Hello :hi: , I have this Meloe specimen, it was collected on 7 December 2024 in a deciduous forest in Romania, the specimen being active during the night.

It could be Meloe (Eurymeloe) rugosus or maybe mediterraneus? What are the differences between these 2 species? From what I know they look very much alike :roll:

:hi: :hi:

In my opinion, it seems more overlapping to M. rugosus by the aspect of pro and mesosoma;
- antennae slenderer and longer than mediterraneus;
- head less wide, frontal sulcus uniformely deep up to frontoclypeal suture;
- pronotum clearly restricted back, well angled forward, with deep and narrow median sulcus; points, in anterior part at least, apparently rugose.
Genitalia also appear to be similar, but actually very similar to mediterraneus too.
Wait for others more reliable opinions. :hi:

I agree that it is M. (Eurymeloe) rugosus; it differs from mediterraneus because of its pronotum less transverse, more pentagonal and with a middle furrow; moreover the integuments are shiner.
The rugosus comex includes two very similar species in Italy, I descibed (digiuliorum, apenninicus, and two new undescribed species in Turkey.
Marco
