These specimens are both from Borneo / Sabah (20/23 mm) If the right one is probably X. laticornis, I don't know if the left one could be striata or asphyxa ?.. X. striata is unknown on Titan base !!
C'est parce qu'il faut chercher Xoanodera (Lajoyeia) striata Gressitt & Rondon, 1970. Plusieurs Xoanodera se ressemblent excessivement; je m'étais interrogé ici et là .
Merci Xavier, j'ai effectivement trouvé ces différents posts sur le sujet. Au vu du comparatif ci-dessous: (G:laticornis/Borneo - C:striata/Thailand - D:asphyxa/Borneo), j'en arrive à la conclusion que l'espèce à gauche de mon post d'origine est X. asphyxa Franz,1972.
The one on the left in the original post is X. subdita Holzschuh, 2005.
X. asphyxa Franz, 1972 is usually 30-35 mm in size, and is not similar to this species. I am sure there have been images posted of X. asphyxa on the forum before.
Your specimen of X. subdita appears to have had a little pubescence rubbed off the pronotum
Thank you Dan and Andre. I can finish my labelling of this genus. Effectively i just found in coll. the species below (37mm from Borneo) corresponding to the type of asphyxa (was previously labelled as striata).
