A total of 20 Odonata species were recorded from 15 water bodies (3 natural water bodies and 12 manmade reservoirs) in a desert landscape west of the Namak Lake in the northwest of the Central Plateau of Iran, from 27 May to 20 June, 2017. The study area included Qom province and the northern part of Esfahan province (34.07 to 35.14 N, 51.33 to 50.89 E). For Qom province, 17 out of 18 species found are new provincial records. In addition Selysiothemis nigra, Orthetrum chrysostigma and Orthetrum taeniolatum are new findings for Esfahan province. The species around the manmade reservoirs are characterized by a broad ecological amplitude ("generalists") while species assemblages of natural water bodies consisted of more sensitive species. In the arid climate of central part of Iran, manmade reservoirs are major habitats for Odonata species. Although these reservoirs have increased the amount of habitat for generalist species, they do not foster sensitive and specialist species. Furthermore, considering the more intense droughts predicted for these areas in the future, and the current scenario of environmental degradation, some sensitive species may be in danger of local extinction.
A record of male and female specimens of Sinolestes editus Needham, 1930 collected in Dak Hro village (14°19'45'' N, 108°24'23'' E, alt. 1,420m a.s.l.), Dak Roong Commune, K’Bang District, Gia Lai Province, Central Highlands of Vietnam is present with a detailed description of the morphology of these two specimens.
More Odonata found at the Cardamonean foothills in Koh Kong Province of Cambodia in 2014-2018
(2018)
Still unpublished data on Odonata of the coastal foothills of the Cardamom Mts. in Koh Kong Province, SW Cambodia obtained in 2014-2018 are provided. Tetrathemis flavescens Kirby, 1889 is for the first time reported for Cambodia and Risiophlebia guentheri Kosterin, 2015 for SW Cambodia. The photographic records from this area of Gynacantha basiguttata Selys, 1882, Gynacantha demeter Ris, 1911, Heliaeschna crassa Krüger, 1899, Amphithemis curvistyla Selys, 1891 and Pornothemis serrata Krüger, 1902 have been confirmed by specimens. The known local faunas of two neighbouring rivulets in Koh Kong Province, rich in Odonata, are updated and summarised.
Records of Odonata from Gunung Melatai, Nanga Gaat and the Kastima Logging area, all in Sarawak’s Kapit Division, are presented. The most notable records are of Matronoides cyaneipennis Förster, 1897 and Heliogomphus blandulus Lieftinck, 1929. A distribution map for Matronoides cyaneipennis and updated distribution maps for three species from the Coeliccia borneensisgroup are given. Tentative identifications to species of previously published records of Idionyx females are given. The genus Heliogomphus in Borneo, Peninsular Malaysia and Singapore is reviewed and a simple one marker molecular analysis is presented for the genus in this region. Based on reexamination of specimens from the genus and the molecular results, an additional member of the genus is reported from Borneo: H. sp. cf olivaceus Lieftinck, 1961. Although both morphological and molecular results remain incomplete, it does appear likely that there is at least one more species of Heliogomphus present in Borneo than has been recognised until now, and that H. borneensis Lieftinck, 1964 may be a junior synonym of H. kelantanensis (Laidlaw, 1902).
Macromidia genialis buusraaensis subspecies nova (Odonata, Synthemisidae s.l.) from eastern Cambodia
(2018)
Macromidia genialis buusraaensis subspecies nova is described from 10 males and 2 females from three localities of Mondulkiri Province, the eastern Cambodia (the type locality: a brook downstream Buu Sraa Waterfall 12°34' N 107°25' E). The new subspecies is close to M. g. shanensis Fraser, 1927 and differs from it by an additional, and the broadest, yellow spot on S7. It is partly syntopic with Macromidia rapida Martin, 1907. A brief overview of the current knowledge of the genus Macromidia Martin, 1907 is provided.
Results of a brief examination of the spring aspect of Odonata at the Abrau Peninsula and some nearby localities on 2127th May 2018 are presented. Lestes dryas and Caliaeschna microstigma are reported for the Peninsula for the first time, revealing the world northernmost record of the latter. Some old data of Odonata at Novorossiysk and some recent erroneous data on the Krasnodarskiy Kray are referenced and discussed. The known Odonata fauna of the Abrau Peninsula reaches 38 species.
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.
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.
