Stefan,
When you say the D. glabripes in the photo.....do you mean in Martin's photo? This seems to conform to what I know of as D. glabripes, and I cannot see anything remotely similar to D. venusta in these plants! If you are referring to MArtin's photo, could you be so kind as to explain how you arrived at your determination? The South African species can be confusing, but surely not this confusing!
(I have been uncertain of everything since learning that D. nidiformis and D. dielsiana were long considered synonomous!
Please have a look at these photos, and let me know if you believe any of them are D. glabripes? I believe they are.

(the lamina are broader than my plants, but note the stipules!

(these plants seem closest to what I grow as this species)

I note in most of these photos the presence of fine, verticle white stipules which seems the most observationally distinct feature.
Drosera venusta I have always considered a form of D. natalensis and in habit is less caulescent, although it holds the top leaves erect. I find Tony's photo to be fairly typical of most D. venusta I have seen.
Stefan, thank you very much for your input on this subject that is very dear to my heart. I hope someday to arrive at some sort of peace with the taxonomy of the South African species, and any help is deeply appreciated!
I await your email eagerly!
