| Bonjour, Quelqu'un connaitrait-il le nom de ce carabique ? Trouvé au lac du Rorota (pas loin de Cayenne) en août 1994 Taille=12 mm | |

| Hi Carabus:
I believe that it is a Galerita sp. in this genus there is several species in South America. If I am not mistaken this species it is very interesting, because the species of Galerita that I know, don't have spots in the elytrons, this way this it is very pretty!!. Although it is strange that it has the extreme elitrals with tips. Tomorrow I will study the key for the genera of South America of Carabidae and I will inform you that I discover. I believe that this information is already something,
Meanwhile we wait the opinion of other entomologists. Now you will have to discover that species is it.
Cordial greetings
Carlos | |

| Hi Carabus: You excuses, but it can also be a Ega sp. or Colliuris sp. Although the species that I know in these genera are very small, less than 1/2 cm of long !!. Tomorrow I will study the key. Cordially Carlos | |

| Regrettably today I could not go to the museum. I don't believe that it is Agra, because the species of this genera that I know it has the pronoto lengthened as in these pictures:
But these species are from Paraguay:
pictrue 1 (Agra sp.): https://servimg.com/view/11945640/1
Picture 2 (Agra sp.) https://servimg.com/view/11945640/2
Picture 3 (Agra sp) https://servimg.com/view/11945640/3
Picture 4 (Agra sp.) https://servimg.com/view/11945640/4
The species of Agra in general live in trees, on the other hand the Galerita spp., Ega spp. and Colliuris spp. walking in the floor or they are caught with light traps (the Agra hardly arrives to the light !!).
How did you collect this species?
Although it could be an Agra sp.?, this way when I check the key of Carabidae (in museum) I will inform you Greetings Carlos | |

| Comme tu le disais justement sur un autre forum Entomofou, il va falloir que tu effectues encore beaucoup de séjours en Guyane Nous sommes effectivement plus proche de Galerita ou genres voisins que des Agra. L'espèce sujet de ce post est fréquente, notamment au Rorota, sur les feuilles de grand Balisier ( Heliconia sp) à vue de jour. Je n'ai jamais pris d' Agra (important genre très diversifié en Guyane) ainsi dont les représentants, contrairement à ce qu'indique Carlos, viennent fort bien au piège lumineux | |

Hi Carlos, thanks for informations. I think that this insect was on a leaf but not sure, it was 14 years ago ! I hope that you will find the species name. gmg a écrit - Citation :

De mémoire, il me semble que c'est arrivé comme ça mais c'est loin... | |

| Dear friend: As the picture it is not very useful to be able to see the characters that are in the key, I sends you this, so that you same can studies it with the specimen in your hands. I believe that first we have to see if it belongs to some of these genera, if it doesn't belong to none of them, then I will compare your picture with the different genera that we have identified in the collection of the museum to see that it can be. When we are more sure of the tribe then we will know to that genera belongs and we will attempt the determination until species, for the time being for my it continues being something very near to Galerita, the problem is that Carabidae has many similar genus.
Is interesting the comment of gmg, because apparently in each country it is different (but I don't know !!) since here the Galerita always come to the light and very rarely the Agra, can it also be for the deforestation? or is it that the Agra is stricter with the ecological requirements?. Cordial greetings

| Carlos, using your key, i find Galerita. I measured again the specimen and the size is more exactly 14 mm. Now, if you could help me to find the species name, it would be perfect ! | |

| Hi:
The monograph of the Galeritini is in this paper:
Reichardt, H. 1967a A Monographic revision of the American Galeritini (Coleoptera: Carabidae). Arquivos de Zoología de Sao Paulo 15 (1- 2): 1 - 176.
Galerita is a cosmopolita genera.
Distribution in America: Southestern of United States, Mexico to North Argentina Neotropical region: 52 species Brasil: 24 species Oriental Región with 8 species Africa (Inlcuded Madagascar): 17 species
I believe that in Paraguay there are 6 or 7 species ?, but this is alone speculative !!.
My problem is that I don't have the revision of the genera and like you can see they are many species, I know alone those of Paraguay thanks to a reference collection. On the other hand, if you allow me? could I show the picture to some friend or to put it in other forums to see if somebody knows the species? Lament to not be able to help you more than that, Greetings Carlos | |

| Hi Carlos, Thank you for your help. I am already happy with the genus Galerita. Of course, you can use the picture as you want to try to find the species name. Greetings. | |

| Ah... J'ai bien fait de revenir ... Effectivement, la comparaison avec un calophaena par exemple sur http://www.carabidae.ru/foto/displayimage.php?album=41&pos=3 est plus convaincante ! Merci gmg ! | |
