Remarks. In Tanida (2005, 2018), illustrations of adults of this species and those of H. selysi are mistakenly replaced each other (Kuhara et al. 2023). A larva described as Hydropsyche sp. HE by Tanida (1985) includes this species and H. selysi (Tanida, 1988, 1991b). Shimura (2015) recorded this species from Fukue-jima based on identification of the larval stage.
