A glance at the Odonata of the Cambodian coastal mountainous regions : end of dry season in 2010
(2010)
During a visit to the coastal regions of Cambodia within the Provinces of Koh Kong, Kampong Saom, Kampot and Kep within April 12-23, 2010, 59 species of Odonata were found. Of these, 51 were identified, 2 preliminarily identified (1 by exuviae, 1 to a known species with the valid name unresolved), 1 dubious (Aciagrion cf. pallidum), 3 not identified (just visual observations) and 2 seemingly undescribed, namely Burmagomphus sp. and Microgomphus sp. Fourteen species were recorded for the first time for this country, namely Neurobasis chinensis, Dysphaea gloriosa, Euphaea masoni, Onychargia atrocyana, Copera marginipes, Copera vittata, Prodasineura autumnalis Prodasineura verticalis sensu Asahina, 1983, Lathrecista asiatica, Orthetrum chrysis, Rhyothemis obsolescens, Tramea transmarina euryale, Zygonyx iris malayana, Zyxomma petiolatum; taking the current checklist for Cambodia up to 83 species. Some features of the collected specimens relevant to their taxonomy are discussed. Brief field notes are provided and Odonata records enumerated. The habitats and community of Odonata at the Cardamon Mts. foothills at the end of dry season are discussed.
The ecological and faunistic research of Odonata in Ukraine has been based on three main pillars. The first are investigations of species composition, habitat preferences, trophic connections, parasites and predators, behaviour patterns, and morphological and physiological peculiarities of dragonflies by expert-odonatologists. The second pillar is the collection and identification of adults for the survey of animals from different regions, especially rare and endangered species for the Red Lists and Red Data Book. Thirdly, there is the study of Odonata larvae as components of freshwater ecosystems, particularly as food of fish.
Some present Ukrainian regions belonged to Poland, Hungary, Slovakia and Romania before 1939-1945. Odonatological investigations were held up during the Second World War and the 12 years of post-war rebuilding.
The first data on Ukrainian Odonata were published in the second part of the 19th century (Belke, 1859, 1866). Since then, several Ukrainian, Russian, Polish, Hungarian and Romanian scientists have made great contributions to the investigation of the odonate fauna and ecology. One of the most famous odonatologists, J. Dziêdzielewicz, worked in the western Ukraine from the end of the 19th to the early 20th century. At the same time G. Artobolevs’ky investigated the northern and central parts of Ukraine and the Crimea peninsula. A. Brauner and A. Bartenev carried out research in the southern Ukraine and Crimea.
R. Pavlyuk continued research in the western region of Ukraine. He carried out faunistic, ecological and parasitological investigations. A. Oliger studied faunistic and ecological aspects of dragonflies in the easternmost part of the Ukraine (Donets’k region). Recently, S. Gorb published many papers devoted to the functional morphology of dragonflies. He also provided a study of the species composition and ecological peculiarities of Odonata in northern Ukraine and a catalogue of the Ukrainian species. Today, several odonatologists are actively involved in odonatological research in Ukraine. N. Mathuskina works on the functional morphology of the ovipositor and dragonfly behaviour, L. Khrokalo on faunistics and ecology in the northeastern Ukraine and on aspects of nature conservation, O. Dyatlova on the faunistics in the southwest of the country and some aspects of morphology and behaviour. A. Martynov studies the faunistics in the eastern part of Ukraine.
65 species of Odonata are recorded from Mulanje and its slopes. Only eight species dominate on the high plateau. Among them are two relict species of conservation concern: The endemic Oreocnemis phoenix (monotypic genus) and the restricted-range species Chlorolestes elegans. The absence of mountain marsh specialists on the plateau is noteworthy. Mulanje’s valleys, of which Likabula and Ruo are best known, have a rich dragonfly fauna. The Eastern Arc relict Nepogomphoides stuhlmanni is common here.
During summer field work in 2005 and 2009 data on the distribution of dragonflies were obtained on the territory of Moldova. In August 2005, 9 species were recorded for the middle part of the Dniester river (surroundings of Sakharna). Between 28 June and 4 July 2009 dragonflies were studied in almost all parts of the country - 25 species were observed. Four species (Lestes macrostigma, Coenagrion ornatum, Coenagrion scitulum, Orthetrum brunneum) were recorded for the first time in Moldova. For many species the knowledge of their Moldovan distribution was improved. The habitats of every species were described, illustrated and preliminary maps of species distribution were prepared. Literature data were also analysed and a check list of Moldovan dragonflies was created containing 37 species. The presence of several species (including Nehalennia speciosa) in Moldova needs confirmation.
Polillo is a small group of island (27 islands in total) east of central Luzon (Figure 1). It is made up of four main island viz. Polillo I, Patnanungan I, Jomalig I and Palasan I and several islets. This island group has relatively flat to gentle sloping terrain and the highest point is only 300 m asl (Mt. Maluhod) in Polillo Island (ca 700 km²) which is the largest in the group and the third largest island in greater Luzon biogeographic region.
The paper compiles records from four excursions to study the Odonata fauna of southern Guizhou, China. Between 2007 and 2010 in Xiaoqikong Park and Maolan National Nature Reserve, 104 taxa have been recorded. Some interesting species are discussed, compared with sibling taxa, and information on habitats and habits is given.
Records of Odonata collected from Gunung Pueh and the surrounding area, in west Sarawak, in October 2012, are presented. 67 species were collected; two species were recorded in Borneo for the first time: Libellago stigmatizans and Copera ciliata. Othernotable records include Podolestes chrysopus, Telosticta gading, Agriocnemis mini-ma and Pseudagrion coomansi. Some additional, previously unpublished, records from the most western part of Sarawak are included in two appendices.
