Pelecotheca s.g. Cryptocladocera (male) (Surinam)

Pelecotheca s.g. Cryptocladocera (male) (Surinam)
The Surinamese batch of flies from Menno yielded quite a lot of male Cryptocladocera – here are just 2.

Here is Dave’s latest version of the Pelecotheca (Cryptocladocera) male – looking even better. To see Dave’s other photos click here.

Stacking / compositing photographs
Recently a local photographer called Dave Dare got in touch with me to ask if I could lend him some specimens so that he could practice macro photo stacking/compositing. This seemed a great opportunity for me to help someone out and also have some of my favourite specimens photographed with very deep focus. Dave has ...

Neomintho macilenta (French Guiana)

Neomintho macilenta (French Guiana)
This genus is related to the multi-fissicorn genera, like Cryptocladocera & Cerotachina (all members of the Neominthoini but most do not have multi-fissicorn antennae) . This species is distinguished by having a completely black T5. Determination by Monty Wood.

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 flavipes Thompson (Neominthoini, pe-taxon #16)

Pelecotheca flavipes Thompson (Neominthoini, pe-taxon #16)
After keying this taxon through MCAD it looks like one of the Neominthoini (it emerges on Neomintho, where most Neominthoini will end up) and the strong bristles on the facial ridges and the very elongate antennae are reminiscent of the females of the Pelecotheca group of species. All of the specimens in this species group are ...

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 ...

Pelecotheca (prob. Cryptocladocera) sp. female (fg-taxon #90)

Pelecotheca (prob. Cryptocladocera) sp. female (fg-taxon #90)
This one is unusual because the abdomen is tipped with a strange, shiny, flattened structure that resembles a squashed tube. EDIT (Monty Wood 26/9/2010): This is an example of a female Pelecotheca (probably the female of the large multi-fissicorn featherfaces so sub-genus Cryptocladocera). The flattened shiny structure is distinctive of this group of sub-genera.

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 ...
