This bug is so amazing those balls on his antennas and his colors are beautiful.
SukanyaDatta, Brian38, Mel11 and Saturniidae27, thank you.
Wow! I am always ...always totally blown away by the expertise PN commands. How wonderful to have a name...and such a learning experience for me. Thank you.
Ok, erase all that was said before. I got this message from my friend Jackson Brilhador, an expert in Cerambycidae: "@Sergio Monteiro, in fact, this specimen is not a variation and does not belong to the species Cosmisoma chalybeipenne (Rhopalophorini), because this species has tufts of hair inserted in the distal part of the V antenomers, and reach the elitral apex. It is also observed that they have pedunculated and strongly claved femurs, and surpass elytra. Also, I emphasize that this species is not cataloged in the state of Santa Catarina, only in São Paulo and Mato Grosso do Sul (Monné, 2020, p. 771).However, this specimen has the tufts inserted in the VI antenomers and the femurs are gradually claviform, therefore, it belongs to the genus Paromoeocerus sp. (Unxiini), another characteristic is the coloring of the head and the prothorax, which are black, so it is limited to only two species.These species are P. notabilis and P. scabricollis, however to distinguish them from one another it is necessary to analyze the last urosternites, which the photo does not provide the vision.However, considering the location (São Bento do Sul - SC), this would be a new record of the species for the state of Santa Catarina, because until then, no record is registered to your state.Sincerely, Jackson"
I agree now, probably a color variation. Thanks for the feedback
@Saturniidae27: Apparently there is some variation in the color of the torax within this species. I added an older photo, of a couple mating, where it is possible to see that. And it is not a gender differentiation, as you can see here: https://www.projectnoah.org/spottings/89.... I am pretty sure that this is not C. flavipes.
The main difference between Cosmisoma chalybeipenne, and Cosmisoma flavipes. Is that Cosmisoma flavipes has a dark blue-ish color, on the thorax like yours.While Cosmisoma chalybeipenne, has a bright orange on the thorax, and head.See these links for comparison:Cosmisoma chalybeipenne: https://www.whatsthatbug.com/2008/11/26/...Cosmisoma flavipes: http://bezbycids.com/byciddb/wdetails.as...
That's the best name they could give it "Long Horn beetle"? Great spotting Sergio!
