Hi, I wondered if anyone could help with a Platypalpus I collected last summer? It's probably something common but I can't get it to key and the genitalia don't match anything that fits with the external features. I'll upload some pictures and they are also here: https://photos.app.goo.gl/n9cjQgMi4WMHh7D56 Given the photos aren't great I also noted the following: Basal antennal segments dark, segment 3 c.2* as long as wide, arista c. 2* as long as segment 3. 1 pair vt bristles, face and frons heavily silver dusted, Thorax lightly dusted/sub-shining above (rubbed?), acr bi-serial, large bristles brownish Legs mostly dark apart from some parts of tibiae (most of front) and metatarsi. Mid femora with long sharp spur and pv bristles present. Abdomen shining Collection data: Swept, wet limestone woodland, 20.06.2020, Siccaridge Wood, SO936032, UK Thanks for any help, Sam Sam Thomas attached the following image:  [22.91Kb] Edited by Sam Thomas on 26-02-2021 12:05 |

Are you using Adrian Plant's key? It seems to be P. albifacies. The left periandrial lamella matches that species. |

Thanks, description seems like a good match. I was using the DF workshop hadout/Plant key and had come to this as a possibility but can't find an illustration of the genitalia in the DF hadout, Collin or Fauna Ent. Scand. |

The genitalia are illustrated in Dipterists Digest Volume 13, Part 1 on page 34. That issue is available to download online. |
