Triaeris is a genus of spiders in the family Oonopidae. Its taxonomy is confused, and the number of species that should be placed in the genus is unclear.

Taxonomy
The genus was erected by Eugène Simon in 1890 for the species Triaeris stenaspis. It was described from females from the Lesser Antilles; specimens were found later in heated greenhouses around Europe. No males of T. stenaspis have ever been found and the species may be parthenogenetic.
In 2012, Norman I. Platnick and co-authors described the genus Triaeris as "an enigma wrapped around a mystery". They consider that most species assigned to the genus after Simon in 1890 and before 2012 do not belong to Triaeris.
Species
As of April 2016, the World Spider Catalog accepted the following species. The assignment to groups is based on Platnick et al. (2012).
