I guess this Tacinid will be a challenge. Found in forest area, Southern Norway, 7 July.

I think it is not Phorocera, as it has postpronotal setae in a distinct triangle. Plesae check for the hairs on the vein R4+5, if there are hairs to the midway of the R-M crossvein, than it could be Belida angelicae. Erikas |

According to the Central European key Belida has bare eyes and a broader frons (at least 0.71 as wide as an eye). As a member of tribe Blondeliini it should not have a right-angled bend in vein M. |

Thank you very much John and Erikas! I think the third antennal segment is too small to be Phorocera obscura... Morten |

In the tribe Exoristini postpronotal setae are not arranged in a distinct triangle, therefore I excluded them.

You may include just three characters in the interactive key of Cerretti for Exoristinae (1. eye pubescent, 2. postpronotal setae in a triangle and 3. depression on basal syntergite extending on the proximal half) and you will get only three genera: Istocheta, Lecanipa and Ptesiomyia. The first two are Blondeliini with obtuse angle of medial vein, therefore the third one is the most suitable identificaion.

Ptesiomyia alacris, to be more precise.

but the first supra-alar is short, I’d say that is a no-go. Habitus is like Belida, costal spine is strong, eye look bare in one pic and hairy in the other, very confusing, apical scutellars are short, … I still think it is Belida. Vertex is not that broad …. Theo |

I also had doabts about Ptesiomyia, but Morten has ignored my first question about the bristles on the vein R4+5, so could you answer please? Hairs on the eyes seems rather short to be treated as clearly pubescent.
