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.

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 Some additional, previously unpublished, records from the most western part of Sarawak are included in two appendices.

Libellula virgo Linnaeus, 1758 auf Grönland : eine Neubewertung der Beobachtung von Fabricius (1780)
(2012)
The record of 'Libellula virgo' in south-western Greenland by O. Fabricius in the 1770ies is reassessed. It is inferred that the specimen was most probably a female Calopteryx maculata. Morphological characteristics presented by Fabricius are com-pared with those of similar species from continental North America that might have reached Greenland. Origin and transportation of the specimen by accidental wind drift are discussed in some detail.

Ein Brief von Michel-Edmond Baron de Selys Longchamps (1813–1900) an Friedrich Förster (1864–1918)
(2012)
In der odonatologischen Sonderdrucksammlung des Naturkundemuseums Senckenberg (Frankfurt a.M.) fand sich ein Originalbrief von Michel-Edmond Baron de Selys Longchamps (Lüttich, Belgien) an den deutschen Odonatologen Friedrich Förster (Schopfheim), datiert 15. Februar 1896. Das Dokument bezeugt nicht nur den Kontakt zweier Forscher, sondern gibt auch Einblicke in die Art und Weise, wie Selys die Publikation seiner Forschung plante und vorbereitete. Das Faksimile des Briefes, eine typographische Umschrift und eine Übersetzung ins Deutsche sind beigefügt.

Records of Odonata collected above 800m a.s.l.on Gunung Penrissen in western Sarawak are presented. A short note on the location of Mount Merinjak, the type locality of several species, is included. Notable records include two new species from the Platystictidae, Bornargiolestes species and Acrogomphus jubilaris. Previously unpublished records from Annah Rais, a location at the foot of Gunung Penrissen, made in 2005 and 2006, are included in an appendix.

In February 2012, Odonata were recorded and voucher specimens collected in Luzon, The Philippines. The focus of study was set on localities near Dinapigue and San Mariano (Isabela Province), sites in Casiguran (Aurora Province) and on Polillo Island (Quezon Province). 60 Odonata species were recorded. Three are new to science and have been formally to be described. Four species were recorded for the first time in Luzon. Amphicnemis furcata and Diplacodes nebulosa were rediscovered after several decades since they were last documented from Luzon.

Karst poljes (or poljes) are specific geological formations of the Dinaric Alps and are important wetland areas of high biodiversity value. The dragonfly fauna of poljes in Bosnia and Herzegovina is poorly researched and mostly unknown. In order to in-vestigate dragonfly species and habitats in these specific and interesting habitats, field research was conducted from April to October 2011 in Livanjsko polje (west Bosnia), the largest periodically flooded karst polje in the world. The number of re-corded species indicates high species richness of this area, 41 dragonfly species in total were observed, of which 25 species are new for the research area. Description of habitats and dragonfly communities from 34 surveyed localities is presented. The most interesting are the records of Chalcolestes viridis (Vander Linden, 1825), na-tionally rare species and NATURA 2000 species Coenagrion ornatum (Selys, 1850). The results of this research significantly contribute not only the knowledge of dragonfly fauna of poljes but also the overall knowledge of dragonfly fauna of Bosnia and Herzegovina.

Die Sammlung von Wolfgang Lopau enthält 915 Libellenimagines von 80 Taxa, die vor allem in Griechenland gesammelt wurden. Schwerpunkt sind Serien von in Griechenland vorkommenden Taxa mit noch unbefriedigend geklärterSystematik. Die Sammlung wurde an das Forschungsinstitut und Naturmuseum Senckenberg in Frankfurt überstellt.

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.
