The genus Japewiella Printzen, gen. nov. is separated from Japewia T phi ns
berg and placed in the family Lecanoraceae. Japewiella pacifica Printzen, s
p, nov. is described as new. The species is closely related to the southwes
tem European J. carrollii (Coppins & P. James) Printzen, comb. nov. and the
East Asian J. djagensis (Zahlbr.) Printzen, comb, nov. Differences between
Japewia and Japewiella are discussed. Like the closely related Megalaria H
afellner and Tasmidella Kantvilas, Hafellern, & Elix, Japewiella seems to b
e a genus of humid temperate and subtropical regions, whereas the two known
species of Japewia show a boreal-(sub)arctic-alpine distribution.
