Hello, Found in deep south of France, in a small village. How can we make the difference between both of this genus ? Is this possible to do it, just with these photos ? I have other views if necessary.  MOLINIER Cédric : France : Llauro : 66300 : 03/07/2026 Altitude : 317 m - Taille : 10 mm environ Réf. : 375620 |

One often visible characteristic is the length (Lt) of the fore tarsus compared to the height of head (Hh): Dinera: Lt > Hh Billaea: Lt <= Hh This should be a Billaea, and I think it's Billaea maritima. I'm quite sure but if available, a caudal view could help to be safe. Greetings, Eric |
