Since nobody answered me, I'll answer myself...
I obtained 2 different Heli keys, one from unknown origin through a friend, and another from CPN written by William Baumgartl. Both were rewritten/ adapted for this webpage by me. Enjoy!

KEY 2

6.) A-- Lid well-developed ......H.heterodoxa var.heterodoxa
B-- Lid minimally developed ………………………………....……..7
7.) A-- Throat pubescent ...................................... H.heterodoxa var. exappendiculata

8.) A-- Throat glabrous above pubescent ring or with hairs of equal length ….………..………………...…………...…...................9
B-- Throat pubescent, hairs tapered in length from 0.2-1.0mm at the top to 1-1.5 at pubescent ring……………………10
9.) A-- Throat glabrous above pubescent ring ……..................… H.tatei var.tatei f.macdonaldae
B-- Throat pubescent with hairs of equal length ………...............… H.tatei var.tatei f.tyleri
10.) A-- Pitcher exterior pubescent …………………………….…................ H.tatei var.neblinae
B-- Pitcher exterior glabrous ……………………...…................ H.tatei var.neblinae f.parva
And what about H.tatei var.neblinae, how does this one supposedly differ, what characters identify it? I noticed in Jan Schlauer's CP database that he also considers valid H.tatei var.neblinae f.parva, anybody know why? Last of all, I noticed that another taxa has been described from Duida: H.tyleri. What was claimed different in this one?
