At this moment 4 species of Macronychia subgenus Macronychia (having spine shaped piercer) are known in Europe: striginervis, dolini, substriginervis and lemariei (revisions by Verves, 2006 and Verves et al, 2009). M. kanoi is now considered to be a east palaearctic species.

However Verves does not describe the typical features of the Macronychia that is most common in North Western Europe. He uses features that are variable within this North Western species or not existent in the specimens of Macronychia in my collection.

Therefore it is wise not to speculate on the species-level until at least types of striginervis and ungulans have been checked.
