It's a male Phania and as the abdomen is dusted: Phania speculifrons, I think (a very rare one!).
Greetings, Eric |

My gut feeling says Labigaster. Since we cant see the bridge behind hind coxae, we need to think about this. Theo |

Hello Theo thank you for the Answer. But Leucostoma sp. can't be right if you look at the wing. In Phania species, the veins converge to a point at the wingtip, as you can see in my photo. In Leucostoma species, the veins do not run together, but there is a right-angled cross vein. Kind regards Karl. Edited by karl7 on 14-12-2025 11:19 |

Leucostoma ? I said Labigaster Secondly, the calypter is enlarged, a clear sign of Leucostomini. As is the silvery face. Thirdly, in male Phania speculifrons, the vertex is 0,75 -0,8 x width of an eye. In your pic, it is much smaller .... In Phania, the bend of median vein is much closer to wing margin. In both Phania and Labigaster discal bristles are lacking In Dionaea, they can be present. And there seem to be some small hairs on parafacial.... So my current hypothesis is Dionaea, next of kin to Labigaster. Definitely not Phania for the reasons given above. Theo |
