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.
Chigger mites of the African continent are reviewed using data acquired from the literature and examination of the collections deposited at the Royal Museum for Central Africa (Tervuren, Belgium) and the Natural History Museum (London, UK). All findings for 443 valid chigger species belonging to 61 genera are reported, along with details on their collection locality and host species. Three new synonyms are proposed: Straelensia Vercammen-Grandjean & Kolebinova, 1968 (= Anasuscuta Brown, 2009 syn. nov.); Herpetacarus (Herpetacarus) Vercammen-Grandjean, 1960 (= Herpetacarus (Lukoschuskaaia) Kolebinova & Vercammen-Grandjean, 1980 syn. nov.); Gahrliepia brennani (Jadin & Vercammen-Grandjean, 1952) (= Gahrliepia traubi Audy, Lawrence & Vercammen-Grandjean, 1961 syn. nov.). A new replacement name is proposed: Microtrombicula squirreli Stekolnikov, 2017 nom. nov. pro Eltonella myonacis heliosciuri Vercammen-Grandjean, 1965 (praeocc. Vercammen-Grandjean, 1965). Ninety new combinations are proposed. Keys to subfamilies, genera and subgenera of African trombiculid larvae and diagnoses of these taxa are given.
Results of a brief examination of the spring aspect of Odonata at the Abrau Peninsula and some nearby localities on 2127th May 2018 are presented. Lestes dryas and Caliaeschna microstigma are reported for the Peninsula for the first time, revealing the world northernmost record of the latter. Some old data of Odonata at Novorossiysk and some recent erroneous data on the Krasnodarskiy Kray are referenced and discussed. The known Odonata fauna of the Abrau Peninsula reaches 38 species.
In this study, a total of 108 Aphidiinae species, belonging to 18 genera, associated with 240 aphid species in 16 countries of the Middle East and North Africa are reviewed. 743 host aphidparasitoid associations are listed. New material was collected from various regions of Saudi Arabia during 2011–2013. Three species including Aphidius avenae Haliday, 1834, Aphidius platensis Brèthes, 1913 and Praon barbatum Mackauer, 1967 are first recorded for the fauna of this country. Lysiphlebus marismortui Mescheloff & Rosen, 1990 syn. nov. is classified as the junior synonym of Lysiphlebus confusus Tremblay & Eady, 1978. An illustrated up-to-date key to all known species of Aphidiinae that occur in the Middle East and North Africa is provided. The findings are discussed in relation to the overall parasitoid-aphid associations in the target investigated region.
The canaliculatus species group of Stenus (Nestus) is redefined. Four new Palaearctic species of the group are described and illustrated: S. (N.) alopex sp. nov. from the Putorana Highland and Taymyr Peninsula, Russia; S. (N.) canalis sp. nov. from SE Siberia and the Russian Far East; S. (N.) canosus sp. nov. from the Narat Mt Ridge, Chinese Tien Shan; S. (N.) delitor sp. nov. from C & SE Siberia. New distributional data as well as brief analyses of old records for fourteen species described earlier are provided from both Palaearctic and Nearctic material. S. (N.) milleporus Casey, 1884 (= sectilifer Casey, 1884) is revalidated as a species propria. S. (N.) sphaerops Casey, 1884 is redescribed; its aedeagus is figured for the fi rst time; the aedeagus of S. (N.) caseyi Puthz, 1972 as well as aedeagi of eight previously described Palaearctic species are illustrated anew. A key for the identification of all the known Palaearctic species of the group is given. A morphology and ecology based analysis of the main evolutionary trends within the group is provided. A lectotype is designated for S. (N.) melanopus Marsham, 1802; its Siberian and NE European records are supposed to be erroneous; the monotypic melanopus species group is erected.
More Odonata found at the Cardamonean foothills in Koh Kong Province of Cambodia in 2014-2018
(2018)
Still unpublished data on Odonata of the coastal foothills of the Cardamom Mts. in Koh Kong Province, SW Cambodia obtained in 2014-2018 are provided. Tetrathemis flavescens Kirby, 1889 is for the first time reported for Cambodia and Risiophlebia guentheri Kosterin, 2015 for SW Cambodia. The photographic records from this area of Gynacantha basiguttata Selys, 1882, Gynacantha demeter Ris, 1911, Heliaeschna crassa Krüger, 1899, Amphithemis curvistyla Selys, 1891 and Pornothemis serrata Krüger, 1902 have been confirmed by specimens. The known local faunas of two neighbouring rivulets in Koh Kong Province, rich in Odonata, are updated and summarised.
The article presents new faunistic data on 33 Odonata species, based on the material collected by the author in 2012, 2016 and 2017 and a systematic research in 2018 throughout the Nakhichevan Autonomous Republic (AR). Onychogomphus assimilis (Schneider, 1845) is a new record for the fauna of Azerbaijan. Eight species were registered for the first time for the territory of Nakhichevan AR: Lestes virens Rambur, 1842, Coenagrion scitulum (Rambur, 1842), Aeshna mixta Latreille, 1805, Anaciaeschna isoceles (Müller, 1764), Anax parthenope (Selys, 1839), Sympetrum sanguineum (Müller, 1764), Crocothemis erythraea (Brullé, 1832), and Selysiothemis nigra (Vander Linden, 1825).
