hi flyforum, This afternoon I found 3 Dexiosoma's. From what I know, it could be Dexiosoma caninum again.. The arista is quite short and plumosa as well. Am I right? place: Amsterdam forest date: 8-08-2010 greeting Robert Robert Heemskerk attached the following image:  [151.31Kb] Edited by Robert Heemskerk on 08-08-2010 18:50 Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

Yes  There is no central facial ridge and the bend in the median vein has a long appendix

Thank you Chris, central facial ridge; are these the inter frontal bristles? (standing upwards)? Robert Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

No - in some dexiines (eg. Dinera & Dexia) there is a rounded ridge between the bases of the antennae, reaching down towards the mouth edge - usually big enough to be visible in side profile
