fg-taxon #55 (unknown dexiine)
This is a nice little brightly-marked taxon with bright orange abdominal side patches, contrasting with a dark black body colour; shaded wings; small orange antenna with a plumose arista; and quite a deep gena. Unfortunately my only specimen is not in the best of condition.
EDIT (Monty Wood 26/9/2010): This is an unknown genus in the dexiinae – it doesn’t conform to any of the known genera.
