Theuma cedri is listed as Least Concern by the South African National Biodiversity Institute. Although the species is presently known only from one sex, it has a wide geographical range. There are no significant threats to the species, but more sampling is needed to collect the male. It is protected in Namaqua National Park and Cederberg Wilderness Area.

The species was originally described by William Frederick Purcell in 1907 from Boschkloof Waterfall in the Cederberg in the Western Cape. It has not been revised and is known only from the female sex.
