Titanomis is a genus of moths containing a single species, Titanomis sisyrota, also known as the frosted phoenix. Taxonomists are currently unable to place this moth within an existing superfamily. The species is currently regarded as endemic to New Zealand, and classified as "Data Deficient" by the Department of Conservation. Described as "New Zealand's most enigmatic moth", only ten specimens have been collected, none since 1959. After 65 years without a sighting, a living individual was observed in March 2024 by a Swedish tourist.
