I comment you I was collecting insects in a Eucalyptus crop and I found a specimen that I could determinate until subfamily Cerambycinae.
I do not have keys.
I would like to know if you can help me with the identification in order to know if the insect is about a xylophagous beetle, related to Eucalyptus trees.
I attach more Photos to your e-mail.
I appreciate your big help. Thank you.
Best regards,

Listroptera tenebricosa differs from L. carbonaria in the shorter and broader elytra, with strongly adsperate epipleurae (lateral margins), prominent dorsal costae, coarse deep and seriate punctuation; the clubs of the metafemurs are relatively enlarged.
I cannot observe the last character, but for example, the adsperate epipleurae are well visible.
You can compare both species here.
Concerning the generic characters inside of the tribe, it is more complicate since I have to resume a long paper... a bit of patience. |

Hello Oscar Dix, welcome to the Forum!
Your insect is Listroptera tenebricosa (Olivier, 1790), Rhopalophorini.
According to Napp & Mermudes (2001 - Revision of the genus Listroptera Audinet-Serville and description of Aguassay new genus (Coleoptera, Cerambycidae, Cleomenini) - The Coleopterists Bullettin 55/1: 1-9) its larvae attack Acacia farnesiana and Zanthoxylum rhoifolium.
I ignore whether Eucalyptus has been subsequently signalised as host. |
