In 2014, 56 localities in four provinces of Lesser Himalaya in Pakistan were studied. A total of 28 species have been recorded. A female of the data deficient, threatened species Coeliccia vacca was recorded from Charhaan. The record of Drepanosticta carmichaeli is a new addition to the list of Odonata of Pakistan, and expand the range of this species further to the west. The taxonomical status of Ischnura aurora aurora – considered common in Pakistan, following baseline literature of Fraser (1933) – now turns out to be Ischnura aurora rubilio.

During three field trips in 2009-2010 to Xuan Son National Park in Phu Tho province in northern Vietnam, a total of 13 species of damselflies of the superfamily Calo-pterygoidea were recorded. These records are documented here with field photo-graphs of living damselflies. Observations on their biology and behaviour are also noted. Three of the species are reported from Vietnam for the first time: Rhinocypha arguta, an undescribed Matrona species and Vestalaria miao. The last species was first found in Huu Lien Nature Reserve in Lang Son province in June 2008.

Hauptziel der Untersuchung war die Erhebung von Daten zur Verbreitung von S. arcti-cain den 17 ausgewählten Moorgebieten entlang der polnischen Ostseeküste und in der Pommerschen Seenplatte. Im Rahmen dieser Studie in odonatologisch bisher wenig bearbeiteten Gebieten wurden drei neue Fundorte von S.arctica gefunden, in denen diese Art kleine, aber beständige Populationen bildet. Zwei dieser Gebiete liegen weit von den bisher bekannten Vorkommen entfernt. Für zukünftige Arbeiten ist es wichtig zu untersuchen, ob diese Fundorte populationsökologisch isoliert sind oder ob S. arctica auch in den geographisch dazwischen liegenden Biotopen vorkommt. Ein weiteres Ziel des Vorhabens war eine Verbesserung des allgemeinen Wissens zur regionalen Libellenverbreitung. Die Studie dokumentiert für diese odonatologisch bisher nicht bearbeiteten Gebiete eine hohe Libellendiversität. Hinzu kommt, dass in 15der 17 untersuchten Gebiete mindestens eine rechtlich geschützte Libellenart vorkommt. Dies lässt vermuten, dass die Renaturierungsmaßnahmen eine positive Auswirkung für die seltenen und lebensraumspezialisierten Libellenarten haben. Diese Studie stellt somit eine Grundlage für zukünftige Analysen zur Bewertung des Erfolges der aktiven Moorschutzmaßnahmen auf Basis der Libellen dar.

Sympetrum fonscolombii is for the first time reported for Tuva (Tyva Republic, Russia), as found in the UbsuNur Depression. New data are provided on Odonata of the Turan or TuranUyuk Depression of Tuva, including the first record of Somatochlora exuberata in Tuva beyond the Todzha Depression and Coenagrion armatum, C. ecornutum, Aeshna juncea, A. grandis, Somatochlora graeseri and Libellula quadrimaculata for the first time reported for the Turan Depression. New distributional data and comments on Ophiogomphus spinicornis Selys, 1878 are added. Somatochlora alpestris found at Lake Oyskoe is for the first time reported for the southern Krasnoyarskiy Kray.

Results are presented of a brief odonatological examination of the Abrau and Taman' Peninsulas at the northwesternmost Caucasian Black Sea coast in Krasnodarskiy Kray, Russia, on July 2026, 2017. Twenty three species have been observed at the former peninsula and five at the latter. The Odonata records at the Abrau Peninsula are summarised, to include 34 species.

New data on Odonata of the Preah Sihanouk Province of Cambodia obtained in March 2017 and November 2018 are presented. The presence of Onychargia atrocyana Selys, 1865 in Cambodia is confirmed. Twentyone species are added to the known fauna of the Kbal Chhay Waterfall environs, 19 species to that of Ream Peninsula and 4 to that of Koh Rong Island. The total number of species registered for Kampong Saom Peninsula amounts to 74. The presented data are rather of historical importance since most of the remaining forest has been quickly and irreversibly logged a few months ago. The validity of Gynacantha demeter Ris, 1911 as a species distinct from G. dohrnii Krüger, 1899 is doubted.

The Odonata fauna of flat marshy areas of the Gulf of Siam coast in Koh Kong Province of Cambodia, containing 55 species, is considered. The published data of 2010- 2013 and new data of 2014 and 2016 on the surroundings of Koh Kong town are compiled and the first data on the area of large swampy Melaleuca forests at Andoung Tuek village are presented as well as some occasional photographic records. Gynacantha bayadera, Lyriothemis mortoni and Pornothemis serrata were for the first time recorded for Cambodia. Mortonagrion falcatum was found unexpectedly abundant at Andoung Tuek.

Untangling some taxonomic riddles on damselfly genera (Zygoptera) from the neotropical region
(2007)
Examination of type material deposited in the IRSNB (Royal Belgian Institute of Natural Sciences, Brussels, Belgium) and in the BMNH (British Museum of Natural History, London, Great Britain) allowed us to solve taxonomic riddles regarding several damselfly (Zygoptera) genera from the neotropical region. We provide notes on the status of several types, and introduce the following new synonymies: Argia huallaga Fraser, 1946 = A. adamsi Calvert, 1902; Argia makoka Fraser, 1946 = A. kokama Fraser, 1946; Argia mollusca Fraser, 1946 = A. collata Selys, 1865; Argia trifoliata Fraser, 1946 = A. variegata Förster, 1914; Argia umbriaca Fraser, 1946 = A. indicatrix Calvert, 1902; Amphiagrion amphion Selys, 1876 = Ischnura verticalis (Say, 1840); a new combination: Oxyagrion cardinalis Fraser, 1946 to Leptobasis cardinalis (Fraser, 1946); and three lectotype designations (for Acanthagrion gracile race? lancea Selys, 1876, Acanthagrion trimaculatum Selys, 1876, and Leptagrion flammeum Selys, 1876).

Two new subspecies of Hemicordulia tenera Lieftinck, 1930 (Corduliidae) from Cambodia and Thailand
(2015)
Hemicordulia tenera donnellyi ssp. nov. (holotype ♂: Chieng Mai Prov., Kunklang: highway 1009, Restaurant; 16°32.0’ N 98°31.3’ E, 1000 m, 22 v 1996, FSCA) and H. t. vikhrevi ssp. nov. (holotype ♂: Cambodia, Koh Kong Province, ~13 km ENE of Koh Kong, ‘Hemicordulia brook’, 11°39’55’’ N, 103°05’34’’ E, 315 m, 04 xii 2010, RMNH) are described from North Thailand and South-West Cambodia, respectively. The nominotypical H. tenera tenera Lieftinck, 1930 is distributed in the Malay Peninsula, Borneo, Java and Sumatra. Although these three subspecies are genetically very close, they are distinguishable by the relative length and shape of the caudal appendages.
