The genera Scapania and Macrodiplophyllum have been studied in the Russian Far East. Macrodiplophyllum is represented by three species that are known in this genus. Scapania includes 38 species that are distributed among 12 sections. Keys are provided for all taxa found in the Russian Far East. All species based on the Far Eastern material are illustrated. Some corrections have been made in respect to the infrageneric structure of Scapania. Specifically, section Brevicaules R. M. Schust. was united with section Apiculatae H. Buch, S. sphaerifera H. Buch was transferred to section Aequilobae Müll. Frib., and accordingly, section Spheriferae Konstant. & Potemkin was synonymized with the latter. The understanding of the distributions of some species has been improved. S. parvidens Steph. was reevaluated at the species level. S. integerrima Steph., S. ligulata Steph. and S. ampliata Steph. are now excluded from the hepatic flora of Russia. Scapania magadanica S. S. Choi, Bakalin & B.-Y. Sun sp. nov. is described based on the combination of paroicous inflorescence, green to colorless two-celled gemmae, a rounded apex of the dorsal lobe, and a non-decurrent ventral lobe, all of which are not present in other taxa of the genus.

Чои С.С., Бакалин В.А., Сан Б.-Ю. Scapania и Macrodiplophyllum на российском Дальнем Востоке. Проведена обработка родов Scapania и Macrodiplophyllum для российского Дальнего Востока. Macrodiplophyllum представлен 3 видами, охватывающими все разнообразие рода. Scapania включает 38 видов, объединенных в 12 секций. Составленные ключи охватывают все таксоны, представленные на российском Дальнем Востоке. Для видов, изученных по дальневосточным материалам, составлены оригинальные иллюстрации. Внутриродовая структура рода Scapania подверглась некоторой переработке. Секция Brevicaules R. M Schust. объединена с секцией Apiculatae H. Buch, S. sphaerifera H. Buch перенесена в секцию Aequilobae Müll. Frib. и, таким образом, секция Spheriferae Konstant. & Potemkin была сведена в синонимы с последней. Распространение большинства таксонов было существенно уточнено. Восстановлен видовой ранг Scapania parvidens Steph. S. integerrima Steph., S. ligulata Steph. и S. ampliata Steph. исключены из флоры печеночников российского Дальнего Востока. Scapania magadanica S. S. Choi, Bakalin & B.-Y. Sun sp. nov. описана на основе пареции, зеленых до бесцветных выводковых почек, закругленной верхушки дорзальной лопасти и не сбегающей вентральной лопасти, - комбинации, ранее неизвестной внутри рода Scapania.
