Résumé
We recorded the Australian guava moth for the first time in New Caledonia. Given its biology and recent spread into New Zealand, this moth may be a pest risk for many fruit crops and native plant species if it is proved to have been introduced in New Caledonia. Indeed, this record challenges our capabilities to identify insect interceptions in the context of a high gap of taxonomic knowledge in New Caledonia. It also urges high endemism islands to implement early detection protocols to prevent establishment and spread of new invasive species.

► The Australian guava moth was accidentally detected in New Caledonia. ► The ability to identify insects in a biodiversity hotspot is a challenge. ► Coscinoptycha improbana could be a new pest for New Caledonian fruit crops. ► Early detection protocols must be set up to avoid the spread of invasive species.
