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.
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.
This paper offers an explanation of each of the 44 scientific names given by Leopold Krüger (1861-1942) to odonate taxa together with that for the names of all the genera into which they are sorted now. But prior to that there is some information about the life and work of this scientist, and in the final part his preferences in odonatological nomenclature are compared with those in the names created by F.M. Brauer and F. Ris and some impressions of his studies on Neuroptera are presented and considerations about his aspirations in his work are given.
An explanation is presented for each of the 135 scientific names given to Odonata by F. M. Brauer (fossils and synonyms included), in addition the names of the actual genera in which Brauer’s species are now classified are explained. Prior to that part biographical information is given and Brauer’s merits in enlightening the taxonomy of dragonflies are analysed. Conclusions are drawn as to his preferences in odonatological nomenclature and finally the difficulties are discussed, which Brauer had to face in his taxonomic work.
This paper presents the faunistic results of three short field excursions conducted in spring and early summer of 2018 in Kosovo, considering dragonfly fauna one of the most understudied countries of Europe. This study presents first systematic dragonfly research in Kosovo. Within a total of 13 field days between end of April and end of June 2018, 60 sites were surveyed and 44 dragonfly species were found. Significant results include the first documented report of 15 species for Kosovo. New data on several other species with a broader European concern or generally rare on the West Balkan peninsula, i.e. Coenagrion ornatum, Anax ephippiger, Caliaeschna microstigma, Cordulegaster heros, C. bidentata, Somatochlora flavomaculata, and Sympetrum flaveolum, are also presented. The overview of all visited sites is included. Altogether, 47 dragonfly species are now reported for Kosovo.
The survey is based on specimens held at Museums in Australia, Belgium and Germany. Altogether 487 specimens of 31 species from Timor were examined. These include: a recent collection from TimorLeste of 148 specimens (25 species) at the Australian Museum Sydney, an historic collection from West Timor consisting of 338 specimens (20 species) of the excollection Eugène Le Moult, stored at the Institut Royal des Sciences Naturelles de Belgique in Brussels, and a single specimen from West Timor of the Coll. Ris stored at the Senckenberg Naturmuseum Frankfurt, Germany. The following nine species are reported from Timor for the first time: Agriocnemis pygmaea, Austroallagma sagittiferum, Ischnura heterosticta, Xiphiagrion cyanomelas, Crocothemis servilia, Neurothemis ramburii, Orthetrum pruinosum cf. schneideri, Potamarcha congener and Zyxomma obtusum. The female of Anax georgius is described and illustrated. An illustrated key to the Anax species of the Lesser Sunda Islands is given and specimens from the Lesser Sunda Islands formerly identified as Anax gibbosulus are considered to be Anax panybeus. Some characters of the Orthetrum pruinosum taxa group of species, Tramea stenoloba and female Zyxomma obtusum are discussed. Figures of the male appendages and genital ligulae of Austroallagma sagittiferum, Aciagrion fragile and Xiphiagrion cyanomelas are provided, as well as figures of the male secondary genitalia, appendages and the penis of Trithemis lilacina and the male appendages of Epophthalmia vittigera. A preliminary checklist for Timor including 36 species is given.
Phnom Tumpor is a scarcely accessible basalt table mountain in the Cardamom Mts. in Pursat Province of Cambodia. On top surface it bears tall evergreen forest (ca 1100 m a.s.l.), concealing a slow rivulet, O'Gran, being a chain of deep pools. It was examined odonatologically on March 1418th, 2019. Six common species were recorded in dry and burnt scrub on the Phnom Tumpor slopes and ten on the forested upper surface at O'Gran, among them Polycanthagyna erythromelas (Selys, 1891) and Macromia sp. cf. pinratani Asahina, 1987 for the first time in Cambodia. The peculiarities of the males of Coeliccia kazukoae Asahina, 1984 from Phnom Tumpor and the problem of distinguishing females of M. pinratani and M. moorei are discussed.
A small collection of Odonata from Nuku Hiva Island, Marquesas Islands is presented. It adds Anax guttatus as a new species to this oceanic group. Hemicordulia sp. nov. is reported, but not described because the same species has been sampled before and is pending a formal description. A short taxonomic discussion on observed morphological similarity of male anal appendages in taxa presently assigned to Amorphostigma, Hivaagrion and Ischnura east of New Caledonia is provided. Important considerations for biogeography of the Pacific Odonata are discussed too.
Odonatological results of a trip across the southern Far East of Russia, from nearly the border of North Korea to Khabarovsk from July 1st to 16th, 2014, are presented. In total, 50 species were recorded, including those with limited presence in Russia, such as Paracercion calamorum, P. hieroglyphicum, P. plagiosum (for this species the 3rd Russian locality is reported), Pseudocopera tokyoensis, Stylurus annulatus (2nd Russian locality), Sinictinogomphus clavatus; Trigomphus citimus, Macromia daimoji (3rd Russian locality), M. manchurica, Deielia phaon, Lyriothemis pachygastra (2nd Russian locality). For S. annulatus, M. manchurica and D. phaon the northernmost known localities in the world are reported. D. phaon, earlier reported from one locality in Russia, have been found in five localities in Primorye and for the first time reported for Khabarovskiy Kray in general and Bol'shekhekhtsirskiy State Nature Reserve in particular. A trend of mutual exclusion of two abundant Shaogomphus postocularis epophthalmus and S. schmidti is supposed: the lowermost Ussuri River / Amur River, respectively. Variation in Paracercion spp. and Macromia amphigena fraenata is discussed.
