Recently, it has become clear that there are two clades in Liobagrus reinii, which can reasonably be judged as separate species. In this study, we attempted to clarify the differences in distribution and habitat of the two clades of Liobagrus reinii in the Gonokawa and the Ota River Systems by using environmental DNA analysis metabarcoding. In the Gonokawa River System, the number of the present sites and environmental DNA concentrations of clade 1 were higher than those of clade 2. In the Ota River System, the number of the present sites and environmental DNA concentrations of clade 2 were higher than those of clade 1. In both river systems, clade 1 tended to be found at lower elevations and clade 2 at higher elevations.
