A glance at the Odonata of the Cambodian coastal mountainous regions: end of dry season in 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.
