Remarks

The possible synonymy of Ogmoconcha , described from the Lias δ of Germany ( Triebel 1941), and Hungarella , described from the Triassic of Hungary ( Méhes 1911), has long been debated but material from the type locality of Hungarella has yet to be observed to clarify this issue (e.g., Lord 1972, 1982). Here we agree with the position of Lord who stated that “it is preferable to call Lower Jurassic species which are congeneric with Ogmoconcha contractula Triebel, 1941 (type species of Ogmoconcha ) by the generic name Ogmoconcha rather than Hungarella since the synonymy of the two genera is unproved” ( Lord 1972: 332), and consider that the corollary position should be applied by restricting the use of Hungarella to Triassic species. Until the relationship of Ogmoconcha and Hungarella is clarified, we choose to only use Hungarella for Triassic species to avoid artificially rooting Ogmoconcha down to the Triassic and biasing our understanding of the diversity dynamics at the end of the Triassic ( Forel & Crasquin 2020). We thus follow Kristan-Tollmann (1977a, 1977b) and Lord (1982) in considering that:

• the valves of Hungarella are asymmetrical contrary to those of Ogmoconcha

• the anterior margin of the RV of Hungarella may display a rim or a spine but numerous marginal spines are diagnostic of Ogmoconcha
