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

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