Udubidae is a family of araneomorph spiders, most of whose members were formerly placed in the family Zorocratidae, which is no longer accepted. ==Phylogeny== A study investigating the phylogenetic relationships of lycosoid spiders concluded that the genera formerly placed in the family Zorocratidae fell into two groups. The largest group formed the sister clade to the "grate-shaped tapetum clade" (see the cladogram below). The type genus, ''Zorocrates'', grouped with ''Zoropsis'' inside the grate-shaped tapetum clade.〔 Some earlier studies had also cast doubt on the monophyly of the Zorocratidae. A 2003 study found that ''Raecius'', ''Uduba'', and ''Zorodictyna'' formed a clade somewhat separated from ''Zorocrates''. A 2014 study including ''Zorocrates'' and ''Raecius'' did not find that they grouped together.〔, p. 289〕 Moving the type genus to a different family meant that a new family name was needed for the remaining members. Griswold and Polotow proposed "Udubidae", with the type genus ''Uduba''.〔 , the World Spider Catalog accepted this family.〔 A summary phylogeny is shown below.〔 }} }} }} (Shading marks genera formerly placed in Zorocratidae.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Udubidae」の詳細全文を読む スポンサード リンク
