Genus Hungaroleberis n. gen.

Etymology. referring to the country of its type locality and with reference to the extant genus Cylindroleberis . Type species: Hungaroleberis retiferus n. sp.

Other species:

? Myodocopida gen. nov. sp. nov. (Crasquin et al. 2010, figs. 23. D’, E’, F’)

Cypridina gussevaae Crasquin-Soleau, 1998 (Crasquin-Soleau & Baud 1998, pl. 7, figs. 3–4.) Hungaroleberis sp. (this study, figs. 6/4–6.)

Type locality. Somhegy , Bakony Hills, Hungary.

Type level. Bajocian, Humphresianum Zone, Bed 3.

Diagnosis. Cylindroleberididae with valves ovoid in lateral view; rostrum and rostral incisure weakly developed; posterior margin arched without caudal process; valve surface reticulate or smooth.

Remarks. Compared to the Cretaceous species Mesoleberis hollandica Kornicker, van Bakel, Fraaije & Jagt, 2006 , Hungaroleberis lacks the linear indentation below the incisure and is smaller in size. According to Kornicker and Sohn (2000) the poorly-developed rostrum and incisure is characteristic for the superfamily Cylindroleberidoidea. These features can be observed on Hungaroleberis . Unfortunately, the specimens are complete, closed carapaces, and the muscle scar pattern cannot be examined.

Occurrences.
