SUMMARY:

The order Odonata comprises a group of aquatic insects commonly known as dragonflies and damselflies. Brazil registers over 860 species of odonates, representing the highest diversity in the Neotropical region. However, knowledge about the group is assimetrical across the country. Taxonomic and distribution data about these organismis in the Northeast region remains quite limited, resulting in gaps in our basic understanding of these organisms. To date, no study has conducted a comprehensive survey about odonate species in the state of Rio Grande do Norte (RN), with only isolated records of four species reported in its territory. This study aimed to compile the first species list for the order Odonata in RN and provide information on their known distribution of these insects in the state. Addtionaly, an electronic identification key was developed for part of the recorded species using the Lucid software. The data used to create the list were obtained through the analysis of 2,728 specimens preserved in the Adalberto Antônio Varela-Freire Entomological Collection (UFRN – CENT) and literature records. Forty species were recorded in the state territory, distributed among 6 families and 28 genera. Of these, 30 species are new records for the state, while 10 had ben previously documented in publications. We also verified the existence of occurrence records for 34 municipalities in the state, with 25 species recorded in Serra Negra do Norte, the municipality with the highest number of species. The results reveal a previously unknown diversity for the state, which is consistent with the species lists of neighboring states. Furthermore, they highlight the need to expand sampling efforts, especially in the central, western, and agreste mesoregions of the state, and emphasize the importance of conservation areas and the involvement of academic and student collaborators.
