I am also looking to understand this term for Hydrotaea- normal pair of rigid processes at apex beneath- referring to femur 1

Does anyone have a photo that shows this?

Again thanks for your time

Most Hydrotaea males have an outward-facing hook near the apex of the front femur. If you look at it from beneath you can see that it is, in fact, a pair of hooks which are rigidly attached to the rest of the femur. That is what is meant by the "pair of rigid processes". Once seen, easily recognised.

it's the sharp spike with what seem to be 2 bosses behind it! it's quite an interesting feature who would of thought of that on a fly

Also looking at the Fonseca key are H armipes and occulta the same fly

the key distinguishes the 2 using several characteristics but the checklist comes up with armipes H occulta!

Thanks again

The two species of Fonseca's key were synonymised by Pont in 1984, so they are now officially the same species - H. armipes.

Thanks Howard, that explains that and at least 1 Hydrotaea that's easy to spot!
