Acaulona or Xanthomelanopsis ??? (French Guiana & Surinam)

Acaulona or Xanthomelanopsis ??? (French Guiana & Surinam)
Acaulona & Xanthomelanopsis look very similar to Pennapoda spp. but without the leaf-like antero-dorsal bristles on the hind tibia. The only difficulty with these flies is that I just can’t make up my mind whether they have enough dorsocentrals to qualify as Xanthomelanopsis.

Homogenia sp. (Brazil)
These quite large (>1cm) phasiines are obviously in the tribe Trichopodini but they only have small leaf-shaped hairs on the hind tibiae. Det: Monty Wood, 2010.

Pennapoda & Xanthomelanodes sp. (French Guiana & Bolivia)

Pennapoda & Xanthomelanodes sp. (French Guiana & Bolivia)
Pennapoda & Xanthomelanodes are very commonly caught genera – being part of a group of very similar phasiine genera with shaded a costa and often with orange abdominal patches. Pennapoda closely related to the genus Trichopoda and both have leaf-like antero-dorsal bristles on the hind tibia, to a greater or lesser extent. Determination by Monty ...

Pennapoda sp. ??? (pe-taxon #30)

Pennapoda sp. ??? (pe-taxon #30)
This little phasiine is undoubtably a member of the Trichopodini, from the leaf-like bracts along the hind tibiae. This is very similar to some of the taxa from French Guiana – namely fg-taxon #8 #9 & #43. EDIT (04/10/2010): This keys quite comfortably to Homogenia sp. but it is much smaller than the other Homogenia ...
