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.

Multifissicorn tachinid faces (Pelecotheca s.g. Cerotachina & Cryptocladocera)

Multifissicorn tachinid faces (Pelecotheca s.g. Cerotachina & Cryptocladocera)
This is a little post just to show the range of antennal branching in different multifissicorn tachinids – apologies for the poor quality of the photos. As you can see, Cryptocladocera spp. have huge branches on their antennae while both of the 2 new species have much shorter antennal branches, which seems closer to the ...

Pelecotheca (Cerotachina) sp. male (pe-taxon #14)

Pelecotheca (Cerotachina) sp. male (pe-taxon #14)
This appears to be another new, hitherto undescribed, species closely related to Cerotachina – it has no median discals and antenna-3 is very shallowly multifissicorn. That is, the third antennal segment has bumps on both sides covered with tufts of long hairs. These bumps are shorter than the branches on my French Guianan Cerotachina and ...

Cerotachina sp. (fg-taxon #97) 1

Cerotachina sp. (fg-taxon #97)
This little gem is another multifissicorn species with feathered antennae – similar to the other ‘featherface’ tachinids, like Borgmeiermyia and Cryptocladocera. However, after running this through Arnaud (1963) it keys out as Cerotachina but doesn’t conform to either of the 2 known species so I am considering this a new, as yet undescribed species. In ...

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 ...
