In July 2005, Rafal Bernard requested Oleg Kosterin to collect some samples of Nehalennia speciosa from West Siberia for a DNA analysis. Oleg replied that so far he had only seen one individual of this species 25 years ago, but asked in which habitats it should be sought for exactly. Rafal sent him a draft of his paper (Bernard & Wildermuth, 2005) devoted to this subject. Having read it, Oleg came to the conclusion that this habitat (shallow water with Sphagnum and Carex limosa or C. lasiocarpa) might occupy the largest area in the world just in the boggy West Siberian Plain. Personal consultation with the geobotanist Dr. Nikolai Lashchinskii confirmed this notion. Then an almost automatic supposition followed that this area may serve as the main reservoir of N. speciosa, considered a local and endangered species in Western and Central Europe. At the same time, the existing records of N. speciosa from West Siberia were remarkably scarce. It was known from the Khanty-Mansi Autonomous Region (basins of the Tura and Konda Rivers), a small number of records from North Altai and adjacent areas north of it, a record from the steppe zone of Novosibirsk Province (Karasuk), a record in the basin of the Tuba River (Krasnoyarskii Krai), and a dubious old record from Omsk (see the map in Belyshev (1973) and a review in Bernard & Wildermuth (2005)). There was no record from the boggy Irtysh-Ob’ interfluve, where we would expect the species to flourish. This could be explained by the lack of attention by odonatologists to that interesting area. In these circumstances, the project of a special expedition(-s) was put forward, aimed to check the presence, pattern of distribution, abundance and habitat preferences of N. speciosa in these areas. For a decisive expedition we chose the Vasyugan Bog, the largest bog in the world, more precisely its north-eastern margin where we could find a good base in Plotnikovo village, Bakchar District, Tomsk Province.

In 2007, a project named Adriatic Montenegro 2007 was initiated and realised under the protection of IDF. Stimulated by the suggestion of Vincent Kalkman from the European Invertebrate Survey, The Netherlands, distribution data for the Odonata of Adriatic Montenegro were collected and used to create distribution maps. These data and maps should then be used in the evaluation of conservation measures for individual odonate species as well as for the IUCN Red List of the Mediterranean countries (organized by the IUCN Centre for Mediterranean Cooperation) and the Project on an atlas of European dragonflies (a co-operation of all European countries organised by the European Invertebrate Survey, The Netherlands).
20
A list of 60 Odonata species and their distribution across 109 localities on the Crimean Peninsula is provided. The study is based on a literature review and a field survey between 1999 and 2008. Erythromma lindenii and Epitheca bimaculata are here recorded for the first time from Crimea. Diagnostic morphological characters of Calopteryx splendens taurica and Orthetrum coerulecens anceps are briefly described. Discriptions of typical Crimean habitats of dragonflies are also presented. The necessity of the protection of Crimean freshwater habitats is discussed.
21
The project Macedonia 2008 was initiated to obtain an overview of the current situation of the dragonfly fauna in Macedonia. Macedonia here refers to the territory of a former federal unit of the SFR Yugoslavia, and not to whole Macedonia. The records collected during this project are to become part of the data base for an Atlas of Odonata of Europe coordinated by Vincent Kalkman (European Invertebrate Survey, The Netherlands). Similar to other countries in this region, the odonate fauna of Macedonia is underresearched. So far, the largest research interest was directed towards the large lakes in Macedonia (Ohrid, Dojran and Prespa Lakes) (Filevska, 1954; Karaman, 1981; Karaman, 1984-85, Peters & Hackethal, 1986), the parts of the country under great influence of Mediterranean climate (Adamović, 1990) and the area around the capital city, Skopje (Adamović, 1949; Karaman, 1969; Peters & Hackethal, 1986). Some of the goals of Macedonia 2008 were: i) to visit places that had not been previously studied, ii) to re-visit places that have significantly changed compared to previous research and iii) to visit localities that are characteristic for this region.

Polillo is a small group of island (27 islands in total) east of central Luzon (Figure 1). It is made up of four main island viz. Polillo I, Patnanungan I, Jomalig I and Palasan I and several islets. This island group has relatively flat to gentle sloping terrain and the highest point is only 300 m asl (Mt. Maluhod) in Polillo Island (ca 700 km²) which is the largest in the group and the third largest island in greater Luzon biogeographic region.

In early 2007, I was invited by Dr. Michael Lau, Head of the China Programme of Kadoorie Farm & Botanic Garden (KFBG), to write a simple guide to the Odo nata of Hainan, China. KFBG is a Hong Kong-based conservation charity orga- nization, with strong links to tropical southern China, and is conducting a project to produce a series of basic fauna and flora field guides for Hainan Island, to be published in English and Chinese, but primarily aimed at older schoolchildren in China. I previously conducted field surveys of Hainan Odona ta with KFBG (as an employee or volunteer) in 1998, 1999 (twice), 2002 and 2005. Results of the three surveys conducted in 1998-1999 (one if which was also attended by Keith Wilson) were published by Wilson & Reels (2001). The results of the 2002 and 2005 surveys will appear as a chapter in a KFBG book about Hainan’s Yinggeling Nature Reserve, to be published in 2010. I also published a very brief, informal account of the 2005 survey in Agrion (Reels, 2006). On the basis of these past experiences, I gladly accepted the op tunity to write a field guide for KFBG.

During summer field work in 2005 and 2009 data on the distribution of dragonflies were obtained on the territory of Moldova. In August 2005, 9 species were recorded for the middle part of the Dniester river (surroundings of Sakharna). Between 28 June and 4 July 2009 dragonflies were studied in almost all parts of the country - 25 species were observed. Four species (Lestes macrostigma, Coenagrion ornatum, Coenagrion scitulum, Orthetrum brunneum) were recorded for the first time in Moldova. For many species the knowledge of their Moldovan distribution was improved. The habitats of every species were described, illustrated and preliminary maps of species distribution were prepared. Literature data were also analysed and a check list of Moldovan dragonflies was created containing 37 species. The presence of several species (including Nehalennia speciosa) in Moldova needs confirmation.

Three families in the superfamily Calopterygoidea occur in China, viz. the Calopterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese species has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the superfamily in South China.

Polillo Island is the largest among the Polillo group of islands. It is the third (ca 700sq km) largest island of the Luzon biogeographic region. The island lies in central eastern Luzon, at the western edge of Pacific Ocean and has a seasonal climate with distinct dry and wet season. The island is biologically rich with several insular species or subspecies (McGregor, 1910; Robinson, 1911; Manuel, 1957). The recent Odonata survey revealed the rich Odonata fauna of the island (Villanueva, 2010). This paper provides an update on the known Odonata based on recent fieldwork in 2010.
28
Based on the results of fieldwork and collecting in 2008 and 2009 and the evaluation of literature an updated national checklist of the Odonata of Kyrgyzstan is presented. The list comprises a total of 63 species, whereas 55 species were encountered in the field by the author, including five new for the country: Aeshna serrata, Onychogomphus lefebvrii, Orthetrum sabina, Crocothemis servilia, Selysiothemis nigra. 826 specimens of 49 species have been collected (dep. in coll. A. Schröter). All 55 species recorded in 2008 and 2009 are listed and annotated. Moreover, the unclear or controversial taxonomical status of several species is briefly debated. Interesting ecological observations include the emergence of Libellula quadrimaculata from running water and cleptoparasitism by Ischnura forcipata in spider webs.

A glance at the Odonata of the Cambodian coastal mountainous regions : end of dry season in 2010
(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.

Faunistic investigations on adult insects and molecular research on larvae have identified the existence of at least four species of Odonata on the Chatham Islands. The species resemble their New Zealand counterparts, although there are morphological deviations from the typical diagnostic features. Molecular evidence is not concordant with earlier morphological results as far as the genus Xanthocnemis is concerned. Genetic data suggest there are two species on the island while morphological investigations revealed just one. This topic needs further clarification and is given special atiention in the present study. The main aim of the present study is to establish the taxonomic position of Chatham Island Xanthocnemis species and its relation to New Zealand main island fauna. It also provides some data on the biology of the local species and estimates of key demographic parameters (i.e., survival and abundance). The results show that Chatham Islands inhabitants are close morphologically to their New Zealand main island counterparts. Between-island differences in wing area and abdomen-to-body length ratio were found, but were largely atiributable to the harsh environment on the Chatham Islands and its influence on body size. Chatham Xanthocnemis exhibited low survival rates and a great diversity of female colour morphs and certain behavioural traits (like underwater oviposition), which are suspected to be due to a composite influence of low summer temperatures, constant winds, and low pH. Ultimately, the taxonomic status of the Chatham Island Xanthocnemis species needs further confirmation based on molecular analysis of adults.
31
The Odonata fauna of the basin of the river Severskyi Donets in its middle current (Eastern Ukraine)
(2010)
A list of 57 Odonata species from 108 localities recorded in the basin of the river Severskyi Donets in its middle range (Eastern Ukraine) is provided. This compilation includes literature and museum data as well as results from field surveys realized between 2001 and 2009. Annotations to the history of regional odonate research are made. Brief descriptions of typical dragonfly habitats in the floodplain of Severskyi Donets are presented. Locality wise notes on the reproductive status for most of the species are made.
32
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.
33
During three field trips in 2006 and 2010 to Cuc Phuong National Park in northern Vietnam, a total of 19 anisopteran taxa was recorded. The most interesting records are documented here with field photographs of living specimens or collection material. Observations on their biology and behaviour are also noted.
34
Odonata were recorded and voucher specimens were collected between August 3- 13 and August 16-20, 2011. This account lists 51 species of Odonata for both islands, 47 species in Siargao and 24 species in Bucas Grande. Thirty seven species are new island records for Siargao Island while the 24 species recorded in Bucas Grande represent the first island records. Three species are new to science, and two of which (Drepanosticta schorri n. sp., Pseudagrion schieli n. sp.) are described in the present paper. Four species previously listed (Hämäläinen & Müller, 1997) remained elusive during the present survey.
35
On our trip to Cambodia from November 14th to December 1st 2010 eight new species for the country have been verified. These are Libellago lineata, Lestes praemorsus, Argiocnemis rubescens, Pseudagrion pruinosum, Epophthalmia frontalis, Indothemis carnatica, Indothemis limbata, and Orthetrum glaucum. This publication raises the list of Cambodian Odonatato over 90 published species. This figure is considered as less than half of the actual species number that inhabits the country. Given the scarce observations based on opportunistic samples only and largely insufficiently land coverage we predict that a few new species to the science are to be expected from the future research. This opens still many opportunities to study dragonflies in Cambodia at locations nobody ever has looked for Odonata before.
36
First records for Vietnam of Fukienogomphus promineusChao, 1954 and Gomphidia abbotti Williamson, 1908 are documented with emphasis on morphological details. The previously published record of Sieboldius gigas(Martin, 1904) in Do et al. (2011) has to be corrected into Megalogomphus sommeri (Selys, 1854).
37
The paper compiles records from four excursions to study the Odonata fauna of southern Guizhou, China. Between 2007 and 2010 in Xiaoqikong Park and Maolan National Nature Reserve, 104 taxa have been recorded. Some interesting species are discussed, compared with sibling taxa, and information on habitats and habits is given.
38
Odonata fauna of Diomabok Lake and its surroundings, Davao Oriental, Mindanao Island, Philippines
(2011)
During three visits in October and December 2010 and May 2011, a total of 56 Odonata species was recorded. All species reported here represent first Odonata records in the area. The most noteworthy discoveries were one novelty (Hydrobasileus vittatus) to the Philippine fauna and two first records (Tetracanthagyna brunnea and Aethriamanta gracilis) from Mindanao Island. Seven species represent either new species to science or potentially new species; one Drepanosticta and one Amphicnemis are new to science, and another Drepanosticta, Amphicnemis, Pseudagrion, Gomphidia and Urothemis are potentially new to science.

Results of the odonatological survey of the coastal SW regions of Cambodia on November 28 - December 11, 2001, are presented, including field notes, enumeration of all records by locality, discussion of interesting specimens and their taxonomy and of seasonality aspects. Fifteen (14 named) species have been added to the known fauna of Cambodia: Aristocypha fenestrella (Rambur, 1842), Rhinagrion viridatum Fraser, 1938, Lestes elatus Hagen in Selys, 1862, L. platystylus Rambur, 1842, Aciagrion tillyardi Laidlaw, 1919, Agriocnemis f. femina (Brauer, 1868), Archibasis viola Lieftinck, Ceriagrion calamineum Laidlaw, 1951, Mortonagrion aborense (Laidlaw, 1914), M. falcatum Lieftinck, 1934, Pseudagrion microcephalum (Rambur, 1842), 1948, Paragomphus capricornis (Förster, 1914), Hemicordulia undescr. spec., Macrodiplax cora (Brauer, 1867), Nannophya pygmaea Rambur, 1842, plus a provisionally identified Ceriagrion indochinense Asahina, 1976. The country list now achieves 106 named species (not counting Prodasineura verticalis sensu Asahina, 1983, C. indochinense and Hemicordulia sp.). Coeliccia megumii Asahina, 1984 is synonymised with C. kazukoae Asahina, 1984. The differences between Ceriagrion olivaceum Laidlaw, 1914 and C. calamineum Lieftinck, 1951 are discussed.
41
Based on data collected from literature, museum collections, national databases and personal communications, an up-to-date map of the worldwide distribution of Somatochlora sahlbergi is presented. A new hypothesis is presented indicating that occurrences are at least regionally correlated with palsa mires. Two examples of larval habitats in Europe are illustrated and described, including the first observation of reproduction in Norway and the first record of co-occurrence with Zygoptera in Europe. The exuvia of S. sahlbergi is illustrated and distinguishing features briefly discussed.
43
Six Odonata species were collected during night light trapping on the Mambilla Pla-teau, Taraba State Nigeria. Being predominantly diurnal insects, odonates captured in light traps have always been considered as an anomaly. The new data initiated an extensive interrogation of all records on Odonata collected near artificial light sources.A total of 415 records (402 published and 13 new) are presented here with a sum-mary of previous discussions and new discussion points. The general conclusion is that odonates are mainly confused by, rather than attracted to the light. New ave-nues for further research in this field are suggested based on previous important stu-dies undertaken on Odonata morphology and physiology.
44
The results of an odonatological expedition to the Hose Mountains in central Sarawak, Malaysian Borneo made in April 2011 are presented. During the two-week expedition more than sixty-three species of Odonata were collected, bring the number of species of Odonata known from the Hose Mountains to over ninety-three; a number greater than that recorded from a some of Sarawak’s National Parks. Species of particular interest collected on the expedition include Drepanosticta new species, Protosticta tubau Dow, 2010 and, most notably, Chlorogomphus manau Dow & Ngiam, 2011, which was discovered during the expedition.
45
Results of the odonatological survey of the coastal SW regions of Cambodia in August 12-28, 2011 are presented. Those include general notes on the Odonata fauna in late rainy season, enumeration of all records by locality, discussion of interesting specimens and their taxonomy, and notes on habitats and habits of some species. Of 87 named Odonata species encountered during the trip, 15 are reported for the first time for Cambodia, namely Aciagrion hisopa (Selys, 1876), Anax immaculifrons Rambur, 1842, Burmagomphus divaricatus Lieftinck, 1964, Gomphidictinus perakensis (Laidlaw, 1902), Merogomphus parvus (Kruger, 1899), Nepogomphus walli (Fraser, 1924), Idionyx thailandica Hamalainen, 1985, Macromia cupricincta Fraser, 1024, Macromia septima Martin, 1904, Macromidia rapida Martin, 1907, Agrionoptera insignis (Rambur, 1842), Lyriothemis elegantissima Selys, 1883, Onychothemis testacea Laidlaw, 1902, Orthetrum luzonicum (Brauer, 1868), Orthetrum testaceum (Burmeister, 1839). The country list now reaches 125 named species.
46
On 13 July 2010, in a woodland near the village of Verin Khotanan, Armenia, five males of Cordulegaster vanbrinkae were captured. These specimens are documented, compared with the holotype from Iran and discussed in detail. The current protection situation of this species in Armenia is briefly commented. In addition, the locus typicus information of the holotype from Iran is corrected and detailed.

54
Records of Odonata collected from Gunung Pueh and the surrounding area, in west Sarawak, in October 2012, are presented. 67 species were collected; two species were recorded in Borneo for the first time: Libellago stigmatizans and Copera ciliata. Othernotable records include Podolestes chrysopus, Telosticta gading, Agriocnemis mini-ma and Pseudagrion coomansi. Some additional, previously unpublished, records from the most western part of Sarawak are included in two appendices.
55
Notes on a small Odonata collection from Tawi-Tawi, Sanga-Sanga and Jolo islands, Philippines
(2012)
Sulu region is among the least explored faunal region in the Philippine archipelago. Odonatologically, this region is poorly studied until recently. Presently a survey conducted in July 1 – 14, 2011 revealed ten new records in Tawi-Tawi raising the total number of Odonata to 54. Three new species records were made for Sanga-Sanga raising the known number in that island to 34. Three species were recorded for the first time in Jolo raising the total number to 18. One new species of damselfly was found and several questionable and possible new species of dragonflies were documented.
56
A survey of Odonata in North Ethiopia, on the route Debre Libanos – Bahir Dar – Woldia – Hayk – Mile – Awash – Debre Zeyit crossing the provinces of Oromia, Amhara and Afar, in July 29 - August 10, 2012 yielded 38 species, including two endemics of Ethiopia and five species not hitherto reliably reported for this country in the literature: Pseudagrion commoniae (Forster, 1902), P. hamoni Fraser, 1955, P. salisburyense Ris, 1921, Bradinopyga strachani (Kirby, 1900) and Ictinogomphus ferox (Rambur, 1842). The number of Odonata species recorded in Ethiopia thus reached 104. Seventeen main localities were visited, on average showing 4.9 species per locality. A small branch of Jara River, Amhara, was the richest one (15 species). Comments on specimens of Pseudagrion spernatum Selys, 1881 and Nesciothemis farinosa (Forster, 1898) and notes on the country in general and particular habitats of Odonata are provided.

Dragonflies from mainland Yemen and the Socotra Archipelago : additional records and novelties
(2013)
The odonatological results of two field trips to mainland Yemen carried out mainly in summer 2005 and winter 2007, and to Socotra in winter 1999 are put on record. At 30 localities, 33 dragonfly species were collected, respectively observed. One species,Azuragrion somalicum, is new for mainland Yemen, and a second, Pseudagrion niloticum, is new for mainland Yemen and the Arabian Peninsula. Three species, Azuragrionsomalicum, Orthetrum julia, and Sympetrum fonscolombiiare new records for Socotra.
58
59
Odonata survey was conducted in Talaingod, Davao del Norte, Mindanao Island. Four major sites were explored in Barangay Santo Niño from December 26 – 30, 2012. Thirty five species under eleven families including one new species were found representing the first odonatological record in the province of Davao del Norte. Three species need further study while Orthetrum glaucum represents a new record for the island of Mindanao. Coeliccia exoleta population, a vulnerable species in the IUCN Red List of Threatened Species, was found.
60
The Odonata fauna of Balabac Island, Philippines was studied in March 2013. A total of 41 species under 33 genera were recorded. Twenty-eight species were recorded for the first time in the island. One genus – Mortonagrion was recorded for the first time in the Philippines. Mortonagrion astamii spec. nov. and Prodasineura poncei spec. nov. are new to science and are described. Three previously recorded species remained elusive and not seen during the survey.
61
62
A two week trip to Costa Rica was conducted between 26 May and 8 June 2013, sampling odonates in several provinces along the center to the pacific southern portionof the country. A total of 86 species in 34 genera were found, including 16 species of the genus Argia. Lists of all species by locality, photographs of live specimens, and illustrations and notes of described species of Argiaare presented to facilitate identification to other collectors.
64
66
Balut and Sarangani islands are two small landmasses situated off the coast of Davao Occidental, Mindanao Island. Despite recent increase on odonatological data from various islands in the Philippines, these two remote islands have never been explored. Hence, a short survey was conducted on first week of April and November 7 – November 14, 2010 on all freshwater systems in these two islands. Twenty-five species under seven families and 21 genera were found representing the first Odonata record for the two islands.
68
Specimens of Burmagomphus asahinai Kosterin, Makbun and Dawwrueng, 2012 and Burmagomphus divaricatus Lieftinck, 1964 from SW and NE Cambodia show differences in the development of the light pattern. One male of the latter species has unusual posterior spinules on posterior hamuli. Two males of Orientogomphus minor(Laidlaw, 1931) from the same locality in NE Cambodia have substantial differences in the thoracic and abdominal pattern. NE Cambodian specimens of Gomphidia abbotti Williamson, 1907 and Lamelligomphus castor (Lieftinck, 1941) have minor differences from data on these species from literature. Caution is necessary when composing and using keys for identification of the mentioned genera of gomphids.
69
In spring and summer 2008, the Odonata fauna of the Khabr National Park (Iran) was studied for the first time. Here, we present records of the representatives of family Libellulidae only. A total of twelve libellulid Odonata were found. Most of them are common species in Iran and other parts of Kerman province. Scarce Iranian species are Trithemis arteriosa and Zygonyx torridus.
70
A selection of duplicates from the collection of Michel Edmond de Selys Longchamps was found at the Übersee-Museum Bremen/Germany (UMB). Selys determined a lot of Odonata in the UMB collection and sent 80 European and 76 exotic species to Bremen on 23 April, 1875. According to the labels 121 specimens could be assigned to this shipment and eleven specimens must have been sent to UMB in later years. This collection includes two paralectotypes (Progomphus gracilis Hagen inSelys, 1853;Palaemnema nathalia Selys, 1886) and seven syntypes (Rhinocypha trifasciata Selys, 1853; Dysphaea dimidiata limbata Selys, 1859; Argia sordida Hagen inSelys, 1865; Oxyagrion dissidens Selys, 1876; Oxyagrion haematinum Selys, 1876; Oxyagrion pavi-dum Hagen in Selys, 1876; Telagrion longum Selys, 1876). In addition, a male specimen of Euphaea tricolor subcostalis Selys, 1873 might also belong to the original syntype series. Altogether three specimens with labeled nomina nuda(Diplax catharina Selys, Diplax fausta Selys, Dythemis bilineata Hagen) and two labeled with manuscript names (Diplax marcellina Selys, Perithemis ovate Bates) are in this collection.
71
A new species of the synthemistid genus Palaeosynthemis is described from the Trauna River valley in Western Highlands Province, Papua New Guinea. The new species is most similar to P. cyrene from which it can be distinguished, among other characters, by the coloration of the pterostigma (jet-black in the new species vs brownish yellow in P. cyrene) and of the wing bases (not darkened vs strongly darkened). The new species also differs from P. cyrene in having a narrow, almost parallel-sided yellow lateral synthoracic stripe and a well-defined yellow marking along most of the ventral margin of the metepimeron. In P. cyrene the lateral synthoracic stripe is markedly wider and tapered, and the yellow element along the ventral margin of the metepimeron is absent. Characters of the adult male are illustrated and the affinities of the species are discussed.
72
Odonata fauna of karst streams and rivers of South Herzegovina (Bosnia and Herzegovina, West Balkan)
(2014)
Results of the odonatological survey in the Neretva River Basin in South Herzegovinakarst region of Bosnia and Herzegovina conducted from April to August 2013 are presented. The area had been pre-assessed as insufficiently known in term of its Odonata fauna, but believed to be important habitat for several species of conservation concern, particularly Coenagrion ornatum, Ceriagrion tenellum, Caliaeschna microstigma, Lindenia tetraphylla and Cordulegaster heros. Moreover, freshwater habitats of the region are increasingly threatened due to climate change and the habitat destruction due to infrastructure and hydroenergy production projects. The focus of the study was set on the streams and rivers in Neretva, Trebižat, Trebišnjica and Bregava river valleys, Hutovo blato wetland, Mostarsko blato, Dabarsko and Fatničko polje. The survey resulted in 482 Odonata records of 49 species from 52 surveyed localities. Notable results include new distribution data on species of conservation concern, particularly six new localities of C. ornatum, nine of C. microstigma and five of C. heros. Comments on species of conservation concern and brief description of habitats at all surveyed localities are provided. New data on species of conservation concern are important for better conservation planning of dragonfly species and habitats in Bosnia and Herzegovina.
73
The results of two expeditions into the Ulu Baleh and Ulu Balui areas of the interior of Sarawak are presented, including data from forest that was pristine at the time of sampling but that was subsequently logged. A total of 74 species are recorded, notably including Coeliccia campioni, Coeliccia new species borneensis-group, Pericnemis spp., Heliogomphusblandulus, Leptogomphus pendleburyi, Chlorogomphus ?manauand Procordulia ?new species. A discussion of the results and potential differences in the odonate fauna of comparable logged and unlogged forest sites is given.
