Mallobathra aphrosticha

This species was first described by Edward Meyrick in 1912 and named Telapora aphrostcha, a misspelling in the original publication.[3][2] He used specimens collected by Alfred Philpott at Hump Ridge in Fiordland at an altitude of 3500 ft.[4] Not long after publication, the spelling of aphrosticha was used in scientific literature to refer to this species.[4] Dugdale discussed this misspelling stating that the appropriate spelling of the species name is aphrositcha as indicated by Mayrick's handwriting on a specimen label.[2] In 1971 this species was placed within the genus Mallobathra.[5] This name was confirmed by the New Zealand Inventory of Biodiversity.[1]
