Thalassarche eremita Chatham Albatross Murphy 1930
Family: Diomedeidae

Taxonomy

Thalassarche eremita Murphy 1930 is generally accepted nomenclature for the Chatham Albatross (ACAP 2012h). There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Thalassarche cauta eremita Murphy 1930. The Chatham Albatross was considered polytypic until it was included in the resurrected genus Thalassarche (Reichenbach 1852) at the specific level as Thalassarche eremita based on morphology and demographic differences, and genetic analyses (Robertson & Nunn 1998). ACAP has concluded on advice from its Taxonomy Working Group that available data warrant recognition of Chatham Albatross at the specific level with the nomenclature generally accepted (Brooke et al. 2007, ACAP 2012h).
