Dioxycanus fusca

Dioxycanus fusca is a species of moth of the family Hepialidae. It is endemic to New Zealand.[1] This species was first described by Alfred Philpott in 1914 as Porina fusca using specimens collected by C. Fenwick and M. O. Pasco.[2] In 1966 L. J. Dumbleton reviewed New Zealand Hepialinae and placed this species within the genus Dioxycanus, giving it the new combination Dioxycanus fuscus.[3]

Larvae have been found amongst short Poa tussocks, living in shafts in the soil.[4]
