First findings of the clam shrimps Leptestheria Sars, 1896 and Imnadia Hertzog, 1935 (Crustacea, Conchostraca) in the western foothills of the Stara Planina Mountains, Serbia

Abstract

During 2004 conchostracans Imnadia and Leptestheria were recorded near the Serbian-Bulgarian border, in the foothills of the Western Stara Planina Mountains. Leptestheria occurred in relatively large density and was presented by adults of both sexes. Imnadia was identified only by resting eggs separated from the pond sediment. This is the first report of genus Imnadia in the Balkans, and also a first record of the second genus in the limnological area of the ‘Eastern Balkans’
