Description: BOdY STOUT WITH A BLUISH OR VIOLACEOUS SHEEN. PRONOTUM SUBqUAdRATE, ALMOST TWICE AS BROAd AS LONG. ELYTRA SHORT ANd STOUT, WITH SHALLOW ANd RATHER dISpERSE pUNCTURES. IT HAS SEVERAL LOCAL RACES, SIX Of WHICH ARE CONSIdEREd AS VALId SUBSpECIES, dISTRIBUTEd AT LOW ANd MEdIAN ALTITUdES fROM NAVARRA TO EASTERN ASTURIAS IN SpAIN, ANd ALSO IN THE PYRENEES ATLANTIqUES Of FRANCE ( BECHYNÉ 1953; GÓMEZ-ZURITA 2008).

THE ENdOpHALLI ( fIGS 21A, B, C, d ) Of THESE TAXA RESEMBLE TO THOSE Of THE pREVIOUS TWO SpECIES ALTHOUGH IN SOME pOpULATIONS THEY ARE NARROWER ANd MORE SLENdER, THEIR MANUBRIA CAN BE dIVIdEd OR SIMpLE, ANd THEIR fLAGELLI ARE THIN ANd WEAKLY OR MOdERATELY SCLEROTIZEd. WE HAVE TENTATIVELY CONSIdEREd IT AS A dISTINCT SpECIES BASEd ON THE EXTERNAL MORpHOLOGY BUT THE SHApE Of INTERNAL SACS ARE NOT CLEARLY dIffERENT fROM THOSE Of THE pREVIOUS TAXA, THEREfORE , ITS TAXONOMIC CATEGORY IS dOUBTfUL.
