ODONATA FROM MONTENEGRO, WITH NOTES ON TAXONOMY, REGIONAL DIVERSITY AND CONSERVATION

摘要

The Odon. fauna of Montenegro was investigated during 2 field trips in 2009 and in 2011. In all, 105 localities were visited resulting in 50 observed spp. (52 taxa). Important populations of Lindenia tetraphylla and Selysiothemis nigra were found, that of the former is probably the most important one in Europe. The presence of Lestes parvidens, Caliaeschna microstigma, Cordulegaster hews and C. bidentata is confirmed. C. hews individuals show clear variation from the nominal type and are of an intermediate form with the ssp. pelionensis. Several populations of Gomphus schneiderii, which differ in thoracic and abdominal markings from typical schneiderii, were detected and criteria are given for the differentiation with G. vulgatissimus. Epitheca bi-maculata is a new sp. for Montenegro and represents the southernmost observation in its European range. The first populations of Trithemis annulata were discovered. A major emphasis was on the survey and diversity of the Mediterranean region. This regionhas a greater diversity than the Alpine region and several spp. of the Balkans are confined to it. Skadar lake has the greatest diversity of dragonflies and is home to several threatened and European protected species. Many populations of rare spp. in the coastal area are threatened by an increasing demand for water consumption by tourists and for agriculture use.
