Distribution and Ecology - Distribution. Known only from the type locality and the geographically proximal Cerros Guanay and Camani.

Discussion:Stegolepis pulchella and S. membranacea are readily distinguished from S. hitchcockii because of its strongly coriaceous leaf-blades with inconspicuous midrib primary veins.
