New Congerian Species and Their Similarity with Congeria banatica from the Pannonian Sediments in Northern Croatia

Sažetak
Congeria baschi n.sp. and Congeria susedana n.sp. are two new species from the Pannonian sediments of the Medvednica Mts. (NW Croatia). C. baschi n.sp. was found in the Lower Pannonian limestones, and C. susedana n.sp. was collected from the Upper Pannonian marls.
Relationships with the affiliated taxa enable reconstruction of a phyletic lineage beginning with Congeria soceni JEKELIUS, through C. baschi n.sp. to Congeria banatica HÖRNES. C. banatica is the ancestor of two branches, leading to C. susedana n.sp. and C. vugroveci SREMAC, respectively. Dreissenomya digitifera (ANDRUSOV) is the probable descendant of C. vugroveci.
The accompanying assemblages of fossil molluscs and ostracods from the same horizons facilitate the precise stratigraphic and palaeoenvironmental positioning of the new taxa.
