Sitticini
The Sitticini are a tribe of spiders in the family Salticidae (jumping spiders). 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. Description The group is now primarily defined by molecular phylogenetic analysis. However, members can be distinguished from other salticids by the fourth leg being much longer than the third and by the absence of the retromarginal cheliceral tooth. Taxonomy The group was first described by Eugène Simon in 1901, under the name "Sitticeae". It was treated as the subfamily Sitticinae by various authors before being reduced to the tribe Sitticini by Wayne Maddison in 2015. The taxonomy of the tribe has been subject to considerable uncertainty; generic boundaries were changed repeatedly between 2017 and 2020. ...

Attinella
''Attinella'' is a genus of North American jumping spiders. It was first described by Nathan Banks in 1905 based on the type species '' Attinella dorsata'' (originally ''Attus dorsatus''). it contains only three species: '' A. concolor'', '' A. dorsata'', and '' A. juniperi''. It was synonymized with '' Sitticus'' from 1979 to 2017, when the genus ''Sittiab'' was split from ''Sitticus'' by Prószyński in 2017, and ''Attinella'' was recognized as its senior synonym. Phylogeny ''Attinella'' is placed in the tribe Sitticini within the family Salticidae. In 2020, Wayne Maddison and co-workers divided the tribe Sitticini into two subtribes, Aillutticina and Sitticina. ''Attinella'' was placed in Sitticina, within a clade whose sister was the genus '' Attulus''. The relationship between these taxa is shown in the following cladogram.

Attulus
''Attulus'' is a genus of jumping spiders that was first described by Eugène Louis Simon in 1889. The name is a diminutive form of a common prefix for salticid genera, '. Taxonomy In 1889, Eugène Simon separated the genus ''Attulus'' from the genus '' Attus''. The correct name of the type species involves some taxonomic complexity. Simon gave ''Attus cinereus'' Westring, 1861 as the type of the genus. However, this name had already been used by Walckenaer in 1837 for a different species, so Simon's 1871 replacement name ''Attus helveolus'' is used instead. ''A. helveolus'' is now regarded as the same species as ''Attus distinguendus'', described by Simon in 1868, so having priority as a name. Thus the type species is currently known as ''Attulus distinguendus''. Within the family Salticidae, ''Attulus'' is placed in the tribe Sitticini (the sitticines). The taxonomy of the tribe and the genus ''Attulus'' has been subject to considerable uncertainty; some species changed ge ...

Nosferattus
''Nosferattus'' is a genus of Brazilian jumping spiders that was first described by G. R. S. Ruiz & Antônio Domingos Brescovit in 2005. The name is a combination of "Nosferatu" and the ending ''-attus'', a common salticid genera suffix. They range from long. Males have a smooth, oval-shaped plate (scutum) on the upper surface of the opisthosoma (abdomen). ''Nosferattus'' can be distinguished from other genera in the tribe Sitticini by the presence of highly flattened pedipalps in males, and very long and coiled copulation ducts in females. They are likely related to '' Aillutticus'', which also has a high, broad carapace, rounded laterally behind the posterior lateral eyes, and a slightly convex cephalic region. Species it contains five species, found only in Brazil: *'' Nosferattus aegis'' Ruiz & Brescovit, 2005 – Brazil *'' Nosferattus ciliatus'' Ruiz & Brescovit, 2005 – Brazil *'' Nosferattus discus'' Ruiz & Brescovit, 2005 (type Type may refer to: Science and technol ...

Attulus Floricola
''Attulus floricola'' is a species of jumping spider (family Salticidae) with a Palearctic distribution. They are typically in length. Females are dark reddish brown, with an almost black anterior.

''Tomis'' is a genus of South American jumping spiders that was first described by F.O. Pickard-Cambridge in 1901. The genus ''Pseudattulus'', erected by Lodovico di Caporiacco in 1947, was formerly considered distinct with two species, but was placed in synonymy in 2020 when ''Tomis'' was re-separated from ''Sitticus'' (now '' Attulus'').

Wayne Maddison
Wayne Paul Maddison , is a professor and Canada Research Chair at the departments of zoology and botany at the University of British Columbia, and the Director of the Spencer Entomological Collection at the Beaty Biodiversity Museum. His research concerns the phylogeny, biodiversity, and evolution of jumping spiders (Salticidae), of which he has discovered new species and genera. He has also done research in phylogenetic theory, developing and perfecting various methods used in comparative biology, such as character state inference in internal nodes through Maximum parsimony (phylogenetics), maximum parsimony, squared-change parsimony, or character correlation through the concentrated changes test or pairwise comparisons. In collaboration with David R. Maddison, he worked on thMesquiteopen-source phylogeny software, thMacCladeprogram, and the Tree of Life Web Project. His research has led him to discover new species of jumping spiders in Sarawak and Papua New Guinea. Selected pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
