Seven species new to science are described, illustrated and compared with closely related taxa. Of them, one species, i.e.: Coppinsidea vernadskiensis S. Y. Kondr., T. O. Kondratiuk et I. Yu. Parnikoza is from the Argentine Islands, Western Maritime Antarctic Peninsula, Jacke lixia hosseussii S. Y. Kondr., L. Lőkös et J.-S. Hur, from South America (Argentina and Uruguay), Loekoeslaszloa reducta Yoshik. Yamam. et S. Y. Kondr. from Eastern Asia (Japan), Orientophila viticola S. Y. Kondr., L. Lőkös et J.-S. Hur from Eastern Asia (South Korea), Ovealmbornia ovei S. Y. Kondr., L. Lőkös, I. Kärnefelt et A. Thell, and Xanthokarrooa elsiae S. Y. Kondr., L. Lőkös, I. Kärnefelt et A. Thell from Africa, as well as Oxneria imshaugii S. Y. Kondr. from North America. The new combination Jackelixia australis (for Xanthoria parietina var. australis Zahlbr.) is proposed. Jackelixia hosseussii is for the first time recorded as host for the lichenicolous fungus Arthonia anjutii S. Y. Kondr. et Alstrup. The latter species is for the first time recorded from South America. Intralichen christiansenii (D. Hawksw.) D. Hawksw. et Cole is for the first time recorded from South Korea.
