Abstract
The species name Kovalevskiella elisabethae n. sp. is proposed for a new taxon of a Recent ostracod found in interstitial sediments of the alluvial plain of the Danube in the surroundings of Vienna, Austria. The main characters that differentiate Kovalevskiella elisabethae n. sp. from its congeners K. bulgarica, K. cvetkovi, K. dani, K. rudjakovi and K. phreaticola are based on the morphology and chaetotaxy of antennula, antenna and mandible. Important diagnostic characters of the new species are the 5-segmented antennula, the presence of 2 setae on the posterior margin of its fourth segment, the presence of only 1 seta (besides the conjoined seta and aesthetasc) on its last segment, as well as the presence of 1 seta on the basis and 3 on the endopodite of the mandibula. An identification key for the Recent species of the genus is provided.
