Very nice. A female of the Tabanus glaucopis - group. In Czech, you have only glaucopis itself, I guess. So that is what is should be. The black on the subcallus seems a little bit restricted, though. Did you collect it ? Theo |

We have only T. glaucopis from glacopis-group in the Czech Republic. The other member of this group, T. exclusus, was extremely rarely collected in southern Slovakia. Theo: many of CZE and SVK glaucopis I have seen have similarly restricted black on the subcallus. Libor |

This pattern reminds of Tabanus castellanus, that is why I hesitated. But castellanus is not to be expected in Czech republic. So I guess glaucopis it is. Theo |

Is T. exclusus definitely excluded (!)- glaucopis group, subcallus only half polished? Chvala (1972) uses this feature to key out the group. |

SD, yes I know, however, excluses is indeed excluded, since this species has only a tiny bit (10-20%) shining black on the subcallus. THeo |
