Greetings,
Looks to me to be a female of a species of Derobrachus, maybe asperatus? I've seen the female of the similarly rugose D. apterus, but the antennal segments in yours look different. I'll dig out the revision by Santos-Silva tonight and see if I can nail the det down for you.
Cheers!

Greetings,
I ran your specimen through the key in "Santos-Silva, Antonio. 2007. Revisao do Genero Derobrachus Audinet-Serville, 1832 (Coleoptera, Cerambycidae, Prioninae), Arquivos de Zoologia, Vol. 38(1):1-94" and it is indeed a female of Derobrachus asperatus Bates. It keys cleanly, and your specimen is from the known distribution which is primarily Costa Rica's western side, and into southern Nicaragua and northern Panama.
Nice bug!
Cheers!

Greetings,
This one is more difficult to ID 100% without the specimen in hand, but I think it is likely that it is Mallodon spinibarbis, as you suggest. The anterior angles of the pronotum project much further forward and the mandibles are somewhat more elongate than in typical M. dasytomus - the other common species in that area.
Cheers!

Greetings,
Glad to help! Robert - I sent you a P.M., but ignore it - I confused who had what beetles!
Cheers!

Hello To identify the American Mallodon in the past I recurred to this post, in the webpage cerambycoidea.com: Mallodon Those indications are the best thing I have found to determine the always confusing genus Mallodon. Regards |

Greetings,
Thanks Borja - that link will be very helpful! I had received this information years ago from Frank Hovore, now deceased - he stated the same concerns then (1996?) that no good literature existed to clearly separate the species in the spinibarbus/molarius/dasytomus/baiulus group. Antonio Santos-Silva is making good progress on sorting out some of the Neotropical prionine groups, but I don't believe he has dealt with Mallodon yet. For now, your link will be the 'go-to' source for me...
Thanks!
Bandrow
