fg-taxon #51 (Telothyria sp.) 2

fg-taxon #51 (Telothyria sp.)
A light brown tachinid with a slight similarity (in my eyes) to the sarcophagid subfamily Miltogramminae … and yes, it does have a strong subscutellum! 😉 EDIT (Monty Wood 26/9/2010): This is another Telothyria sp. – see also here. They all have branched hairs on the pleurae.

fg-taxon #26

fg-taxon #26
This is an elegant, slim tachinid – at first appearing very average but on closer inspection quite distinctive.

fg-taxon #24 (Cryptomeigenia sp.) 2

fg-taxon #24 (Cryptomeigenia sp.)
This taxon is a fairly common, brown and quite boring-looking “species” but it seems quite distinctive, nonetheless. I have found it in good numbers and the basic morphology seems to be quite stable. EDIT (Monty Wood 26/9/2010): These are all Cryptomeigenia sp. – a genus that often comes to light traps.

fg-taxon #13 (Myothyriopsis sp.)

fg-taxon #13 (Myothyriopsis sp.)
This is a really pretty little tachinid with shaded wings and well-dusted thorax. EDIT (Monty Wood 26/9/2010): This is a Myothyriopsis sp. – parasitoids of Heliconius butterflies.

fg-taxon #52 (Borgmeiermyia sp.)

fg-taxon #52 (Borgmeiermyia sp.)
This is the other half of a pair of very similar taxa (see also fg-taxon #53). This one has a much longer antennal segment 3 and less thoracic dusting. And here is a rather spectacular specimen, which is presumed to be the female of this taxon. Note the swollen fore basitarsus; large piercer and opposing ...

fg-taxon #53 (Borgmeiermyia sp.)

fg-taxon #53 (Borgmeiermyia sp.)
This is one of a pair of very similar taxa (the other is fg-taxon #52) – very small in size (3-5mm), with black body, orange legs and plain wings. This taxon has a shorter antennal segment 3 and a little more dusting. EDIT (Monty Wood 26/9/2010): This is a Borgmeiermyia sp. – but not one ...

fg-taxon #35 (Anisia sp.)

fg-taxon #35 (Anisia sp.)
This taxon has the dark wing area restricted to above r1 and a faint dark patch near the wing tip. EDIT (Monty Wood 26/9/2010): This is an Anisia sp.

fg-taxon #22 (Genea & Leskia sp.) 1

fg-taxon #22 (Genea & Leskia sp.)
This is a complex of basically orange-coloured tachinids with more or less darkened tips to the abdomen – either dark patches around the bristle sockets or completely dark tergite 4-5. This is taxon 22a – female (Genea sp.): This is 22a – male: The next one (taxon 22d specimen #73 – Leskia sp.) is much ...

fg-taxon #15 (Archytas & Jurinella sp.)

fg-taxon #15 (Archytas & Jurinella sp.)
This is another Tachina look-alike but with a projecting mouth edge, like Linnaemya. EDIT (Monty Wood 26/9/2010): This group contains 3 spp. of Archytas and 1 spp. of Jurinella. The photo shows one of the Archytas sp.:

fg-taxon #14 (Winthemia sp.) 1

fg-taxon #14 (Winthemia sp.)
This taxon group contains specimens that have a strong resemblance to members of the Sturmiini. All specimens have recumbent hairs and bristles with a tuft of stronger bristles on the most posterior tergites and the males all have a large, dense ‘Sturmia spot’ on the underside of the tergites. This is a female: This is ...

fg-taxon #12 (completely unknown)

fg-taxon #12 (completely unknown)
This is a really unusual small tachinid with mottled wings and unusual venation. EDIT (Monty Wood 26/9/2010): This is a really unusual fly and not one that Monty could place – even in a subfamily – so it remains unidentified.

Mesembrinella (Calliphoridae, Mesembrinellinae) & Dexiinae (fg-taxon #16)

Mesembrinella (Calliphoridae, Mesembrinellinae) & Dexiinae (fg-taxon #16)
This taxon group contains at least 7 species ranging in size, with a light brown ground colour, broad bodies and darker coloured abdomens. They have plumose antennae and quite a strong subscutellum but, after checking with the Manual of Central American Diptera (Brown et.al., 2009), it appears that most of them belong to the subfamily ...

fg-taxon #20 (Jurinia sp.) 1

fg-taxon #20 (Jurinia sp.)
This taxon is very similar to taxon #45 but larger in size. Note the very broad, shallow scutellum with distinctive row of scutellar bristles, combined with golden thoracic dusting and a shiny abdomen. They look superficially like Tachina spp. in Europe but they have a projecting mouth edge and quite a few other disimilarities. EDIT ...

Chrysotachina cf. braueri & ornata (fg-taxon #21)

Chrysotachina cf. braueri & ornata (fg-taxon #21)
The specimens in this taxon group are all metallic tachinids and almost certainly comprise at least 2 taxa. The first is relatively undusted and looks most like Chrysotachina braueri while the other, dusted taxon, looks most like Chrysotachina ornata but I am not convinced that the genitalia match closely enough to be the same species. ...

fg-taxon #45 (Jurinia sp.) 1

fg-taxon #45 (Jurinia sp.)
This really is a little beauty and very similar in morphology to taxon #20 (golden dusted thorax, shiny black/red abdomen & distinctive broad, shallow scutellum with a row of scutellar bristles), but this one is much smaller and has a black abdomen with a dark, central wing patch. There are 2 specimens in this taxon, ...

Borgmeiermyia brasiliana (fg-taxon #11, ‘feather-face’ #2) 3

Borgmeiermyia brasiliana (fg-taxon #11, 'feather-face' #2)
This is a male of the second taxon to exhibit the highly modified antenna-3, shaped like a feather. All specimens of this taxon are between 4-5mm long and so the photographs are of quite low resolution. However, you should be able to see: the distinctive black body with golden dusting pattern; completely orange legs; slightly shaded ...

Pelecotheca (Cryptocladocera) sp. male (fg-taxon #4) 3

Pelecotheca (Cryptocladocera) sp. male (fg-taxon #4)
This is one of my favourite French Guianan tachinids! At first glance it looks fairly standard but when you examine the face you will see that antennal segment 3 (normally rectangular) has been formed into a feather-like structure, similar in design to moth antennae! This structure is recessed in a deep concavity in the face ...

fg-taxon #3 (Zelia sp.)

fg-taxon #3 (Zelia sp.)
This is a more typical tachinid – a dexiine with plumose antennae and a conventionally proportioned body and colouration. EDIT (Monty Wood 26/9/2010): This is a group of Zelia sp. – a very large and diverse genus.

fg-taxon #8 (Xanthomelanodes & Pennapoda sp.) 1

fg-taxon #8 (Xanthomelanodes & Pennapoda sp.)
This “taxon” is actually probably 5 taxa but they share very similar superficial morphology – they are almost certainly phasiines and they have the typical chololate-coloured body with paler markings; a deeply shaded wing costa; and a large head with large eyes. Specimen #79 (8a) is shown here (Xanthomalanodes sp.): Specimen #351 (8b) is shown ...

Zelia sp. (fg-taxon #2)

Zelia sp. (fg-taxon #2)
This taxon looks very similar to taxon #1 but it is subtly different. It closely resembles a box of “Zelia sp. indet.” in the NHM, London:
