I think this is the male of Helina. Candidates are evecta and latitarsis, but I do not really know how to separate them. I managed to shoot only this sole picture. Is the distance between eyes a possible character? Or is it variable within these species?

Hi Gabor, the darkened crossveins and the pattern of the abdomen point to H. evecta.

Thanks, but as far as I know these features are also present on latitarsis. What is exactly different?

From Mike Hackston (2019). Adapted from d’Assis Fonseca (1968):
"Body entirely black in ground colour. Thorax very thinly dusted, with hardly discernible markings. Eyes densely long hairs, separated by about the width of the 3rd antennal segment. Wings conspicuously infuscated on the anterior half..."
