Well.... I've never seen it, but I don't think it is cisalpinum. Did you compare it with Chrysotoxum festivum? Greetings and thanks for your mail about F. fumipennis! Edited by Andre on 24-08-2009 21:27 |

Thanks André yes , I have compared: festivum (male) has black frons, side border of the abdomen yellow and black, antennae: 1°, 2° and 3° segment of equal length. Faunaitalia signale from Sardinia (not surely reliable) only: intermedium, fasciolatum, bicinctum and cisalpinum I am not surer than the 3° segment =1° + 2°. Ciao Pietro |

I have been checking again and must agree with your ID, even before your reply. Been away though for a few days. Anyway, it convinced me that this is cisalpinum! Hope to find it too some day, a wonderfully nice species  Hope you will add it for the gallery? |
