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:

Scotiptera cf. venatoria (fg-taxon #7) 1

Scotiptera cf. venatoria (fg-taxon #7)
The fly was bought for a few francs from a butterfly collector in Cacao and it came without any data but with the assurance that it was collected locally. The specimen was badly greased and at first appeared black but after a bath in ethyl acetate the true colours were revealed. The photo doesn’t really ...

Zelia sp. (fg-taxon #1)

Zelia sp. (fg-taxon #1)
This taxon is a dexine tachinid with unusual markings on T3 and an elongate abdomen. It also has plumose antennae.

Beskia aelops (fg-taxon #44) 2

Beskia aelops (fg-taxon #44)
This is a strange dexiine tachinid with and extremely long proboscis and long antennae. The curl on this specimen’s antennae may have been caused by the drying process when it was taken out of alcohol – I only have one specimen of this taxon so I have nothing else to compare it with. UPDATE (30/1/2010): ...
