Dear all, Second Tachinid question for tonight: Here is a small specimen I identified as a Phasia following Central europe key. From side of Loire (ending of the Layon river, for those who are interested in Diptera and vine  ), wet area.Several specimens, I also caught a female (and I have picture in vivo of her) I totally dont get the first point of the Phasia key, so I followed both. Ibelieve it could be P theodori as: -halteres are yellow -hairs on peristome are totally white -S7 of female appear similar to the figure given. My little doubt are from the wing of male: It has is centraly black tinged (not greatly visible on this picture I am afraid). And wing is mention to be unspotted. So I am wrong? I apologize for quality of pictures, specimen is really small!  clovis : France : Chalonnes-sur-Loire : 49290 : 10/10/2020 Altitude : 12 m - Taille : 6 mm Réf. : 279635  clovis : France : Chalonnes-sur-Loire : 49290 : 10/10/2020 Altitude : 12 m - Taille : 6 mm Réf. : 279636  clovis : France : Chalonnes-sur-Loire : 49290 : 10/10/2020 Altitude : 12 m - Taille : 6 mm Réf. : 279638 |

As you noticed, wing colouration is off, moreover, it is too big. Are you sure it is Phasia and not Ectophasia ? When Phasia, obesa is the first species to check. Female genitalia are highly distinctive in Phasia. Theo Edited by Zeegers on 17-04-2021 15:57 |

Your right, this is Phasia obesa... In the mean time I caught a P pusilla: I now understand the "hairs on parafacial" critera! many thanks for putting me in right direction! |
