To the revision of the Upper Ordovician Bilobia Cooper (Strophomenida, Brachiopoda)

  • A. A. MadisonEmail author


The diagnosis and species composition of Bilobia Cooper, 1956 (family Leptestiidae, Strophomenida, Brachiopoda) are specified based on literary data and collection from the Leningrad Region. In particular, the cardinal process with cleft shaft and trifid myophore and denticles along the area of ventral valve are adduced to the diagnosis. A new species, B. alichovae sp. nov., from the Sandbian Stage of the Leningrad Region is established.
