Permarachne is an extinct genus of arachnids containing the single species Permarachne novokshonovi from the Permian ( Kungurian) of Russia, found in the Koshelevka Formation near the town of Suksun in Perm Krai. It is closely related to modern spiders but unlike them, it has a long thin tail, similar to its relative Attercopus, it is known from the mostly complete holotype PIN 4909/12. [1] It is about 1 cm in size. It initially was thought to be a spider, but is now thought to form a clade with at least its close relative Attercopus, forming the grouping Uraraneida. [2]
