Genus Apheoorthina Havlíček, 1949
Type species: Apheoorthina ferrigena Havlíček, 1949 (by original designation); Třenice Formation , middle Tremadocian; Prague Basin, Czech Republic .
Remarks. —Outside the Czech Republic and NW Argentina, the genus Apheoorthina has been reported with interrogation from the lower Floian ( Prioniodus elegans Zone ) of Estonia ( Rubel 1961). The Estonian material referred to as Apheoorthina? daunus (Walcott 1905) , however, lacks the typical irregular angular costellae of the genus. Moreover, the notothyrial platform is transversely elongated and non bilobed as in Apheoorthina ( Rubel 1961: pl. 1: 2).
