Updated and annotated review of Tetranychidae occurring in mainland Portugal, the Azores, and Madeira Archipelagos

Data on the diversity, distribution, and main hosts of spider mites (Acari: Tetranychidae) are scarce in Iberian Peninsula, particularly for Portugal, where only 21 species recorded mainland Azores Madeira archipelagos. Moreover, scientific information is mainly available national publications, difficult to access international researchers. In this paper, we review literature dealing with Portugal archipelagos Madeira, compiling synthesizing most relevant their pest potential. Further was obtained by verifying slides acarological collection Instituto Nacional de Investigação Agrária e Veterinária (INIAV), important collection, collected different plant during period 2018-2020. total, found records 28 mite comprising nine Bryobiinae 19 Tetranychinae, including new Stigmaeopsis nanjingensis Eotetranychus tiliarium. Additionally, record a exotic mainland, lewisi, which two localities Algarve District leaves Euphorbia pulcherrima. This first continental Europe an established population outdoor conditions regulated quarantine pest. We also comment presence seven not reported taxonomic databases but already from Portugal: Aplonobia histricina, rubiphilus, Schizonobia sycophanta, Tetranychus kanzawai Tetranycopsis horridus (at level), Oligonychus perseae Panonychus citri (for mainland). New host given Bryobia praetiosa, Petrobia (Tetranychina) harti, S. E. coryli, kanzawai, lintearius, ludeni turkestani.
