This one looks way too similar to Heteralonia rivularis  (many times placed in genus Exoprosopa too). Going through the keys, just in case, it still takes me directly to that species. It is present in Greece but I cannot find if it is present in Rhodes  However it is a common and well distributed species. I wouldn't be surprised it is present in Rhodes anyway |

Thank you very much! First I also thought about Heteralonia rivularis, but finally I could not convince myself  Greetings from Hungary, Henrik |

I think now that this is also a female of Exoprosopa dispar. Heteralonis rivularis seems to have much more extensively infuscated wings, especially along some veins, e. g. m-m. What do you think? Thanks for any comment in advance! Henrik Edited by piros on 06-10-2016 13:53 |

Henrik, you are totally right. When I saw the first picture and the name in the title I said you myself 'It cannot be!!!' And certainly it is NOT Heteralonia rivularis (I must have seen this without glasses to see a H. rivularis in this one and key it as such). And now that we know the real Exoprosopa dispar  all makes a lot more sense!! What it is not surprising is that I keyed it to Heteralonia!! Remember that I told you before that E. dispar looked to be much closer to H. rivularis than E. minos!! For comparison, a real female Heteralonia rivularis, frequent in my area: Piluca_Alvarez attached the following image:  [182.11Kb] Edited by Piluca_Alvarez on 06-10-2016 19:40 |

Dear Piluca, I cannot thank you enough for your continuous interest and help with these Bombyliidae! Of course, I remember your note about the similarity between E. dispar and H. rivularis, and the dissimiliraty between the former and E. minos! With the help of your exceptionally neat picture of H. rivularis, one can also see that this sp has light brown patches of hairs on the side of anterior tergites, which are lacking in E. dispar. Actually, I am very glad that we cleared this confusing situation Greetings, Henrik Edited by piros on 06-10-2016 20:58 |

I would also appreciate if someone could give me the reason for H. rivularis being considered a member of the genus Hetralonia and not Exoprosopa! |

Dear Henrik, there is nothing to thank. You were the one that found and photographed and IDed the male and the female of the real E. dispar There was a 'before and after' that moment About the taxonomic position of these two species there is no consensus as far as I know. In the old times they were placed in Hyperalonia in the subgenus Cladodisca (and separately from the true Exoprosopa). In the World Catalog for Bombyliids (1999) they appear as Heteralonia (genus with various subgenera) but in unplaced subgenera. In Fauna Europaea they both appear within Exoprosopa. And in Systema Dipterorum (I think it was updated sometime after 2010) they appear as Heteralonia again but under the subgenus Zygodipla. My opinion doesn't count as I am an amateur and certainly I cannot be more away from being a taxonomist But for me, these 2 are too different from the real Exoprosopa. Exoprosopa s.st. (capucina, pandora, cleomene, jacchus, italica, bowdeni...) are all extremely related and share many characters in common. All the other species with the 'adicional vein' seem to be related but in a separate 'branch'. I am absolutely unaware of genitalia similarities within the groups or what DNA studies might be revealing. But to my amateur feeling the old classification had more sense: Exoprosopa s. str. and Exoprosopa s. lato (Hyperalonia, with several subgenera and dispar/rivularis within Cladodisca). Nothing seems to be like that anymore and I am sure there is a strong reason for that, of which I am totally unaware Loads of babbling for saying nothing, really Sorry, but this is all I can help you with  |
