This reference has a drawing that I will try to add later - the comments included (there is no real description in this reference) :
It starts with a list of 4 specimens and then :
" The type from the Bismark Range (no. 13933) is not well preserved, but I have no doubt that all the specimens enumerated here belong to the same species.Â
The first description still has to be modified a little. The sepals, as well as the ovary, are covered with short papillae on the outside. The petals towards the apex are irregular on the edges, almost toothed, the labellum is nearly two lobed through a depression in front. The flowers are probably the smallest among the know species of the section."
This is a cropped version of one flower - I have adjusted the image so that we can see details a bit more - the flower is about 1mm, yes that's right , in natural spread.
