Thank you very much, Lech!
I probably have other 5 species in a differente genus very close to this one.
I'll take picture when possible (sorry for the bad preparation, but I think they were killed in ethanol 90%).

My PhD student Joanna Pomorska is just working on a revision of African Cryptonychini thus the group is well known to us.
Here is link to the recent world catalogue of Hispinae by C.L. Staines with many colour photos, including the Gyllenhaleus bipunctatus: http://entomology.si.edu/collections_co ... pines.html

Thank you. Very interesting papers! Perhaps I found one of my species, but I am not sure.

It is a member of Curculionoidea not Chrysomeloidea, very strange. I never seen similar beetle but had collected in Ecuador some very mysterious curculionids of similar shape. Please send the photo to Marek Wanat (wanatm@biol.uni.wroc.pl). He has a good experience in many exotic groups of Curculionoidea.
