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.

As a result of increased interest in dragonflies and close cooperation between odonatologists on the Balkan Peninsula, the Balkan Odonatological Meeting (BOOM) has been established in 2011. This report presents the results of the field trip during 4th Balkan Odonatological Meeting that was held in Bosnia and Herzegovina from 1st to 8th August 2014. With 69 surveyed localities and 496 records of 47 species, this was the most successful BOOM until now. The noteworthy results are records of several nationally rare species: Chalcolestes viridis, Coenagrion scitulum, Erythromma najas and Ceriagrion tenellum, and new populations of Cordulegaster heros, a species mentioned in the Annexes of the EU Habitats Directive. The distribution of Chalcolestes spp. in Bosnia and Herzegovina is also presented and discussed.

Distribution data of dragonflies and damselflies from western Bhutan collected during a trip from 10 October 2015 to 22 October 2015 are presented. In total 53 species were recorded of which eleven are new to the country (Aciagrion pallidum, Anisopleura lestoides, Megalestes irma, Gynacantha incisura, Gynacantha khasiaca, Gynacanthaeschna sikkima, Lamelligomphus risi, Somatochlora daviesi, Crocothemis erythraea, Sympetrum fonscolombii, Tholymis tillarga). Another three species, one Megalestes and two Cephalaeschna, were not identified to species level but are also addition to the list of species recorded from Bhutan.

Specimens of Neurothemis disparilis Kirby, 1889, N. fluctuans (Fabricius, 1793), N. fulvia (Drury, 1773), N. ramburii (Brauer, 1866), N. stigmatizans (Fabricius, 1775) and N. terminata Ris, 1911, including their subspecies, were studied with the main focus on the morphology of the vesica spermalis, wing maculation, wing venation, abdominal markings and vulvar scales. The results were compared with species descriptions and directly with type specimens where possible. The vesica spermalis, especially the medial process, is useful at least in separating species groups and supports the traditional differentiation methods using wing maculation and venation. The use of other characters in accessing specific status, coupled with known distribution patterns, is discussed. The following taxonomic changes are proposed: Neurothemis manadensis (Boisduval, 1835) stat. nov., Neurothemis papuensis (Lieftinck, 1942) stat. nov. and Neurothemis taiwanensis sp. nov. is described (27.5.1998, Kenting, Pingtung County/Taiwan, L. M. Juang leg.; holotype is deposited at Taiwan Forestry Research Institute, Taipeh, Taiwan). The type of Polyneura palliata Rambur, 1842 was rediscovered at MNHN and designated as lectotype; a lectotype for Neurothemis nicobarica Brauer, 1867 housed at NHMW is designated. The holotype of Neurothemis incerta Brauer, 1867 was rediscovered and synonymized with N. ramburii.

A catalogue of 1290 persons commemorated in the scientific names of extant dragonflies (Odonata) is presented together with brief biographical information for each entry, typically the full name and year of birth and death (in case of a deceased person). For each individual a list is given of all available species, subspecies, genus or subgenus names erected in his or her honour. In total 2021 available names which qualify as eponyms are listed. These comprise 1966 species-group and 55 genus-group names including synonyms and homonyms. It is calculated that of the ca 8550 available species-group names in extant Odonata, ca 23 % are eponyms. Of the 1065 new species-group names introduced between 1 January 1995 and 31 December 2015, 435 (40.8 %) are eponyms.

New faunistic data is provided on the Odonata inhabiting the three main islands within the Samoan archipelago, namely Savai’i, Upolu and Tutuila as well as the smaller islands of Aunu’u and the Manu’a group. The specimens collected or observed in the field were compared to samples from other nearby Pacific island groups such as Fiji and Tonga. This study makes important contributions towards resolving taxonomic issues regarding the Ischnura species described as endemic to Samoa and their relations to other Coenagrionidae genera. New diagnostic features for distinguishing between females of the endemic genera Amorphostigma and Pacificagrion, subspecies separation in the Pacific Tramea transmarina and distinguishing between Samoan Hemicordulia species are suggested. Anaciaeschna melanostoma is proposed as junior synonym of A. jaspidea. A possible new subspecies of Lathrecista asiatica, confined to the Samoan archipelago, is discussed. The validity of Agriocnemis interrupta as a separate species from A. exsudans is questioned. Pacific Pseudagrion is believed to be represented within the region by one species only, with separate subspecies in Fiji, Tonga and Samoa, although more specimens from Fiji are required to resolve this issue.

Two new species of damselflies are described from central Halmahera in North Maluku Province, Indonesia. They are Drepanosticta pararudicula sp. nov. (Holotype MZB. ODON. 19257) and Nososticta halmahera sp. nov. (Holotype MZB. ODON. 19265). The two species are most similar to the Moluccan taxa D. rudicula and N. moluccensis respectively and their descriptions bring the total number of Drepanosticta species known from Halmahera to five and of Nososticta to two.

The Cardamom foothills were re-assessed for Odonata in the late dry season of 2015 within E Thailand and SW Cambodia. In the narrow coastal strip of Trat Province of Thailand bordering to Cambodia, 44 species (1 unidentified) were recorded, of which 15, namely Agriocnemis nana, Archibasis viola, Ischnura senegalensis, Pseudagrion microcephalum, P. williamsoni, Acisoma panorpoides, Brachythemis contaminata, Brachydiplax farinosa, Hydrobasileus croceus, Macrodiplax cora, Rhyothemis plutonia, R. variegata, Tholymis tillarga and Trithemis pallidinervis were recorded for Trat Province for the first time. That increased the number of species recorded for the province to 61. Preliminary checklists of Odonata of Ream Peninsula (that is of Ream National Park) and of Koh Rong Island were complied, mostly on the data of this trip, to count 45 species (2 unidentified) and 17 species, respectively. As many as 36 species were recorded at the village of O’Som, Pursat Province. Copera marginipes is added to species recorded from Bokor Hill Station. Superficially similar males of Pseudagrion australasiae and P. microcephalum were observed in the same locality in Ream National Park.

This article contains new faunistic data on 53 Odonata species based on material collected by the authors in Azerbaijan between 2013-2014 and added by revising an old collection made by A.V. Bogachev in the 1930-1940s. Of these, 13 species are new for the country: Lestes dryas, L. sponsa, L. virens, Coenagrion hastulatum, C. lunulatum, C. ornatum, C. pulchellum, Aeshna affinis, Brachytron pratense, Cordulegaster picta, Somatochlora flavomaculata, Sympetrum flaveolum, S. vulgatum. The new locality of Cordulegaster picta is the easternmost for the species. Two new populations of a very rare species Cordulegaster vanbrinkae (discovered in the country in 2011) are found. Somatochlora flavomaculata and Brachytron pratense are generally very rare in the entire Caucasus. Pantala flavescens has been rediscovered in the country 100 years after the first record. A large population of Caliaeschna microstigma, a species very rare in Azerbaijan, has been found in the northern part of the country; it represents a peculiar dark morph whose features are described in detail. Particulary discussed are the variability of Coenagrion puella-complex in Azerbaijan and diagnostic features of two other Coenagrion species closely related to each other, C. ornatum and C. vanbrinkae.

On the Odonata of North Kazakhstan Province. I. First data on Petropavlovsk
Abstract: The fauna of Odonata of the environs of Petropavlovsk, North Kazakhstan, was for the first time examined on two short trips in late June and mid August 2015. Thirty five species were revealed. Coenagrion ecornutum was recorded in Kazakhstan for the first time, Gomphus vulgatissimus the second time and Stylurus flavipes the third time. Range expansion of C. ecornutum is discussed. Comparison is attempted of the known local Odonata faunas of the environs of Petropavlovsk, Omsk and Novosibirsk cities residing at the same latitude in the West Siberian Lowland. The Petropavlovsk fauna is very close to that of Omsk. The earlier published Kazakh records of G. vulgatissimus and S. flavipes are clarified and corrected. Breeding of Aeshna viridis in Ishim River (lacking water soldier) is supposed.

Odonata registered on a short excursion to Kyshtovka District, Novosibirsk Province, Russia
Abstract: During a fourday trip to Kyshotovka District, the most northwestern district of Novosibirsk Province, 21 species of Odonata were recorded. Two significant findings were made: that of Coenagrion ecornutum is most northern in West Siberia, and that of Lestes macrostigma is perhaps the northernmost in its range. The latter species was found over small, shallow, freshwater pools along a roadside. The diversity of this species’ habitats in Siberia in comparison to its uniform habitats at brackish water in Western Europe is discussed.

Two new Cordulegaster species are described and illustrated by drawings, photographs and SEM images. The first one, C. plagionyx sp. nov., was discovered in NW Azerbaijan in a low-mountain forest landscape; the second, C. nachitschevanica sp. nov., occurs in the subalpine zone of Nakhichevan AR, south of the main territory of Azerbaijan. Both new taxa look generally similar to C. insignis Schneider, 1845; however, each of them reveals unique features and distinctive combinations of characters that set them apart from other species of the genus. Both new species exhibits new types of sex dimorphism previously unknown in Cordulegaster. Some traits related to the structure of male appendages and important details of colouration prevent both C. plagionyx sp. nov. and C. nachitschevanica sp. nov., from being reliably classified under any of two widely accepted groups of species within the genus Cordulegaster: the boltonii-group and the bidentata-group.
84
Records of Odonata from two areas in the upper Baram area in Sarawak's Miri Division are presented. Sixty five species are recorded from the Sungai Sii area and sixty three from the Ulu Moh area. Notable records include Telosticta ulubaram, Coeliccia southwelli, Leptogomphus new species, Macromia corycia and Tramea cf. virginia. Rhyothemis regia is recorded from Sarawak for the first time.

Taxonomical notes on Indolestes Fraser, 1922 (Lestidae, Zygoptera). 1. Indolestes gracilis expressior ssp. nov. from eastern Cambodia
Abstract: Indolestes gracilis expressior ssp. nov. is described by a male from Cambodia, Mondulkiri Province, the river upstream of Buu Sraa Waterfall 12°34’ N 107°25’ E. Another male presumably belonging to this subspecies was illustrated from southern Laos in literature. The new subspecies is characterised by more inflated apical part of the cercus than in earlier known subspecies and is thought to range in plateaux of eastern Cambodia ?and southern Laos, although very rare.

Taxonomical notes on Indolestes Fraser, 1922 (Lestidae, Zygoptera). 2. Indolestes birmanus (Selys, 1891) is bona species
Abstract: The holotype of Lestes birmana Selys, 1891 (currently Indolestes birmanus (Selys, 1891)), housed in Museo Civico di Storia Naturale di Genova, is examined and depicted
for the first time. Its cerci are not attenuated apically, hence this taxon cannot be a subspecies of Indolestes gracilis (Hagen in Selys, 1862).

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.

A catalogue of 1257 persons commemorated in the scientific names of extant dragonflies (Odonata) is presented together with brief personal information on each entry, typically the full name and year of birth and death (in case of a deceased person). Each individual has a list of the available species, subspecies, genus or subgenus names erected in his or her honour. A total of 1928 available eponymous species-group and 54 genus-group names are listed. These figures include also synonyms and homonyms. It was calculated that of the ca 8400 available species-group names in extant Odonata, ca 23 % are eponyms. Of the 933 new species-group names introduced from 1 January 1995 to 10 March 2015, as many as 42.9 % are eponyms.

Records of larval rearing in the Gunung Mulu National Park, Sarawak, Malaysia carried out in 2014 are presented. In total, larvae of 27 species were collected. Larvae of eleven species (22 individuals) were successfully reared out, one individual is currently still being reared. An additional three species were collected right after emergence, with the adult still sitting on its exuvia. Most notable are the samples of Orthetrum borneense, Leptogomphus cf. pendleburyi, Coeliccia cf. nemoricola 1, Coeliccia cf. nemoricola 2, Heliocypha biseriata and Elattoneura analis whose final instar larvae are undescribed.
