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?

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

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 :)
