Utivarachna

Utivarachna is a genus of Asian araneomorph spiders in the family Trachelidae first described by Kyukichi Kishida in 1940.[2] It was largely ignored until Christa L. Deeleman-Reinhold revised the sac and ground spiders in 2001, transferring some species from Trachelas and adding several new ones.[3] The genus was further expanded in 2014 and 2015.[4][5]
