pe-taxon #32 (Peru)

pe-taxon #32 (Peru)
This is a lovely little taxon, with matt-black ground colour and bright pale-grey bands of dusting on the thorax and abdomen. It fails to achieve a convincing result in MCAD.

possibly Hyphantrophaga sp. (Peru)

possibly Hyphantrophaga sp. (Peru)
This keys to Hyphantrophaga sp. but it needs confirming. EDIT (6/01/2011): Monty has said that this genus is quite anonymous and difficult to split … but they sometimes have hairs on the hind coxa (like Carcelia) and one of my 2 specimens does have this feature so I am tentatively assigning them to Hyphantrophaga.

3x Mystacella sp. (Peru)

3x Mystacella sp. (Peru)
These photos illustrate 3 species of Mystacella – a tachinid that, like Chrysoexorista, is a beautiful metallic green (sometimes across the whole body, but at the very least on the thorax) in life but this fades to golden brown when dead. Mystacella have the vibrissae emerging quite high above the mouth edge and a very ...

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 ...

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.

probably Arrhinactia sp. (Peru)

probably Arrhinactia sp. (Peru)
This is quite a distinctive and very common taxon in the peruvian samples. The fly has a clear dusting pattern and the tip of the abdomen is laterally compressed and knife-like. Det: Monty Wood, 2010.

Pennapoda sp. ??? (pe-taxon #30)

Pennapoda sp. ??? (pe-taxon #30)
This little phasiine is undoubtably a member of the Trichopodini, from the leaf-like bracts along the hind tibiae. This is very similar to some of the taxa from French Guiana – namely fg-taxon #8 #9 & #43. EDIT (04/10/2010): This keys quite comfortably to Homogenia sp. but it is much smaller than the other Homogenia ...

Souzalopesmyia sp. (Muscidae, pe-taxon #29) 1

Souzalopesmyia sp. (Muscidae, pe-taxon #29)
This is a very unusual (dexiine?) tachinid with plumose aristae, deep gena, tiny calyptrae & a straight median vein. See also pe-taxon #10 – a very similar tachinid with a brown body colour. EDIT (09/10/2010): After showing this to Adrian Pont he thinks that they most resemble muscids but will do further research and report ...

Ebenia sp. (pe-taxon #28)

Ebenia sp. (pe-taxon #28)
This is a small, black tachinid with plumose antennae, suggesting Dexiinae. These are photos of both the male and the female. EDIT (04/10/2010): This keys very confidently to Ebenia and looks very similar to one identified by Monty. This genus has been reared from chrysomelid beetles.

pe-taxon #27

pe-taxon #27
This tiny little tachinid (2mm) has very unusual wings – very wide, like Phasia spp., with mottling around the SC vein, but it clearly isn’t a phasiine.

Phytomyptera sp. (pe-taxon #26)

Phytomyptera sp. (pe-taxon #26)
This is a very small (3-4mm) tachinid with nothing particularly exceptional about it but it does have a very distinctive, long second arista segment, rather like Triarthria sp. EDIT (04/10/2010): This keys very confidently to Phytomyptera sp.

Pelecotheca (Cryptocladocera) sp. male (pe-taxon #25)

Pelecotheca (Cryptocladocera) sp. male (pe-taxon #25)
This is the only Cryptocladocera in the peruvian sample and it looks very like the ones from French Guiana – fg-taxon #04.

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 ...

Deopalpus sp. (pe-taxon #23)

Deopalpus sp. (pe-taxon #23)
Another medium-sized tachinine tachinid – this time with a white-dusted head. The body is shiny, jet black, there are Peleteria-bristles and the tip of the abdomen is slightly fuscous. Det: Monty Wood, 2010.

Itacuphocera (pe-taxon #22)

Itacuphocera (pe-taxon #22)
This is a lovely, tiny little tachinine tachinid – shiny, jet black all over with a yellow head and red eyes. Unusually for this subfamily it also has a petiole on the median vein. In fact the median vein has a completely remarkable shape. EDIT (04/10/2010): This isn’t a great fit but it seems to ...

Pyrrhodexia & Acronacantha nubilipennis (pe-taxon #21)

Pyrrhodexia & Acronacantha nubilipennis (pe-taxon #21)
This is an amazing dexiine with a very Estheria-type face – small antennae, plumose arista, very deep gena, very chin-less profile and a very stretched-out ‘top lip’ with a second, higher pair of vibrissae. The bend in the median vein is quite acute and the part of m after the bend is very concave. There ...

Calodexia sp. (pe-taxon #20)

Calodexia sp. (pe-taxon #20)
This is a close relative of fg-taxon #98 with its rounded abdomen, large eyes and downward-pointing ovipositor. EDIT (09/10/2010): This is undoubtedly a female Calodexia sp. http://chrisraper.org.uk/blog/?p=2495

Winthemia & Winthemiini (pe-taxon #19)

Winthemia & Winthemiini (pe-taxon #19)
This taxon is clearly related to the other taxa with very prominent Sturmia-spots – especially fg-taxon #14 EDIT (04/10/2010): This taxon comprised 4 Winthemia sp. EDIT (17/10/2010): The odd specimen originally keyed to “Lydella” but is now just “Winthemiini” after chatting with Monty Wood. This specimen needs running through Guimaraes’ 1983 revision of some Winthemiini.

pe-taxon #18

pe-taxon #18
This is an interesting taxon with a very distinctive, dark patch of bristles on the underside of tergites 4 & 5 – rather like a broad Sturmia-spot. EDIT (09/10/2010): This vaguely resembles a Masiphya, with its Sturmia-spot and a few other bristle arrangements – but it has to many differences for me to place it more ...
