Morphologically, the left and right valves of Hungarella are asymmetrical contrary to those of Ogmoconcha (Kristan-Tollmann, 1977a, b; Lord, 1982): in the absence of observable central muscle scars, all Triassic occurrences of Ogmoconcha and Ogmoconchella are re-attributed to the genus Hungarella.

In the Monte Gambanera area, the outcropping sediments are assigned to the Neo-Tethyan Mesozoic-Cenozoic complex which belongs to the so-called Imerese Succession (Lentini et al., 1987; Montanari, 1987; inter alias) or Imerese-Sicano Succession (Carrillat and Martini, 2009; Di Paolo et al., 2012).The Imerese Basin, where these sedimentary successions were deposited, was delimited by the .
