My first stacks
Yesterday Malcolm Storey (bioimages.org.uk) brought over some new equipment he had just bought for photo-stacking, along with a ‘kit’ including a spare dSLR (3MP Nikon D100) and macro lenses. The real star of the equipment is Malcolm’s new StackShot – an automated system for racking a camera through pre-defined focus points and taking the photos ...

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 ...
