On the presence of the genus Branchinecta Verrill, 1869 (Crustacea,Anostraca) in Yugoslavia

The genus Branchinecta Verrill, 1869 is represented in Yugoslavia by two species: Branchinecta ferox (Milne-Edwards, 1840) and Branchinecta orientalis G.O. Sars, 1901. The first species was collected in the steppe-like province of Banat, Pannonian Lowland, and in the lowland around the Skadar Lake, Montenegro, the second only in the province of Banat.On the basis of rich material of both species, a detailed study of the most essential morphological characters has been carried out and comparisons have been made with data in the literature. In B. ferox, significant morphological deviations are not found, whereas, in B. orientalis, essential features are clearly ascertained which were previously unknown or were not stated with sufficient precision. B. ferox is known to appear in small, temporary, natronsoda water rainpools, while B. orientalis has been found in a large temporary inundation pool with a high content of natronsoda and salt in the water.
