Ecology and biodiversity studies

The presented work is based on the study of extensive material collected by Ezhkin A. K. in 2014–2018 from the islands of Kunashir, Iturup, Paramushir, and Shikotan. As a result of the study, the new list of species of the genus Rinodina for the Kuril Islands consists of 17 taxa. One species, Rinodina herrei H. Magn., is new to northeastern Asia and Russia, 14 taxa are new to the Kuril Islands. The genus Rinodina is represented by species with disjunctive distribution by 35.3 % (6 species). They are divided into two groups: East Asian – West American (R. herrei, R. megistospora) and East Asian – East North American (R. ascociscana, R. subminuta, R. tenuis and R. willeyi). East Asian species account for 17.6 % (3 species: R. hypobadia, R. subalbida and R. xanthophaea) of the known number of Rinodina species of the Kuril Islands.
