Phellopsis
Phellopsis is a genus of zopherid beetles established by J.L. LeConte in 1862. The genus contains approximately seven recognized species distributed across North America and Asia. North American species P. obcordata and P. porcata are vicariant taxa restricted to old growth boreal forests of eastern and western North America, respectively. These species were historically confused until a 2008 revision clarified their distinct status. Asian species include P. amurensis (Russian Far East to Korea), P. suberea (Japan), P. chinense (west-central China), and P. yulongensis (Yunnan Province).
