Diploglena dippenaarae is a species of spider of the genus Diploglena. It is endemic to the Western Cape province of South Africa.
The species is named in honour of Ansie Dippenaar-Schoeman, a prominent South African arachnologist who has made significant contributions to the study of African spiders.
Diploglena dippenaarae is known only from two localities near Saldanha Bay: Jacobsbaai and Saldanha. The species appears to have a very restricted distribution.
The species is a free-living ground dweller sampled at night from leaf litter in coastal Fynbos Biome.
Diploglena dippenaarae is listed as Endangered under criterion B due to its restricted distribution. The species is only known from two localities near Saldanha Bay at elevations ranging from 3 to 8 metres above sea level. It appears to have a restricted distribution and more sampling is needed to determine the species range. A precautionary status of Endangered is assigned due to high rates of habitat transformation taking place at the two known locations.
Both males and females are known for this species.
