Late instars of 3 littoral Cafius Curtis species [Cafius fucicola Curtis, C. nauticus (Fairmaire), C. vestitus (Sharp)] are described for the first time by using sequences of mitochondrial gene. In total, 13 unknown larvae were collected in association with adults from the Nearctic and Palearctic regions. The partial cytochrome oxidase II (CO II) gene was sequenced from the unknown larvae and several identified adult specimens for adults-larvae association. The range of intraspecific p-distance was from 0 to 2.30% and the minimum interspecific p-distance was 14.46% between Cafius nauticus and C. vestitus. Parsimony and distance analyses were conducted and individuals of a single species were always grouped closely together. Based on these results, the unknown larvae were identified and diagnostic characters of the species are provided, with illustrations of features.
