Emertonius

Emertonius is a genus of spiders in the jumping spider family Salticidae.^[1]

Taxonomy

Emertonius was first described by George and Elizabeth Peckham in 1892.^[1] It was variously treated as a synonym of Myrmarachne or a separate genus from 1978 onwards. Jerzy Prószyński revalidated the genus in 2018,^[2] and it is accepted by the World Spider Catalog as of August 2020.^[1]

When included in Myrmarachne, it was placed in subfamily Salticinae (clade Salticoida, tribe Myrmarachnini) in Maddison's 2016 classification of the family Salticidae.^[3] Prószyński placed the separate genus in his informal group "myrmarachnines".^[2]

Species

As of August 2020, the World Spider Catalog accepted the following extant species:^[1]

• Emertonius exasperans (Peckham & Peckham, 1892) (type species) – Indonesia (Java, Bali)
• Emertonius koomeni Prószyński, 2018 – Malaysia (Borneo)
• Emertonius malayanus (Edmunds & Prószyński, 2003) – Malaysia (peninsula, Borneo), Indonesia (Sumatra, Borneo)

Le 5 specie sono state reperite in Asia sudorientale: Malesia, Indonesia e Filippine^[1].

Tassonomia

Per la descrizione delle caratteristiche di questo genere sono stati esaminati gli esemplari tipo di E. exasperans Peckham & Peckham, 1892^[1].

Questo genere è ritenuto sinonimo posteriore di Myrmarachne MacLeay, 1839 a seguito di un lavoro di Wanless (1978b) (per un punto di vista alternativo al riguardo, consultare il lavoro degli aracnologi Prószyński, J. & Deeleman-Reinhold, C.L., del 2010 e quello di Edwards del 2013)^[1].

Non sono stati esaminati esemplari di questo genere dal 2019^[1].

Attualmente, a gennaio 2022, si compone di 5 specie^[1]:

• Emertonius exasperans Peckham & Peckham, 1892^[2] — Indonesia (Giava, Bali)
• Emertonius koomeni Prószynski, 2018 — Malesia (Borneo)
• Emertonius malayanus (Edmunds & Prószynski, 2003) — Malesia (parte peninsulare, Borneo); Indonesia (Sumatra, Borneo)
• Emertonius palawensis Prószynski, 2018 — Filippine
• Emertonius shelfordi (Peckham & Peckham, 1907) — Malesia (Borneo)
