Abstract

Eight new species for the Republic of Tuva were revealed in the author’s herbarium collection: Calliergon richardsonii (Mitt.) Kindb., Coscinodon cribrosus (Hedw.) Spruce, Hymenostylium recurvirostrum (Hedw.) Dixon, Isopterygiopsis pulchella (Hedw.) Iwats., Loeskypnum badium (Hartm.) H. K. G. Paul, Plagiobryum demissum (Hook.) Lindb., Pseudocalliergon turgescens (T. Jensen) Loeske, Tayloria lingulata (Dicks.) Lindb. Herbarium labels are quoted, and the distribution features of the species are discussed. The same for the three species which previously were known in the Republic of Tuva by single specimens – Fissidens osmundoides Hedw., Pseudocalliergon trifarium (F. Weber et D. Mohr) Loeske, Indusiella thianschanica Broth. et Müll. Hal. The last species is in the Red Data Book of the Russian Federation (Dudareva et al., 2008) and also in the Red Data Book of the Republic of Tuva (Pisarenko, Bakalin, 2018).
