On the systematic placement of Pyreneplax Ossó, Domínguez & Artal, 2014 (Decapoda, Brachyura, Vultocinidae)

Abstract

Examination of the thoracic sternum and pleonal elements of a new male specimen of Pyreneplax basaensis Ossó, Domínguez & Artal, 2014 from the upper Eocene of northern Spain confirms its assignment to the family Vultocinidae Ng & Manuel-Santos, 2007 and reveals the presence of an old lineage (Pyreneplax and possible allies) that appeared during the Eocene, persisting to the present day. Izvleček V prispevku opisujemo nove fosilne ostanke primerka samca vrste Pyreneplax basaensis Ossó, Domínguez & Artal, 2014 iz zgornjega eocena na severu Španije. Ohranjene podrobnosti delov oprsja in repa potrjujejo njegovo uvrstitev v družino Vultocinidae Ng & Manuel-Santos, 2007 in razkrivajo prisotnost stare linije (Pyreneplax in sorodni taksoni), ki se je pojavila v eocenu in je prisotna še danes.
