Pseudosiphona sp. (French Guiana)

Pseudosiphona sp. (French Guiana)
The Pseudosiphona look superficially like a Siphona but with a much shorter labrum. You should also be able to just make out the strong ventral bristle on the katepisternum. Det: Monty Wood, 2010.

Pseudochaeta sp. (French Guiana)

Pseudochaeta sp. (French Guiana)
Pseudochaeta is another of the Carcelia-type tachinids, with large eyes, but it also lacks the tuft of hairs on the hind coxa, present on Carcelia. It also has a strong row of facial-ridge bristles. EDIT (09/10/2010): I have found a second specimen virtually identical to this one from Peru. Det: Monty Wood, 2010.

What a difference a day makes ...
Here I just wanted to show you how Chrysoexorista spp. loose their colour almost over night. This first photos show how the Chrysoexorista looked a few hours after it had been removed from the malaise trap alcohol and the last 3 show how it looks now:

Ceromya sp. (French Guiana)

Ceromya sp. (French Guiana)
As you might expect, the siphonines are well represented in the neotropics and familiar genera, like Siphona, Actia and Ceromya can be found. The group is quite easy to determine from the small size, hairy r4+5 (often also r1 and cu) and long, converging or parallel subapical scutellar bristles. Beyond that Monty’s key splits the ...

Carcelia sp. (x2) (French Guiana)

Carcelia sp. (x2) (French Guiana)
The genus Carcelia seems to be fairly ubiquitous around the world. The presence of the extremely deep eyes and very narrow strip of gena (the eye is at least 11x bigger than the gena) and the presence of a tuft of small hairs on the hind coxa is very distinctive. In the following photos the ...

One of the commonest phasiine genera – note the strong divergent lateral scutellars. Determination by Monty Wood.

Xanthophyto sp. (Bolivia)

Xanthophyto sp. (Bolivia)
This is quite a distinctive genus – with the shaded rm. It belongs to the tribe Nemoraeini. Determination initially by me – confirmed by Monty Wood.

Winthemia sp. (French Guiana)

Winthemia sp. (French Guiana)
Apparently Winthemia are pretty much the same the world over – 2 katepisternals with hairy parafacials. Determination by Monty Wood.

Zelia sp. (French Guiana & Costa Rica)

Zelia sp. (French Guiana & Costa Rica)
This is a huge genus containing many superficially dissimilar species. Determination by Monty Wood.

Uramya (French Guiana)

Uramya (French Guiana)
Uramya is one of the genera where the males have very long ‘tails’ … sadly this is a female! Determination by Monty Wood.
