Some interesting flies from Paraguay

Some interesting flies from Paraguay
Today I received a small parcel of Diptera from Ulf in Paraguay – many thanks Ulf! 🙂  In the mix were lots of different families but he had sorted out mainly the calyptrates for me … with an emphasis on the tachinids, of course. Here are the first specimens from the parcel – 2 Tachinini ...

Archytas aurifrons, Townsend

Archytas aurifrons, Townsend
Last week I spent a happy afternoon at the BMNH, courtesy of Erica & Nigel in the Diptera department. I decided to concentrate on a few genera and try to identify a few neotropical specimens. My first was Archytas, a large genus with many very similar species, because I have a few quite atypical taxa ...

Archytas (French Guiana & Brazil)

Archytas (French Guiana & Brazil)
The following is a selection of Archytas sp. from both French Guiana and Brazil showing some of the immense diversity of this genus. Despite their huge variability Archytas spp. usually have a characteristic change in colouration between tergites 1-4 and tergite 5 – the whole abdomen is shiny but tergites 1-4 have a faint, pale ...

Archytas aurifrons, Townsend (pe-taxon #24)

Archytas aurifrons, Townsend (pe-taxon #24)
This is another tachinine tachinid with a slightly variable abdomenal patternation but there and many fundamental similarities between the 2 featured specimens – taking into consideration that one is male and the other is female. This taxon is very similar to fg-taxon #80. EDIT (6/8/2011): After a visit to the BMNH I believe this to ...

Archytas aurifrons (fg-taxon #80) 1

Archytas aurifrons (fg-taxon #80)
This nice little tachinid looks very like a Tachininae – similar to fg-taxon #20 but with more black on the abdomen. EDIT (Monty Wood 26/9/2010): These are an Archytas sp. EDIT (6/8/2011): After a visit to the BMNH I believe these to be Archytas aurifrons, Townsend.

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.:
