Using integrative taxonomy to delimit species in the plant bug genus Pseudoloxops (Hemiptera: Miridae) in French Polynesia.

This article focuses on the integrative taxonomic revision of the plant bug genus *Pseudoloxops* (Kirkaldy 1905) in the Austral and Society archipelagos of French Polynesia. Using a unified species concept and multiple lines of evidence—including molecular phylogenetics (CO1, 16S, 28S genes), geometric morphometrics of male genitalia, genetic distances, plant associations, and geographic distributions—the study recognizes 20 endemic species, describing 17 as new to science and redescribing 3 previously known species while synonymizing others. The research highlights notable color polymorphism and host associations, including several species specialized on ferns, and reveals French Polynesia as a significant hotspot for *Pseudoloxops* diversity, with many species exhibiting single-island endemism. The findings underscore the value of integrative taxonomy in resolving species boundaries in complex insect radiations and contribute to biodiversity knowledge critical for conservation in these island ecosystems.
