Ebenia sp. ??? (French Guiana)

Ebenia sp. ??? (French Guiana)
Recently I have found quite a few small, black tachinids with a very plumose arista. Some are entirely black and others are a little dusted but they all have the anterior katepisternal bristle directly ventral to the pleural suture, which is a very unusual feature and suggests to me that if they aren’t Ebenia (a ...

Atactosturmia/Leschenaultia/Lespesia sp. ??? (Bolivia)

Atactosturmia/Leschenaultia/Lespesia sp. ??? (Bolivia)
This specimen is proving to be a real problem – it keys to Atactosturmia because it has 3 rows of small hairs outside the vibrissa and a bristle-comb on the hind tibia (amongst other things). But Monty things that it looks more like Leschenaultia or a black Lespesia, which only have 1 row of hairs outside ...

Drino sp. ??? (French Guiana)
Needs confirmation but the lack of occellar bristles is fairly indicative.

Thelairaporia sp. ??? (French Guiana)

Chaetona sp. (French Guiana)

Chaetona sp. (French Guiana)
This is an interesting tachinid with a hairy (not plumose) arista, shaded wing, strong subvibrissal bristles, bristled prosternum etc. It keys to Chaetona but this genus usually has a plumose arista … this one is definitely hairy but not what I should call “plumose”, as such. EDIT (17/10/2010): Confirmed by Monty Wood from these photographs.

fg-taxon #71
This is an interesting pair of specimens, both with short ‘tails’ and an ovipositor. Apologies for the poor quality of the photos but the specimens are very small and not suited to my simple camera set-up:

Daetaleus cf. purpureus (French Guiana & Peru)

Daetaleus cf. purpureus (French Guiana & Peru)
While examining what I thought was a Peruvian Mesembrinella (Calliphoridae, Mesembrinellinae) I realized that I was in fact looking at a tachinid – with a normal metathoracic spiracle and no pale hairs under the scutellum. Then when I examined my trap of Mesembrinella I found 2 more from French Guiana. They key out to Scotiptera (Dexinae) and ...

Stacking / compositing photographs
Recently a local photographer called Dave Dare got in touch with me to ask if I could lend him some specimens so that he could practice macro photo stacking/compositing. This seemed a great opportunity for me to help someone out and also have some of my favourite specimens photographed with very deep focus. Dave has ...

Argyrochaetona sp. (French Guiana)

Argyrochaetona sp. (French Guiana)
This little Carcelia-like tachinid stood out from the rest of the Carcelia and Houghia spp. because the dusting was very different and the humeral callus had bristles arranged in a line. I have made a slightly tentative identification of Argyrochaetona sp. because it runs very well to this genus in Monty’s key (even up to ...

Neobrachelia sp. (Peru)

Neobrachelia sp. (Peru)
This is a Neobrachelia sp. – the colours have come out a little bit too green in the photos – the dusting is really yellowish-grey. Det: Monty Wood, 2010.

Pseudochaeta sp. (Peru)

Pseudochaeta sp. (Peru)
This is a specimen of Pseudochaeta – a Carcelia-type tachinid but with a row of strong facial-ridge bristles.

Homogenia sp. (Brazil)

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.

Sturmiodexia sp. (French Guiana)

Sturmiodexia sp. (French Guiana)
As the name suggests these are dexiines that look remarkably similar to relatives of Sturmia, such as Winthemia. However these are clearly not Winthemia because they have a very plumose arista. Det: Monty Wood, 2010.

Siphosturmia sp. (French Guiana)

Siphosturmia sp. (French Guiana)
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 ...

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.

Houghia sp. (French Guiana)

Houghia sp. (French Guiana)
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.
