Atractopyge is a genus of trilobites that lived in what would be Asia and Europe from the middle Ordovician to the early Devonian from 472 to 412.3 mya, existing for approximately {{Mya|472-412.3|million years}}.[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=21451 PaleoBiology Database: Atractopyge, basic info]
Taxonomy
Atractopyge was named by Hawle and Corda (1847).Hawle, I. & Corda, A. J. C. 1847. Prodrom einer Monographie der böhmischen Trilobiten. J. C. Calve, Prague. Jell and Adrain (2003) list it as a currently valid genus name within the Phacopida, specifically within the Encrinuridae.Jell, P. A. and Adrain J. M. 2003. Available generic names for trilobites. Memoirs of the Queensland Museum 48(2): 331 - 553.
Fossil distribution
Fossil distribution is confined to the strata of the Early Llanvirn to Rawtheyan ages. Fossils have been recovered from Yunnan Province, China to the Stinchar River, United Kingdom to Ringerike, Norway.
History
A cranidium of Atractopyge was already illustrated by the Welsh scientist Edward Lhuyd in 1698.{{cite web|title= The Ordovician trilobite Atractopyge from Wales and northern England|author= R. M.

The species xipheres is commonly referenced as A. Xipheres (Öpik, 1937), particularly on commercial websites. However, Öpik first described the species in 1925 as Cybele xiphere (Öpik, 1925, pp. 11, fig. 1: 10, 11)Öpik, A. A. 1925. Beiträge zur Kenntnis der Kukruse-(C2-) Stufe in Eesti. I. Acta et Commentationes Universitatis Tartuensis VIII, 5, 1 - 18. and later (1937, pp. 121, fig. VII 3; XXI 3, 4) described the species as Cybele (Atractopyge) xipheres sp. nov.Öpik, A. A. 1937.
