A revised and updated Odonata checklist of Samoa (Insecta: Odonata)

Odonata records of the Samoan Archipelago are updated and an updated checklist provided. It is part of an ongoing assessment of the fauna, taxonomy and distribution of the Pacific island dragonflies. The checklist follows recent reviews published/prepared about the Solomon Islands, New Caledonia, Fiji and Kingdom of Tonga. This study draws on recent dragonfly records following general insect surveys spanning 2008-2012 funded by Critical Ecosystem Partnership Fund (CEPF) via Conservation International (CI) to the authors and to Secretariat Pacific Regional Environment Program (SPREP) and also by funding from Japan International Cooperation Agency (JICA). Other unpublished data from Samoan Archipelago and Niue are included as well. All, but one, of the newly collected Odonata species are widespread within the Pacific region. Hemicordulia cupricolor is the only species from the recent collections which is endemic to Samoa, previously reported for Savai’i and Upolu Islands. It has never been confirmed since its original description in 1927. The new study shows the species as an inhabitant of high altitude zones of Savai’i. It is recommended inland areas of Savai’i and other islands within the Samoan Archipelago should be targeted in further field studies.
