Abstract: | The authors describe Mixtacandona elegans n. sp.,M. pietrosanii n. sp., M. tabacarui n. sp. and present new data on the systematics and biogeography of the following Mixtacandona groups: ljovuschkini,hvarensis and riongessa.Mixtacandona elegans n. sp. belongs to the group ljovuschkini. The carapace is very elongated and has markedly assymetrical valves. The species has been found in a porous aquifer in southeastern Bulgaria. M. pietrosanii n. sp. belongs to the group hvarensis. The 3rd antennular segment and the 2nd endopodial segment of the cleaning leg have each two setae. The species lives in porous aquifers in the Danube plain in Roumania. M. tabacarui n. sp. (gr. riongessa) has a triangular left valve with a pointed dorsal protuberance. The species has been found in wells fed by karstic water in southern dobrodgea (Roumania), on the Black Sea coast. |
