Not exactly sure about this one I would appreciate any help. Not sure about the country either, data reads: "DPTO Concepcion zanja merroti Octubre 2008" Attachments:

Ctenoscelis coeus, male. It occurs in Brazil, French Guyana, Bolivia.

Thanks, I wasn't 100% sure I thought it looked a little different from the typical coeus.

No, the one that's pictured here is a male, the one on the website is a female of Ctenoscelis coeus. I have a nice series of both species. Jeff Prill

Yes,Jeff, this is definitely a male of coeus. albatus,this website has mistakes -it has even 2 males of coeus pictured on the acanthopus' page -check better the pictured specimens..

I noticed more mistakes on the above Cerambycidae site, for example they have one photographed pair of Stenodontes damicornis (Puerto Rico,Jamaica) identified as Callipogon barbiflavum (Cuba,Bahamas). plant.cdfa.ca.gov/byciddb/details.asp?id=260

Hi mate,
You are right, these can't be S. damicornis, as Stenodontes don't have hair on pronotum, elytra and mandibles and damicornis has also an extra tooth close to the edge of mandibles (however, the color can't be a point, as Stenodontes vary from dark to light brown). BUT : if you except the hair, all the rest characteristics are of Stenodontes...(shape of pronotum, of mandibles, short third antennomere*, etc), especially of that female, but also of the male. So I don't think that this species should have been put under the genus Callipogon. Actually these are the only specimens of this species that I have seen, and cause of the Stenodontes characteristics they have, I thought that they would be something similar to damicornis and that barbiflavum would be something similar to proletarium and sericeum from the same part of the world, both of which have all the characteristics of a Callipogon and are similar the one to the other. But if these photographed specimens on this site are indeed what Callipogon barbiflavum is, then I think the species needs revision and to be put under a new genus, or to keep the Dendroblaptus (Ok, maybe not to be put under Stenodontes cause of the hair, but they do have the characters of a Stenodontes including the thin mandibles of the male -the character based on which Stenodontes was named, the short third antennomeres, pronotum's shape, ..). (Btw, Dendroblaptus comes from the Greek 'dendro'=tree and 'blaptus'=the one that causes damage, meaning the one that damages the trees. So it has nothing to do with its morphological characteristics - instead of Stenodontes that means 'thin teeth' - but with its biology).
*in Callipogon the third antennomere is much longer than the fourth, while in Stenodontes these antennomeres are of about equal size.

Greetings, Since this is such a rare species and so few images are available, I wanted to image the pair in the collection here at the Carnegie Museum of Natural History to share with everyone. These were taken in Cuba, Isle of Pines, Nueva Gerona, 31 July 1912. I also donated these images to the Cerambycidae Catalog website to add to that gallery... Enjoy! Bandrow Attachments:

bandrow, thank you for the photos !!
All I can say is that the species is a mixture of Stenodontes and Callipogon, with more characteristics of Stenodontes, as I told above ,- for sure it needs revision !

I checked in literature that Lameere (1902) puts this species under Stenodontes as : Stenodontes barbiflavus, which is a synonym for the accepted scientific name today : Callipogon barbiflavum Chevrolat, 1864. I'm wondering how, with such morphological characteristics, it was put under the genus Callipogon .. For example, I'm not aware of any other Callipogonini which has of equal size the third and fourth antennomeres.....etc.. For me, Lameere was more wise than Chevrolat that put it under Stenodontes, however I think that, cause the species has mixed characteristics of both genera (with most of Stenodontes), it needs revision and to be put under a new genus (or the Dendroblaptus). It looks like a cross between Callipogon sericeum and Stenodontes cubensis, both of which occur in Cuba.

Greetings, I agree with your assessment, Thanos. Callipogon barbiflavum does appear more closely related to Stenodontes, than to Callipogon. One of the most obvious differences is the pubescence of the body, which is never present in Stenodontes, and which could be the character that has distracted earlier workers from the obvious relationship to Stenodontes, giving more weight to the presence of pubescence than is warranted. However, in the form of the mandibles and proportions of the antennal segments, it doesn't really fit Callipogon either. I would also agree that it likely deserves to be placed in its own genus, and the name Dendroblaptus would be the most appropriate generic name. The genus Callipogon probably needs further splitting - elevating all of the subgenera to generic level is likely justifed, as was the removal of Orthomegas . Sounds like a good paper for you to tackle Cheers! Bandrow

bandrow,
may be is too late, but can you contact me? I have wrote a book about the Cerambycidae from Cuba and I am very interested by that species. Thanks Sergio Devesa
