I present to you the three species described. Dan tu a Paratype of the beast described by C. HOLZSCHUH dedicated to you? I'd like to see if I do not have a new species. I have three other close beasts of Cyriopalus hefferni from different sources. Another question someone already did the Parameres of this kind? |

Gerard, thanks for the very good photos which you have posted.
I have some male and female paratypes of C. hefferni, all from Sabah.
I have seen only a couple of C. wallacei from Sabah over 14 years, so it is not common there. I have no females of C. wallacei (that I know of) from Sabah. I appear to be missing females of wallacei from other places, too.
The two species are hard to separate in my opinion. I look at the ratio of the length / width of the elytra. As you can see in your pictures, C. hefferni is more elongate. C. wallacei is usually larger (males). C. wallacei has thicker 3rd antennomere (males). The length of the spines at the apex of the elytra is sometimes a useful feature, but varies a little bit with each individual.
Almost all other Cerambycini from Sabah can be separated by their pronotal sculpture. But C. wallacei and hefferni have very similar sculpture.
Are there more undescribed species of Cyriopalus? Are yours from Laos or Borneo? Holzschuh has indicated to me that he thought there was another one in Sabah, but it was a female. My opinion is that there are many undescribed species of other Cerambycidae in Borneo. I only have material from Sabah, and it is just a small part of Borneo. My estimate is that there are possibly 1000 undescribed Cerambycidae in Borneo.
I am not sure if I have answered your question. Please ask if you have a question.
You should try to meet Holzschuh when he goes to Prague for the insect bourse, as he rarely communicates by email.

Thanks a lot Dan I am going to unite more animals, to be able to work on this genus which have a larger distribution . Can you say to me what the female of C. hefferni looks like? If you can make me a photograph, It interests me. Females are much less easy to find.![](images/icon_smile_wink.gif)

I don't have a photograph of the female. All my other photographs were taken by a friend.
Females are larger and do not have pectinate antennae. |

Ok, I found a photo of a female C. hefferni from my collection. It is a paratype.

Thank you very much, Dan. It confirms the appearance that I was female. ![](images/icon_smile_wink.gif) |
