... Unfortunately, there is no specimen to check in hand. From Cambodia, the species has been reported by one male collected in Kep (Kosterin 2011); in Thailand is more common in the south of the country (Hämäläinen & Pinratana 1999). Observations. ...
Phnom Kulen is a small and low plateau in the northern Cambodia still partly covered with evergreen forests and isolated from similar habitats by the Cambodian Lowland at least for 60 km. A preliminary checklist of its Odonata is provided, including 97 species. Burmagomphus sp. cf. willamsoni and Macromia callisto are for the first time reported for Cambodia.
... Colors often fade in preserved specimens, and immature individuals of Coeliccia species often display other colors than the adults (Kosterin 2011, Laidlaw 1932, Steinhoff & Uhl 2015. Thus, in their comparison Steinhoff & Do (2013) did not take into consideration that 1) Fraser had described the sides of the thorax as pale blue, 2) that he indicated that S9 was completely pale blue or yellow dorsally, 3) although they called the proximal border of the antehumeral stripe the outer border, this must be the opposite of what Fraser meant. ...
Five new species of Coeliccia (Coeliccia caerulea sp. nov. [holotype: Bao Loc, Lam Dong Prov., appr. 11.449N,107.712E], Coeliccia coronata sp. nov. [holotype: Bao Loc, Lam Dong Prov., appr. 11.726N, 107.713E], Coeliccia curua sp. nov. [holotype: Ba Be National Park, Bac Kan Prov. appr. 22.413N, 105.610E], Coeliccia diomedea sp. nov.

[holotype: Huu Lien Nature Reserve, Lang Son Prov., appr. 21.662N, 106.373E]) are described from Vietnam. The females of C. galbina Wilson & Reels, 2003, C. hayashii Phan & Kompier, 2016 and C. suoitia Dow, 2016 are described. Coeliccia montana Fraser, 1933 is shown to be a junior synonym of C. pyriformis Laidlaw, 1932.
... The Koh Kong, Preah Sihanouk, Kampot and Kep Provinces are abbreviated with two boldface letters KK, PS, Ka and Ke, respectively. To avoid confusion of numerals, localities are also denoted by conventional nicknames (underlined), partly coinciding with those given and used in my odonatological publications (Kosterin, 2010(Kosterin, , 2011(Kosterin, , 2012aKosterin & Chartier, 2017). These nicknames follow the locality ordinal numbers after back slash, both underlined. ...

Results are presented of occasional photographic records of butterflies (Lepidoptera, Papilionoidea) made along with studies on the Odonata fauna in 63 localities of four coastal provinces of SW Cambodia (Koh Kong, Preah Sihanouk, Kampot and Kep) in 2010-2018. In total, 151 identified and 15 provisionally identified species are listed; 39 identified species (Troides helena, Graphium agetes, Prioneris philomone, Abisara echerias, Arhopala abseus, A. aedias, A. aida, A. alitaeus, A. atosia, A. avatha, A. bazaloides, A. elopura, Cigaritis lohita, Sinthusa nasaka, Lampides boeticus, Udara selma, Zizeera karsandra, Danaus affinis, Euploea phaenareta, Parantica agleoides, Cyrestis themire, Euthalia malaccana, E. phemius, Discophora timora, Lethe mekara, Badamia exclamationis, Burara harisa, Odina decorata, Tagiades menaka, Ancistroides nigrita, Gangara lebadea, Halpe zola, Hyrtaotis adrastus, Lotongus calathus, Matapa aria, M. sasivarna, Pirdana hyela, Suastus minutus, Thoressa masoni) and 8 provisionally identified species (Poritia cf. erycinoides, Nacaduba cf. pavana, ?Cephrenes acalle, Erionota cf. torus, Halpe cf. hauxvillei, Notocrypta cf. clavata, Potanthus cf. subochraceus, ?Polytremis lubricans) are for the first time reported for Cambodia. These, as well as some other provisionally identified and unidentified species are illustrated. The only not so expected record is a Sondaic species Arhopala athada.

This variation of the wing coloration is not age dependant as shown in experiments on captive individuals in Cambodia: a discoloured male captured on Bokor Plateau lived in captivity for five days without any change in the wing coloration, while two freshly emerged normal males from Koh Kong Province had already formed distinct wing markings, still quite pale, after just 4-5 hours (Kosterin 2011). ...

Euphaea cyanopogon sp. nov. is described and illustrated from specimens of both sexes collected in the Kampongsaom Peninsula in southern Cambodia and the adjacent Phú Quốc Island in Vietnam, both in the Cardamom ecoregion; the holotype ♂ (at RMNH, Leiden) is from Kbal Chhay Waterfall, Cambodia. The male is characterized by having rather narrow wings without areas of strong pigmentation and a face marked with bright blue. The differences and affinities of the new species with E. pahyapi Hämäläinen, 1985 and some of its other congeners are discussed.
... In Cambodia, this area is divided by Koh Kong, Preah Sihanouk, Kampot and Kep Provinces. Earlier the first author (O.K.) published results of several previous odonatological excursions of the foothills in Koh Kong Pro vince in April (Kosterin 2010) and November/December 2010 (Kosterin 2011), August 2011 (Kosterin 2012), May 2013 (Kosterin 2014a) and April 2015 (Kosterin 2015a). Rich photographic data by the second author (G.C.), who is a permanent resident of Ta tai Commune of Koh Kong Province, recorded more interesting species in the Carda monean foothills (Kosterin et al., 2012; Kosterin & Chartier 2014. ...

... It remains unclear if the blunder of the 'active' C. vittata male was somehow conditioned or it was purely a rare random event. C. vittata is widespread and common in Cambodia while M. falcatum is very local and until now was known from only two locations in Koh Kong Province (Kosterin 2011;Kosterin & Chartier 2017) but hitherto not in Preah Sihanouk Province, where the observation reported here was made. This contradicts the most frequently observed situation when the 'passive' partners in aberrant tandems belong to species abundant in respective localities, hence being most frequent targets for not so selective sexual activity (Corbet 1999). ...
... Based on specimens from south-western Cambodia, Kosterin (2011) asserted that the diagnostic differences in the colouration of the head and thorax of these two species were in fact those of an immature and mature insect, respectively, while the supposed difference in the cerci shape was only a matter of individual variation. He therefore synonymised the two species. ...
... At the time of synonymisation, all existing records of C. kazukoae (including C. megumii) were confined to the Cardamom Mountains in the eastern Thailand and south-western Cambodia and the Sankamphaeng Mountains in eastern Thailand (Hämäläinen & Pinratana 1999;Kosterin 2010Kosterin , 2011.

Coeliccia rolandorum sp. nov. is described from the eastern Cambodia (holotype: Cambodia, Mondulkiri Province, Buu Sraa Waterfall environs, 12°34' N 107°24' E, ~780 m a.s.l., 16 June 2014, RMNH) and southern and central Vietnam. It is related to C. kazukoae, which is known from the Cardamom and Sankamphaeng Mts., and replaces it in eastern Indochina. New distributional data on C. kazukoae are presented and its characters are discussed with respect to their change with age.

In the publication mentioned, the data from the flat marshy coastal areas were provided along with those from foot-Kosterin IDFReport 101 hills of a very different environment, as clad with evergreen forest and rich in streaming water, and in a chronological rather than a systematical order, that made it incon venient to subtract data referring to different habitat types. ...
... The two latter were found just several metres apart at the same ditch of deeper open water; a rare case when these superficially very similar species, seemingly tending to exclude each other (Kosterin 2015a), occurred together. The habitat fitted best for Agriocnemis spp., but net sweeping provided quite a few Mortonagrion falcatum Lieftinck, 1934 of both sexes (4 ♂♂, 4 ♀♀ collected), a species so far reported for Cambodia by only one male collected at Tatai village (Kosterin 2011), but no formally Agriocnemis species (the separation of Mortonagrion from Agriocnemis is artificial for a formal venation character and the former, with some exceptions, seems to be just a clade inside the hence paraphyletic Agriocnemis, see Dow 2011). ...
... The natural condition of the marshy Koh Kong suburbs is described by Kosterin (2010Kosterin ( , 2011Kosterin ( , 2012Kosterin ( , 2014. In general this is alteration of mangrove bays and estuaries and open flat area barely above the sea level with sparse trees (mostly Melaleuca) and bushes (mostly Melastoma), temporary grassy freshwater swamps and ditches and pools, mostly along roads. ...
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.
... Remarks. It is noteworthy that this spe cies was abundant at the 'Loringae brook', and also found at Seima forest, while Rhinagrion viridatum Fraser, 1938, abundant in the Cardamoms (Kosterin 2011(Kosterin , 2012a and also found at Virachey National Park (Kosterin 2014a), was not found at all. Perhaps these species tend to exclude each other. ...
... Surprisingly, no other representatives of the genus were found in the area, e.g. A. pygmaea (Rambur, 1842), which is the most common one at least in E. Thai land and SW Cambodia. Oppositely, A. femina is very common more northerly, in China and Japan, but surpsisingly rare in SW Cambodia (Kosterin 2011). Observations. ...
Results of an odonatological survey of Mondulkiri Province of Cambodia, at the foothills and Central Plateau of the Annamese Mts. in June 8 – June 17, 2014 are presented. Of 106 Odonata species met (46 zygopterans, 60 anisopterans), 97 were identified to previously known named species, of which 15 are reported for the first time for Cambodia, namely Mnais mneme Ris, 1916, Rhinocypha seducta Hämäläinen et Karube, 2001, Philoganga loringae Fraser, 1927, Rhinagrion hainanense Wilson et Reels, 2001, Amphiallagma parvum (Selys, 1876), Ceriagrion chaoi Asahina, 1967, Paracercion malayanum (Selys, 1876), Prodasineura doisuthepensis Hoess, 2007, Protosticta grandis Asahina, 1985, Tetracanthagyna waterhousei McLachlan, 1898, Gomphidia kruegeri Martin, 1904, Heliogomphus chaoi Karube, 2004, Leptogomphus baolocensis Karube, 2001, Microgomphus jurzitzai Karube, 2000, Onychothemis culminicola Förster, 1904, and two species for which the specimens collected on this trip were described as new subspecies: Indolestes gracilis expressior Kosterin, 2015, Coeliccia poungyi dasha Kosterin, 2016. Five species collected on this trip have been described elsewhere as new to science, namely Onychargia priydak Kosterin, 2015, Prodasineura hoffmanni Kosterin, 2015, Asiagomphus reinhardti Kosterin et Yokoi, 2016, Euthygomphus schorri Kosterin, 2016 and Risiophlebia guentheri Kosterin, 2015. So the total number of the first country records of named species made on this trip is 22. Still four species found may be undescribed. The number of named species recorded in Cambodia has reached 178. Remarks on taxonomy and variation of Euphaea masoni Selys, 1879, E. ochracea Selys, 1859, Aciagrion approximans (Selys, 1876), and Lamelligomphus castor Lieftinck, 1941 are provided. Characters of mature males of R. seducta are updated. Notes on habitats and habits of some species are provided. Onychothemis culminicola and O. testacea Laidlaw, 1902 seem to exclude each other at rivers, the former occupying smaller and more elevated ones; a putative hybrid male was observed. General notes on the area and field impressions are briefly outlined.
... However, in the current sense the genus is paraphyletic in molecularly re constructed phylogenetic trees (Dijkstra et al. 2014) and most probably will be soon split into smaller genera, or absorb the genus Indocnemis Laidlaw, 1917 (with two species, one of which occurring in all the three above mentioned countries and the other in Vietnam). The Odonata fauna of Cambodia, which is bordered by Vietnam, Laos and Thailand, is still insufficiently studied, so only two Coeliccia species have so far Kosterin IDFReport 97 been identified from this country, Coeliccia kazukoae Asahina, 1984 (Kosterin 2010(Kosterin , 2011 and C. yamasakii Asahina, 1984 (Kosterin & Holden 2011). A possibly undescribed species related to C. kazukoae has also been reported (Roland et al. 2011). ...
Coeliccia poungyi dasha is described from the Annamense Mts. in the eastern Cambodia (holotype: Cambodia, Mondulkiri Province, a brook, a left tributary of the main river downstream Buu Sraa Waterfall, 12°34'0119''
N 107°24'50''25' 03'' E, 416490 m a.s., 15.06. 2014, RMNH). The new subspecies differs from the nominotypical one in coloration of the mesepisternum in males and end of the abdomen in both sexes, as well as in the length of the terminal lobe of the genital ligula.
