I have seen this species from Borneo, but have not had a name for it.
Gerard, have you seen the type? Are you just comparing with a picture from Breuning, 1954?
The original description by Jordan does fit, however the description is very short. |

Breuning, 1954, Taf. XIII, Abb. 7: Pseudoschoenionta libellula
This is Breuning's (1954) picture Dan mentioned.
I have coloured it according to author's description. |

Francesco / Gerard,
Thank you for your efforts. I have been receiving some cerambycids from Crocker Range, in Sabah, since 1998, and the variety of Oberea and related genera is amazing. I have numerous species which are very, very similar. I have no way to prove that your identification of Pseudoschoenionta libellua is incorrect, and there is no way to prove that it is correct. I have one other similar "Oberea" like this photograph posted by Konstantin, except it has an extremely elongated abdomen (like Breuning's drawing)
At this time I have almost 40 distinct species of Oberea and closely related genera from the Crocker Range. I have only one of them positively identified because I prefer to rely on comparisons with holotypes for species in this complex group. Even recently, I obtained images of some types from the British Museum and could not be sure if they matched any of my specimens or not!!
I know it is frustrating when a species can not be identified, or when someone (like me) doesn't agree with you. I honestly believe that there may be as many as 500 - 1000 undescribed cerambycids in Borneo. But it is common for some species to occur in Sumatra, West Malaysia, Java and Borneo. |
