Thread subject: Diptera.info :: Asilidae (southwestern France) identified (Neomochterus & Machimus) (thread 2 of 2)

This smaller species, ~15mm TL, than the previous two species was also snapped in the same coastal sandy environment by a small 'lake' (more swamp like) surrounded by a pine plantation; the precise locals being 'Reserve naturelle de l'Etang Cosseau, Aquitaine, France' on 24 August '14. This is the same individual (so there is no chance of me confusing both species and sexes this time :) ), but the species, or at least this individual, was far less obliging than the former two (not allowing me to get anywhere near as close), so the images are already seriously cropped (~ 50%) and the resolution comparably poor. Sorry about the random stick in frame in the upper image ....

Again, any assistance with an identification would be appreciated. Thanks in anticipation.

This may well be another specimen of the same species, from neighboring Biscarros (same habitat, basically same locals) taken on 16 August.

And several more from the same general region (Lacanau) that I assume are conspecific

The lowest are of a female Neomochterus. The photos have some issues, so I'd say N. cf. pallipes, but cannot swear it.

photos 1-2 are 2 Machimus complex flies; female and male respectively.

Thank you so much. I have learned my lesson never to post images of more than one specimen in a given thread. I have a lot of reading to do.

Kindest, Me

1&2:

Tolmerus cf atricapillus female
Tolmerus atricapillus male

Nr 3:

Tolmerus sp. maybe atricapillus (but it looks very "red" and the ovipositor also looks a bit reddish) or pyragra or micans.

Nr 4 & 5

Neomochtherus or maybe even Cerdistus. I can't see enough to make a statement about this one. Sternites seem to be dusted but i can't be sure, occipital bristles seem to be white but i am not sure. It has a remarkable large ovipositor.
