EGL, EGU. Apparently confined to Gippsland, from around Nowa Nowa eastward. Grows in open forest, usually with a shrubby understorey. Exact range still to be determined.

Distinguished from Pterostylis chlorogramma (and similar P. smaragdyna) by the distinctly reddish labellum and sepal tips and the thickened, incurved margins of the labellum.
