Summary. Two Japanese species, Ceratrimeria takaoensis (Kinoshita, 1916) and C.

yasumatsui (Uchida, 1940), were redescribed based on fresh material, including that from the type localities and using modern morphological criteria. The main diagnostic characters of the genus Ceratrimeria are also discussed. In addition, nucleotide sequences of the mitochondrial cytochrome c oxidase subunit 1 and 16S ribosomal RNA genes of specimens obtained from the type localities of both congeners are analyzed allowing for their species statuses to be confirmed. Barcoded specimens are deposited in the National Museum of

Nature and Science, Tsukuba, Japan and the DNA sequence data are available in the International Nucleotide Sequence Databases.
