July 21, 2006. A single specimen was collected by sweeping. Size 2.5 to 3mm. I think it's a different species than the two I posted earlier (if it's only a Piophilidae at all). Dmitry Gavryushin attached the following image: [104.38Kb] Edited by Dmitry Gavryushin on 23-07-2006 13:55 |

I think that stripped eyes lead us rather to Sciomyzidae. It seems that everything OK for Pteromicra oldenbergi, Sciomyzidae. The main problem - it is RARE species, so let's wait for expert, but please meanwhile be carefull with collected fly in case that I'm right. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I believe it is Pteromica glabricula. Very close to oldenbergi, but the latter species has no orange on frons (glabricula has narrowly orange anterior margin). The 1st picture shows some yellow near the base of the 3rd antennal segment even if it is not well visible. Kahis |

Hi Kahis. But in Stakelberg key P. oldenbergi - striped eyes (on alive fly), 1 or; P. glabricula - 2or, eyes without strip. I think there is only 1 or? Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I guess Stackelberg uses the name glabricula for the species now known as angustipennis. This misuse was corrected only in 1970. The real glabricula is probably P. nigrimana or P. albitarsis (or missing alltogether) in your key. P. glabricula is a species with only one orbital seta on each side. I don't know if it has banded eyes when alive. Edited by Kahis on 23-07-2006 19:50 Kahis |

Thank you Kahis. Nikita. P.S. According Stakelberg banded eyes - oldenbergi and nigrimana. Nikita Vikhrev - Zool Museum of Moscow University |

It seems that this species is rather common in appropriate habitats. Yesterday I've collected 20+ specimens by sweeping at Ozhigovo station (ca. 55km SW of Moscow). It was a very wet deciduous forest (Alnus/Ulmus/P. tremula) near a swamp, with thick and diverse herbaceous vegetation (including Carex, Phragmites, high broad-leaved grasses, Lysimachia, Solanum dulcamara, Oenanthe, Delphinium, Impatiens, Galium, Veronica, Scutellaria galericulata, Lycopus, etc.). There was also a lot of dead trees, both standing and fallen on the ground.

Now all completely according with Rozkosny and Kahis - antennae 3-d vetro-basaly yellow - Pteromica glabricula.

I collected three more specimens on August 03, 2006 in our town park, not far from water again, so it's another proof for my previous remark on this species occurence in my neighbourhood. |
