Remarks

Hiatobairdia sp. 3 is very close to several species already known from the literature, but the conspecificity of our material with these species is impossible to ascertain because the RV of cthe omplete carapace is broken posteriorly. Hiatobairdia sp. 3 is relatively close to Hiatobairdia subsymmetrica KristanTollmann in Kristan-Tollmann et al., 1980 from the Rhaetian of Iran ( Kristan-Tollmann et al. 1980), but the presence of the diagnostic ridge underlying the ventral margin is not verifiable here and our specimens have a relatively shorter and larger AB, as well as a shorter and less pointed PB. The slight indentation visible at the PVB of the RV could relate Hiatobairdia sp. 3 to Hiatobairdia labrifera Kristan-Tollmann in Kristan-Tollmann et al., 1980 from the Rhaetian of Iran ( Kristan-Tollmann et al. 1980), but it is difficult to ascertain that the observed indentation is not related to preservation bias. For these reasons, and until additional material can be observed, the present species is kept in open nomenclature.
