Seycellesa braueri

S. braueri is endemic to the Seychelles, where it is found on the islands of Mahé and Silhouette at elevations of 300 to 500 m (980 to 1,640 ft). The type locality for S. braueri is Mahé; the type locality for the junior synonym S. purifum is Morne Seychellois, central Mahé. Its habitat is woodland.

The type species was initially described in 1898 by the French naturalist Eugène Simon, who placed it in the genus Theridion. He chose the specific epithet braueri to honor A. Brauer at the University of Marburg. His description was based on a male specimen. British arachnologist Michael Roberts described a junior synonym, T. purifum, in 1978. The specific name was described as "an arbitrary combination of letters". His description was based on a female specimen. Michael Saaristo synonymized T. purifum with T. braueri in 1999. In 2006, Saaristo circumscribed a new genus for T. braueri. He named it Robertia after Michael Roberts. However, that generic name was invalid due to a senior homonym: the synapsid genus Robertia. In 2008, Ahmet Koçak and Muhabbet Kemal created a nomen novum for this genus: Seycellesa.
