this clearly appeared to be a Selandriinae (sensu berland, faune de france), not a Tenthredininae, thus not Siobla ;)

3 submarginal cells in fore wing = not Allantus

i asked for a picture showing the hind wing, since i was in doubt between Taxonus (2 closed medial cells *) and Ametastegia (no closed medial cells)

* following the now obsolete berland's nomenclature :oops: yet i still have to learn the recent correct one :oooner:
