Inventory no. according to Pšenička et al. (2017). Obrhel (1957: Sbor. Ústř. Úst. geol., Odd. paleont. 23: 550/556) states "Holotyp je deponován ve sbírkách Národního muzea v Praze, akc. č. 36525"/"Holotypus wurde in den Sammlungen des Nationalmuseums in Prag (akc. N. 36525) deponiert".

PFNR administrator's note: There are two levels of specimens' registration in the National Musem, Prague (the Czech Republic) – the chronological evidence (first-step registration) and systematical evidence (final registration), respectively. The inv. no. listed by Obrhel (1957) represents the chronological evidence, that one used by Pšenička et al. (2017) already the systematical evidence.

Original diagnosis/description
