Oeconesus lobatus is a species of caddisfly belonging to the family Hydrobiosidae. The species was first described by Keith Arthur John Wise in 1958, and is endemic to New Zealand.
The species was identified by Wise in 1958, based on a specimen collected from Raurimu in 1919 by C. E. Clarke.[1] Some sources such as Ward (1999) consider O. lobatus to be a junior synonym of O. maori.[2]
Wise's original text (the type description) reads as follows:
