The new species Icriodus alchedatensis sp. nov., I. kuzbassiensis sp. nov., I. lebedyankensis sp. nov. and Latericriodus sp. E are described from stratotype sections of the Mazalovy Kitatian Regional Substage (Middle Givetian) from the Kolyvan-Tom folded area. The taxa of the genus Icriodus belong to two lineages within the genus Icriodus the I. struvei lineage and the I. regularicrescens lineage according to the Weddige's (1977) concept.
