Arctoa (2015) 24: 14-20
Afoninia dahurica from the Transbaikal region of the East Siberia in Russia is described as a new species accommodated in a new genus of Funariaceae, based on molecular phylogenetic evidence from nrITS, trnL-F and psbA-trnH, that highlights the combination of strongly reduced double peristome with a well developed annulus of inflated revoluble cells. The exostome teeth are tapered to the base and attached to basal membrane with a plate that is less than one third of the cell of the endostome to which it adheres. The plant is known from few nearby localities in a xeric area of Dahuria, growing on soil near cliffs.
