Triaeris

Triaeris is a genus of goblin spiders 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.[2] Its taxonomy is confused, and the number of species that should be placed in the genus is unclear. 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.[2]
