A new Tournaisian (Early Carboniferous) conodont Siphonodella puchkovi sp. nov. is described from the shallow-water clayey-carbonate deposits of the Pechora-Kozhva Uplift (Pechora Plate). Morphologically Siphonodella puchkovi is similar to its ancestral species Siphonodella quasinuda Gagiev, Kononova et Pazuhin but differs from it by longer outer rostral ridge, platform outline, and rounded posterior tip of platform. The new species occurs in the L . crenulata Zone ( carinata local zone) of the middle Tournaisian, and is known from the Timan-Pechora and Donets basins. Together with Siphonodella carinata and Hindeodus cristulus the new species is characteristic of this zone in the shallow-water facies.
