Might be Eutrichota affinis section based on the missing prealar. In Manual of Nearctic Diptera Eutrichota keys out as Pegomya. The Anthomyiidae chapter was written before generic revisions by Hennig, Griffiths, and Michelsen changed most of the names. Is the scutellum yellow underneath and at the tip? |

I hoped that the wonderful costal spines give me directly the species name... Thank you, John. Nikita Vikhrev - Zool Museum of Moscow University |

Nikita Vikhrev wrote: I hoped that the wonderful costal spines give me directly the species name... Thank you, John. Griffiths (1984:491) writes "The members of the Eutrichota spinosissima superspecies may be distinguished from other members of the E. affinis section by the presence of long spines along the costa and by reduced eye size at least in the females. Both features are probably adaptations to a partly subterranean existence in the underground burrow systems of pocket gophers (Geomyzidae)." |

I thank John for his help and for fragment of Griffith's key to Eutrichota he sent me. According to this key it is E. geomyis Griffith, 1984, which means "pocket gophers Eutrichota". The male on photo was collected exactly in the type locality of E. geomyis (CollegeStation). Nikita Vikhrev - Zool Museum of Moscow University |
