Nupela
Nupela is a genus of diatom. Species of Nupela typically measure less than 20 μm. The genus was first described as being isovalvar, however many recently described species are heterovalvar. The main diagnostic characteristic of the genus is the presence of an external covering over the areolae. The genus was circumscribed by Wim Vyverman and Pierre Compère in 1991, with Nupela giluwensis assigned as the type, and at that time, only species.
Nupela was originally described from high elevation ponds in Papua New Guinea. Since then, Nupela has been found in waters with a neutral pH and low conductivity throughout Europe, South America, North America, Asia and Africa. Five newly described species from Yunnan China were added to the genus in 2022.
