Pescennina is a genus of spiders in the family Oonopidae. It was first described in 1903 by Simon. As of 2017 [update] , it contains 18 species. [1]
Pescennina comprises the following species: [1]
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Triaeris macrophthalmus is a species of spider from the family Oonopidae. It was described by Lucien Berland in 1914 and is endemic to Tanzania. 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 following Simon in 1890 and before 2012 do not belong to Triaeris, including T. macrophthalmus, which they suggest belongs to one of a group of related genera. As of April 2016, no alternative generic assignment has been accepted by the World Spider Catalog.
Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes. In some species the number of eyes will increase when the spiderling changes its skin as it grows towards adulthood.
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. 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.
