Forum Entomologi Italiani

Questo campione è stato raccolto, nel caso in cui qualcuno potesse identificarlo mediante osservazione al microscopio. Era nei pascoli di alta montagna.

Not easy to determination from only photo. Looks like members of T. monticola group.

Thanks Lech. It's very difficult to find enough info online. The monticola group is the same than subgenus Timarchostoma? According to Fauna Europaea, the next species of the subgenus can be found in Spanish mainland:
Timarcha affinis ----- > subspecies of interstitialis or of goettingensis?? endemic of Albères mountains, too far east for my specimen
Timarcha aragonica ------> subspecies of goettingensis? endemic to Albarracin in Teruel
Timarcha asturiensis------> red femora, endemic of NW Iberian Peninsula
Timarcha catalaunensis -----> subspecies of interstitialis, endemic to Gerona
Timarcha chloropus --------> endemic of Galicia and Portugal
Timarcha cyanescens-------> endemic to northern Spain it don't reach Pyrenees
Timarcha daillei --------> endemic to Pyrenees from Catalonia to Navarra, so it could be!
Timarcha geniculata----------> red femora, don't reach Pyrenees
Timarcha globipennis----------> endemic to Portugal?
Timarcha gougeleti------------> red femora, endemic to NW Spain
Timarcha interstitialis----------> apparently reach only eastern Pyrenees but not central Pyrenees (found in Catalonia but not in Aragon) where the location of this specimen is
Timarcha monserratensis------->subspecies of interstitialis? endemic to Catalonian mountains
Timarcha monticola------------> found in mountains of Aragon and Catalonia but not in Pyrenees
Timarcha oblongula------------> no data about location inside Spain?
Timarcha obsoleta-------------> endemic to western Pyrenees. It could be?
Timarcha perezi---------------> I know well this one, is the one found where I live. A lowland species, it could never be found at these high altitudes
Timarcha pontavicei------------> I can't find any info, probably a synonym?
Timarcha recticollis---------> endemic to central Pyrenees. I hope is not this one, as I already had this species
Timarcha sphaeroptera -----------> a southwestern species
Timarcha strangulata-------------> endemic to central Pyrenees over 1500 meters, so it could be!
Timarcha temperei----------------> endemic to central Pyrenees, so it could be!


So we have as very probable candidates:
Timarcha daillei, T. obsoleta, T. strangulata, T. temperei
And as vaguely possible candidates:
Timarcha oblongula, T. pontavicei

Any more help to find which ones can match with the specimen in the photo?
