It's Calosoma madeare?
Location: Italy,Piacenza,12.5 2007
body length:30 mm-female

Aspettando la conferma dei big a me pare Calosoma (Campalita) maderae (Fabricius 1775)

Please, in English, thank you Milo

hi milo

... more exactly it's Calosoma (Campalita) maderae auropunctatum Herbst, 1784, in my opinion not a good species

you can find here a discussion about C. maderae-complex, should you have problems in understanding Italian, please feel free to ask for

Thank you very much,Maurizio....... so it's not ssp.maderae(Fabricius,1775),but ssp.auropunctatum?

yes milo, as you can see, the boundary between maderae s.str. and maderae auropunctatum in Italian peninsula is not clear-cut, and intermediate populations are known

in northern italy, animals from piedmont, lombardy and western emilia (e.g. piacenza), except for very occasional maderae here and there (most likely wanderers from liguria coastal area), are well characterized as auropunctatum, with elytra dull, coarsely scale-like sculptured, distinctly striate all over their length

conversely, animals from some populations in adriatic coastal area of emilia-romagna (e.g. ravenna) are often almost impossible to place with certainty; together with a small number of auropunctatum-type and maderae-type (elytra shining, with scales flattened, striae finer and backwards more or less obsolete), much more animals are found, where one or another status of each of the said features can occur at random, with no recognizable relation to each other

elytra: 1. Italy-female

hi milo

ok, i agree that central european and southeastern individual of auropunctatum are rather different, and i add that some northern animals i have seen are even more so, with even coarser elytral sculpturing and often ground color dark olive-greenish, instead of black

yet, since nobody seems to have treated southern animals as a separate (sub)species, i have to suppose that a gradual clinal variation occurs from czechia and slovakia, across hungary, former yugoslavia, to greece... and across slovenia and croatia, to italy; without a clear borderline between two different forms

of course this may well be wrong, yet to decide about, much more material from a number of european localities would be required, material i currently cannot have at hand
