A form of the species found in Korea and Japan , A. hygrometricus var. koreanus , was named by V.J. Stanĕk in 1958 ; it was later ( 1976 ) published as a distinct species — A. koreanus — by Hanns Kreisel . As pointed out by Fangfuk and colleagues , clarification of the proper name for this taxon must await analysis of A. hygrometricus var. koreanused specimens from the type locality in North Korea .
