Two psephenid beetles, Eubrianax granicollis Lewis and E. ramicornis Kiesenwetter, are common species on the main islands of Japan (i.e. Honshu, Shikoku and Kyushu), but diagnostic characters for larval identification are unknown. Two types of field‐collected Eubrianax larvae from Honshu and Kyushu were discriminated based on the distributions of granules on the dorsal surface. These larvae were assigned to E. granicollis and E. ramicornis by comparing them with larvae of the two species obtained via laboratory rearing. The two species were also identified unambiguously on the basis of their mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Larval and pupal morphology are described based on laboratory‐reared specimens.
