INV 2014.99. 12.1 14.0 9.2 4.8 Remarks – This rather globose, uniplicate and fully costate species was recently discussed by VÖRÖS (2009, 2014); that served the basis of the identification of our specimens.

“ R.” hungarica was described by BÖCKH (1874), who recognized its similarity to “ R.” plicatissima Quenstedt, 1852 , but mentioned some differences between the two species. Subsequently, many authors regarded the two species as synonymous, with plicatissima as senior synonym. Recently, following the detailed revisions by TOMAŠOVÝCH (2006) and considering the data given by DULAI (1992, 2003), VÖRÖS (2009) restored Böckh’s species name hungarica for the forms which do not have planareas, but show fine riblets on their flat or gently convex lateral parts. The species hungarica is placed here to Calcirhynchia on the basis of serial sections of “ Calcirhynchia plicatissima ”, published by DULAI (1992, 2003). C. hungarica was widely recognized in the Sinemurian and Pliensbachian of the Alpine-Mediterranean region, but was recently recorded also in south Germany and Turkey.
