Hi ¡
I am not sure if this sp. is a Geotrupes, I have been comparing this sp with geotrupes from spain :

Geotrupes ibericus Baraud, 1958
Geotrupes mutator (Marsham, 1802)
Geotrupes puncticollis (Malinowsky, 1811)
Geotrupes stercorarius (Linnaeus, 1758)

but all of them have the elitra lines really visible. Another possibility is Jekelius or Thorectes.

Bests.

Hi,
take a picture also ventrally

It seems to me a A.stercoraris...sure not a G. mutator...but I don't know the other 2...

Hi ¡¡ here you an find the ventral photo

Now it is easy: Sericotrupes niger (Marsham, 1802).
By the way, Geotrupes puncticollis (Malinowsky, 1811) is a junior synonym of G. spiniger (Marsham, 1802).

The ventral photo helped a lot, I agree with Marco on the identification.

Thanks so much ¡

Whats the main difference between secicotrupes and geotrupes? because I find them really similar¡

Bests

Geotrupes: elytral striae very deeply impressed; elytral interstriae convex; upper surface more or less shiny.
Sericotrupes: elytral striae faintly impressed; elytral interstriae flat; upper surface not so shiny, almost silky.

Tnaks so much¡¡¡¡
