Hello, Pierre Duhem : France : Paris : 75016 : 20/04/2017 Altitude : 42 m - Taille : 12-15 mm Réf. : 181177 Pierre Duhem : France : Paris : 75016 : 20/04/2017 Altitude : 42 m - Taille : 12-15 mm Réf. : 181178 I'm rather clueless for this specimen, pictured a few days ago in the bois de Boulogne (Paris). Can somebody give me a direction? Thanks in advance. Pierre Duhem |

Thanks, Jan. On the other hand, somebody told me that this should be a Sciophilinae, with the little square cell. pierred attached the following image: [35.45Kb] Edited by pierred on 23-04-2017 08:01 Pierre Duhem |

Yes, but this is Grzegorzekia. Sciophilinae have macrotrichia on wing membrane and usually unspotted wings. |

The r-r crossvein means Sciophilinae in the traditional classification by Edwards. Most of Edwards' subfamilies are now considered families. The family Mycetophilidae is restricted to (Mycetophilinae + Sciophilnae sensu Edwards) and is often divided into about 8 subfamilies. At least 2 of the new subfamilies have the r-r crossvein. I have also seen the crossvein called R2 and R4. |

The R4 cross vein is a widely distributed plesiomorphic character state across the subfamillies Mycomyiinae, Gnoristinae and Sciophilinae in the modern strict sense. But it is not present in all genera in any of these subfamilies. |
