I have a feeling that your Agapanthini belongs either to the genus Trichohyllisia or to the genus Eohyllisia and maybe its alboineata species? What do you think? If it seems correct to you I'm looking in that direction. However stupid it may sound, look also at Hippopsicon victoria ssp transvaaliensis ? Though it's a long shot!
Okay great! The character of the lower lobes of the eyes is not always valid and sometimes questionable. If it is valid in some groups and even between some species in some genera African Agapanthini are particularly complicated to study and the characters are questionable
