We present an annotated list of 28 Odonata species (19 Anisoptera, 9 Zygoptera) from Timor Island based on 464 records via photographs and 56 specimens held in collections at the Museum and Art Gallery of the Northern Territory, Darwin, Australia and the Museum Wiesbaden, Germany. Additionally 43 records of eight species (7 Anisoptera, 1 Zygoptera) from Rote Island and one record from Romang were reported. Most Timorese records are from Oecusse Special Administrative Region/Timor-Leste, a region which to date was "terra incognita". Further records from Timor-Leste are predominantly from Lautem Municipality and Baucau Municipality as well as from the Indonesian Kupang Regency. Four species are new records for Timor Island increasing the checklist to 40 species: Brachythemis contaminata (Fabricius, 1793), Tholymis tillarga (Fabricius, 1798), Gynacantha sp. cf. dobsoni Fraser, 1951and Ischnura aurora (Brauer, 1865). We provide the first photographs of live Nososticta impercepta Seehausen & Theischinger, 2017 as well as some descriptions of habitats in Oecusse. At Rote Island five species were reported for the first time as well: Brachythemis contaminata, Crocothemis servilia (Drury, 1773), Rhyothemis phyllis (Sulzer, 1776), Macrodiplax cora (Brauer, 1867) and Potamarcha congener (Rambur, 1842). The record of Orthetrum testaceum (Burmeister, 1839) from Romang Island appears to be the first Odonata documented from this island. The status of Rhyothemis phyllis is discussed with regard to the ssp. ixias Lieftinck, 1953 from the islands of Sumba and Flores. We provide distribution maps of each species as well as suggestions for targeted field research in the future. All historical records of Nososticta selysii (Förster, 1896) from Timor are now assigned to Nososticta impercepta.

The Odonata found during work on the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Project in Riau Province, Sumatra, Indonesia are reported. Prior to the BEFTA project we are only aware of published records of 37 species of Odonata from Riau Province (these are listed in an appendix). Seventy five species have been recorded during the BEFTA project, including five that have not (Archibasis incisura, Archibasis rebeccae and Pseudagrion williamsoni), or not definitely (Argiocnemis species and Mortonagrion species cf aborense), been recorded in Sumatra before. Macromia dione is recorded for the first time since its description. The number of species now known from Riau Province is 88; 51 of these are reported from the province for the first time here.
