Probably Amara convexior, check if the lateral points are continuous batch, or if they have a large break in the middle |

hi alexandru it would prove useful also to check: 1) position of pore at posterior angles of pronotum: + or - at the vertex of the angle, or distinctly more away from lateral edge than from posterior one) 2) scutellar pore of elytra (at base of scutellar striola) present or absent |

Caro Maurizio ritengo superfluo partire da zero tutte le volte, conoscendo un pò le Amara, soprattutto quelle piu comuni, si nota chiaramente che qui si tratta di Amara communis o A. convexior, per cui basta controllare i punti marginali, se sono disgiunti si tratta di communis se invece sono continui di convexior this is clearly Amara communis or A. convexior, so just check points marginalized, if they are disjoint communis but if there continues to convexior |

probably this is correct, yet i believe it's preferable, when giving a determination, to explain the diagnostic features within the group and to check them; after all, many friends here are not specialists, even more of such a large and difficult genus as Amara, therefore some explanations may eventually lead non-specialists to learn something more  ...

This specimen has the lateral points continuous batch.... |

Ok, this probably confirms what was already suggested above: Amara convexior |
