Amycoida is an unranked clade of the jumping spider family Salticidae. It is the smaller and less widespread of the two subdivisions of the "typical" jumping spiders (subfamily Salticinae), occurring mainly in the New World, particularly the Amazon basin. Its sister clade is the Salticoida. [1]

Definition

Amycoida is formally defined as the smallest clade containing Cotinusa , Sitticus , Breda , Sarinda , Synemosyna , and Amycus . [2]

Subdivisions

Amycoida is divided into nine tribes, with about 63 genera (two of which are unplaced in a tribe) and about 430 described species. Many more species are thought to be undescribed as yet. Sitticini has the largest number of species (about 120). It is the only tribe to have reached the Old World, particularly the genus Attulus (formerly Sitticus). Amycini has the next largest number of species (about 110). Amycines are mostly foliage-dwellers. Many are excellent jumpers; Wayne Maddison recorded a 5.2 mm juvenile Hypaeus species jumping 25 cm on a horizontal surface (more than 45 times its body length). [1]

<span class="mw-page-title-main">Salticinae</span> Subfamily of spiders

Salticinae is a subfamily of jumping spiders. It includes over 90% of the known species of jumping spiders. The subfamily is divided into two unranked clades: Amycoida and Salticoida.

<span class="mw-page-title-main">Salticoida</span> Clade of spiders

Salticoida is an unranked clade of the jumping spider family Salticidae. It is the larger and more widespread of the two subdivisions of the "typical" jumping spiders, occurring effectively world-wide. Its sister clade is Amycoida, which is also very diverse ecologically but has a mostly South American distribution.

Simonellini is a tribe of spiders belonging to the Amycoida clade of the subfamily Salticinae of the family Salticidae. The group has been treated at a variety of formal and informal ranks, with different circumscriptions, including as the subfamilies Synemosyninae and Simonellinae. Its species mimic ants and beetles.

Ragatinus is a genus of spiders in the family Salticidae. It was first described in 2016 by Angelika Dawidowicz and Wanda Wesołowska. As of 2017, it contains only one species, Ragatinus maddisoni.

Edwardsya is a genus of spiders in the family Salticidae. It was first described in 2016 by Ruiz & Bustamante. As of 2017, it contains 2 species, both from Brazil. The genus is placed in subtribe Freyina, part of the Salticoida clade in the subfamily Salticinae.

Hermosa is a genus of jumping spiders first described by G. W. Peckham and E. G. Peckham in 1892, and synonymized with Myrmarachne in 1901. In 2016, Jerzy Prószyński split up Myrmarachne, creating nine new genera, all with names beginning "Myrm". However, it turned out that Myrmavola volatilis, the type species of Myrmavola, was also the type species of Hermosa, and Myrmavola was made a junior synonym. It is part of the Myrmarachnini tribe within the Salticoida clade of Salticinae.

<i>Stenaelurillus ignobilis</i> Species of spider

Stenaelurillus ignobilis is a species of jumping spider in the genus Stenaelurillus that lives in Zimbabwe. The female was first described in 2011 by Wanda Wesołowska and Meg Cumming. The male has yet to be described. The spider takes its name from a Latin word that can be translated unsightly. The spider is medium-sized, with a carapace 2.6 mm (0.10 in) long and abdomen 3.4 mm (0.13 in) long. The carapace is brown, covered in bristles and has an almost indiscernible stripe, while the abdomen is larger and has a stripe of lighter brown down the middle of its generally darker, nearly black, The long spinnerets are also hairy while the legs have both hairs and spines. It is similar to Stenaelurillus mirabilis but can distinguished by the design of the epigyne, and particularly the way that the gonopores are hidden in deep cup-like depressions.

<i>Stenaelurillus striolatus</i> Species of spider

Stenaelurillus striolatus is a species of jumping spider in the genus Stenaelurillus that is endemic to Nigeria. It was first described in 2011 by Wanda Wesołowska and Anthony Russell-Smith. Only the male has been identified. The spider is small, with a brown cephalothorax 2.5 mm (0.098 in) in length and black abdomen 2.4 mm (0.094 in) in length. The abdomen is marked with two shining white stripes which give the species its name. It is distinguished from other members of the genus by its clypeus, which is entirely dark brown and black.

<span class="mw-page-title-main">Sitticini</span> Tribe of spiders

The Sitticini are a tribe of spiders in the family Salticidae. The tribe has been divided into two subtribes, Aillutticina, with five Neotropical genera, and Sitticina, with five genera from Eurasia and the Americas. One genus is unplaced within the tribe. The taxonomy of the tribe has been subject to considerable uncertainty. It was clarified in 2020.
