Contribution to the knowledge of the Odonata fauna of Bosnia and Herzegovina – Results of the ECOO 2012

Abstract

As a part of the 2nd European Congress on Odonatology (ECOO 2012), which was held in the beginning of July 2012 in Belgrade (Serbia), a post congress excursion to Bosnia and Herzegovina was organized. Between 6 and 12 August 2012, altogether 36 localities in three biogeographical regions throughout Bosnia and Herzegovina were surveyed, and 52 dragonfly species were found. This represents 83% of the hitherto recorded dragonfly species for the country. The most significant results are the second record and a new locality of Somatochlora metallica, second record of Coenagrion hastulatum, and first observation of the strong population of Lindenia tetraphylla for the country. New records of rare and/or threatened species, i.e. Coenagrion ornatum, Ceriagrion tenellum, Caliaeschna microstigma, Cordulegaster heros and Selysiothemis nigra, are also reported. The records of the most interesting species are briefly discussed from the aspects of biogeography and nature conservation.Kot del drugega evropskega odonatološkega kongresa (ECOO 2012), ki je v začetku julija 2012 potekal v Beogradu (Srbija), je bila organizirana pokongresna ekskurzija v Bosno in Hercegovino. V času med 6. in 12. julijem 2012 je bilo v treh biogeografskih regijah pregledanih 36 lokalitet in popisanih 52 vrst kačjih pastirjev, kar je 83 % vseh znanih vrst kačjih pastirjev za Bosno in Hercegovino. Med pomembnejšimi je bilo zabeleženo drugo pojavljanje in novo nahajališče kovinskega lesketnika (Somatochlora metallica), drugo pojavljanje barjanskega škratca (Coenagrion hastulatum) in prvo opažanje populacije velike peščenke (Lindenia tetraphylla) za državo. Poročamo tudi o novih nahajališčih redkih in/ali ogroženih vrst: koščičnega škratca (Coenagrion ornatum), rdečega voščenca (Ceriagrion tenellum), bledega vetrnjaka (Caliaeschna microstigma), velikega studenčarja (Cordulegaster heros) in temnega slaniščarja (Selysiothemis nigra). Najzanimivejše najdbe so na kratko opisane z biogeografskega in naravovarstvenega vidika.
