Odonata found in mid-summer 2015 and 2016 at the north-westernmost Black Sea Coast of the Caucasus, with the first record of Cordulegaster picta Selys, 1854 in Russian Federation
Abstract: Results are presented of brief odonatological examination of the Black Sea coastal northwesternmost spurs of the Caucasus between Anapa and Gelendzhik (mostly at Kabardinka village), Russia, in late July/early August 2015 and early-mid July 2016. In total, 28 Odonata species were found, including Cordulegaster picta for the first time in Russia. For C. picta and Caliaeschna microstigma, the world’s northernmost records were made. New localities of species rare in this area are reported: one for Coenagrion scitulum and three for Selysiothemis nigra, including their breeding habitat. Numerous migrant individuals of Pantala flavescens were observed in many localities in 2015 but none in 2016. Observations on trophic activity of Aeshna affinis and A. mixta are reported, the former showing predominantly matutinal and vespertinal activity and the latter diurnal activity. Occurrence of the Chalcolestes spp. in the Caucasus is discussed.
Part 2, Oleg E. Kosterin, page 45 - 57:
Calopteryx virgo feminalis subsp. nov., a long known under the same name but hitherto formally nameless subspecies from the Caucasian Black Sea Coast
Abstract: The populations of Calopteryx virgo of the Black Sea Coast of the Caucasus have females with the distal hindwing part darkened and males with the underside of S10 and appendages whitish, They are known for more than a century and deserve a subspecific status but since the name feminalis Bartenev, 1910 proposed to them is unavailable, a new subspecies is formally erected under the same name, Calopteryx virgo feminalis Kosterin subsp. nov., with the following type locality: Russia, Krasnodarskiy Kray, Gelendzhik Municipality, Kabardinka village, the Doob River lowermost reaches, 44°38'26-53'', 37°55'55''-57'58'' E.

A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.

Results are presented of an odonatological survey of 23 localities in Thala Barivat District of Stung Treng Province, northern Cambodia, on July 26 – August 1, 2016. Most localities were situated in areas of open low deciduous dipterocarp forests on gravel soils, some at hillside areas of tall evergreen dipterocarp forest. The great Mekong River right bank was studied within 7 km downstream of its Nimith (Nimet, Khon Thai, Labak Koun, Khone Pha Pheng) Waterfall. In total, 55 species were found, of which 52 identified to species and three to genus. Two species, Gynacantha saltatrix Martin, 1909 and Macrogomphus matsukii Asahina, 1986, were recorded in Cambodia for the first time. Five obligatory lotic species were found at the Mekong River, namely Dysphaea gloriosa, Prodasineura coerulescens, Burmagomphus asahinai, Nychogomphus duaricus and Onychothemis testacea, including tenerals of P. coerulescens and B. asahinai. Most probably these species breed in the Mekong reach which is enriched with oxygen downstream of the great waterfall cascade.

Drepanosticta kosterini sp. nov. (holotype ♂, from Gunung Penrissen, Kuching Division, Sarawak, Malaysian Borneo, deposited in RMNH) is described from both sexes. It is the sister species of D. actaeon Laidlaw, 1934; a fresh description of the male of D. actaeon and the first description of the female are given, along with discussion of variation in this species. Both D. actaeon and D. kosterini are considered to belong to a species group also including D. rufostigma (Selys, 1886) and a preliminary discussion of variation in this species is given, along with illustrations of both sexes. A neighbour joining COI gene tree for D. actaeon and D. kosterini is presented. The relationships of D. actaeon, D. kosterini and D. rufostigma to other members of the Platystictidae are briefly discussed.

Between 2009 and 2016, a total of 174 Odonata species (Tab. 1) have been recorded in the Dehong Dai and Jingpo Autonomous Prefecture, China. 21 of these species are new records for China, and additional 26 taxa have to be described as new to science. Brief comments on selected species refer to morphological characters, distribution and seasonality.

DragonflyIndia Meet 2016
(2017)
101
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.

Palaeosynthemis opaca sp. nov., a new dragonfly from Papua New Guinea (Anisoptera: Synthemistidae)
(2016)
A new species of the synthemistid genus Palaeosynthemis is described from the northern slopes of Papua New Guinea’s central cordillera. It is distinguished from all congeners by having females with large, nearly black patches at the bases of both wings. The male is most similar to P. cervula and P. feronia, but it differs from those species in having superior anal appendages less than three times as long as S10, basally enlarged and otherwise unarmed vs basally not enlarged (feronia) and almost four times as long as S10 and armed (cervula). Characters of the adults (both sexes) are illustrated and the affinities of the species are discussed.

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.

Coeliccia poungyi dasha subsp. nov. (Odonata, Platycnemididae, Calicnemiinae) from eastern Cambodia
(2016)
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.
