Hello, I created a post on the forum Le Monde des Insectes with this Haematopota identified as italica. With the Chvàla, I have a little doubt now. Because of the first antennal segment quite brown (blackish-grey in italica) and abdomen brown too. Could it be an other species (pandazisi for exemple) ? In alcohol :  Benoît Lecaplain : France : Lassy : 35580 : 30/07/2018 Altitude : NR - Taille : 11 mm Réf. : 344689  Benoît Lecaplain : France : Lassy : 35580 : 30/07/2018 Altitude : NR - Taille : 11 mm Réf. : 344690  Benoît Lecaplain : France : Lassy : 35580 : 30/07/2018 Altitude : NR - Taille : 11 mm Réf. : 344686 In collection :  Benoît Lecaplain : France : Lassy : 35580 : 30/07/2018 Altitude : NR - Taille : 11 mm Réf. : 344687  Benoît Lecaplain : France : Lassy : 35580 : 30/07/2018 Altitude : NR - Taille : 11 mm Réf. : 344688 We have a little constriction (clearly visible) on first antennal segment. Femora light brown. In a moor. Thanks for your help, Benoît Edited by BLecaplain on 11-09-2024 12:27 |

Comparaison between italica (left) and this Haematopota. First antennal segment is more brown. But this tabanid was in alcohol since 4 years. Maybe coloration is not a good criteria ? Edited by BLecaplain on 11-09-2024 12:55 |

pandazisi = rotundata ? Maybe a strict southern repartition ? Mentionned by Séguy in 1926 in north western France (named variegata) https://academic.oup.com/jme/article-abstract/7/5/543/2222086?redirectedFrom=fulltext "The result of the last mentioned record is that the common South European species of Haematopota known as variegata F. must be named pandazisi Krob., 1936." |

As you mention, alkohol tends to revive the colouration. Grey will not turn easily red, but slightly red might turn very red .... beware of this. Secondly, italica is very variable in colouration. Your statement that first antennal segment is not red in italica is generally but not necessary always true. Finally, when I look at these pics, it seems to me that there is an indication of a sublateral spot on second tergite. If so, this would confirm my gut feeling, namely that this is the female of H. grandis. Theo |
