A contribution to the Odonata fauna of Moala Island, Fiji. Part I: erection of three new species in genera Nesobasis Selys, 1891 and Nikoulabasis Ferguson et al., 2023 (Odonata: Coenagrionidae)

This study records the first members of Nesobasis Selys, 1891 and Nikoulabasis Ferguson et al., 2023 from Moala Island, Fiji. Three new species were erected for the following endemics: Nesobasis delai, sp. nov. (holotype male, headwater system, a tributary of Waitabu Lake), Nesobasis malokuensium, sp. nov.

(holotype male, tributary of Wailevu Creek above Maloku village) and Nikoulabasis pauta, sp. nov. (holotype female, section of Wailevu creek about 500 m above Maloku village up to the Savukaratu waterfall). Three discussion points are outlined for future studies: phenology, female bias sexual ratio and biogeography.
