Adolfia siratschoica (Ljaschenko) and Adolfia krestovnikovi (Ljaschenko) are accepted as zonal species of the Petino and Voronezh Horizons of the Frasnian Stage of the Russian Platform. However it was established that these species do not belong to the genus Adolfia. The former species was recognized as the nomenclatural type species of Ljaschenkovia gen. nov. and the latter species was recognized as the type species of Tokmospirifer gen. nov. The comparative analysis provided of the shell structure, microornamentation, and shell interior of the type species of Ljaschenkovia gen. nov., Tokmospirifer brevis gen. et sp. nov., and Adolfia solita Ljaschenko is presented. © 2010 Pleiades Publishing, Ltd.

Nordella orbiculata (Ljaschenko, 1959) and N. subquadrata Ljaschenko, 1973 are revised based on the topotypical material from the collection of A. I. Ljaschenko. Based on data on the morphology, microornamentation, and shell structure Nordella is shown to have characters closely similar to Warrenella Crickmay, 1953 and, therefore, should be considered as its junior synonym. A new species, W. timanimedia sp. nov., is described from the Upper Devonian of Middle Timan. © 2013 Pleiades Publishing, Ltd.
