Why not a Cnodacophora? |

To Sundew: What is the main difference between the two ? Thank you, D. |

Well, I wished I knew more about Micropezids, they are fascinating flies! I just know the key by Kahis (http://www.elisan...ropezidae/) that, however, does not include your fly. A difference between Neria and Cnodacophora seems to be details of wing venation, not recognizable in your photo, however. The Neria specimens I have seen yet look a bit different (just by jizz!), and when I searched for pictures of Cnodacophora, still unknown to me, in our gallery, I found a quite similar one (http://www.dipter...pid=204394). Therefore my question to the experts: why not Cnodacophora? I wish to learn, just like you! Regards, Sundew |

Many thanks Sundew, I will now immerse myself in the study of the subtle differences between the two genera :-) David |

The shape of the genital structure says it is Neria cibaria. One of the characters used to separate the genera is the way the subcosta en R1 meet the costa. In Neria they meet the costa very close together, in Composbata more widely separated.

So this would be the most light-coloured N. cibaria I have ever seen, especially concerning the occiput! And the genital is partly covered by the leg, so I cannot recognize the single posterior tooth of sternite 6 that characterizes the species (I add a photo of a N. cibaria male that I consider typical as to colour and genitalia). Dear Paul, you must have a very keen eye - how enviable! The different wing venation is pictured in the cited key by Kahis, but it concerns Cnodacophora versus Neria, whereas Compsobata is said to be a synonym of Neria... Anyhow, we cannot see it in Sezima's picture. Sundew attached the following image:  [143.63Kb] Edited by Sundew on 03-06-2013 14:04 |
