Surprise, surprise: I had the luck to see the actual specimens today and, lo and behold, it is NOT Atlestus pulicarius! It is the smaller brother, Atelestus dissonans. In an earlier vial I examined I had a male and a female of Atelestus, the male almost twice the size of the female. The male fitted the characters of A. pulicarius to the letter (with several stonger ad setae on the mid tibiae, the female fitted the characters of A. dissonans to the letter (frons virtually completely glossy black). If anyone might be doubtfull that the two species would be present on the same locality, the next vial (from the same site) had several males that fitted A. dissonans to the letter (smaller, no stronger ad setae on the mid tibiae). So, please, add another species to the Greek list. :D
