Family Linoproductidae Stehli, (Brachiopoda) from the Upper Moscovian of the Middle Carboniferous of the Moscow Region

Species from the family Linoproductidae sensu str. from the Podolskian-Myachkovian deposits of the Moscow Region are revised and redescribed. The peculiarities of the arrangement of spines on the ventral valve are used as a basis for a new taxonomic structure. A new genus Linipalus, which appeared in the Podolskian time and was widespread in the Late Carboniferous and Early Permian, is established. Three new species of the genus Linispinus Lazarev, 2006, and one new species of the genus Linipalus gen. nov. are described.
