These are 2 Siphosturmia spp. The first looks very like a Winthemia but on closer examination is has 4 katepisternal bristles, not 2. EDIT (05/10/2010): I am a little suspicious about the second specimen – I think I might have written the wrong name down because the humeral callus has a triangle of bristles, and ...
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 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.
Here are a few more Carcelia-like tachinids but this time belonging to the genus Houghia, which lacks the tuft of hairs on the hind coxa: Det: Monty Wood, 2010.
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:
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 ...
This genus is related to the multi-fissicorn genera, like Cryptocladocera & Cerotachina (all members of the Neominthoini but most do not have multi-fissicorn antennae) . This species is distinguished by having a completely black T5. Determination by Monty Wood.
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 ...
