Wiseana is a genus of ghost moths, collectively known as porina, of the family Hepialidae. There are seven described species, all endemic to New Zealand. Some species of this genus are a major pest in New Zealand exotic pastures. It is impossible to distinguish species at the larval/caterpillar stage without DNA technology, however adult porina moth species can be visually distinguished. The genus was first identified by Pierre Viette in 1961, who recognised a distinction between the New Zealand members of the genus Oxycanus and those occurring in Australia and New Guinea.
