 Drepanoistodus suberectus (Branson & Mehl, 1933) from the Mójcza Limestone. Diagnoza The P elements with a weakly separated external area, S1 elements flat with a somewhat elongated external tip of the base and a concave posterior side. Porównanie Distinctions between the species and its predecessor, D. basiovalis, are somewhat problematic and additional biometric studies are necessary to clarify the issue. It remains far from clear whether the Late Ordovician populations from the North American Midcontinent are conspecific with the European ones. Somewhat arbitrarily I late populations of Drepanoistodus in the Mójcza section, starting from the discontinuity surface, are classified here. Autekologia Występowanie geograficzne Probably cosmopolitan. Zasięg czasowy Abundant in the Lanvirn and L1andeilo but sparse in the Caradoc at Mójcza.
