That's a tricky male! According to the key in
https://www.resea...hagionidae luteolus males have yellow tergites with at most a narrow dark band at the front edge. In the other two species of the
luteolus group (
nubecula and
laetus) the tergites are said to have broad darker transverse bands. In your male, the posterior half of the abdomen is dark, the anterior half light. If we decide on "dark transverse bands", we are stuck, however, because now the shape and size of the clypeus is species-decisive. And you don't have a close-up of the face. So possibly
laetus or
nubecula or, less probable, a miscoloured
luteolus (?)... Maybe Theo has an idea!
