Abstract

This is the first in a series of checklists which will review taxonomical, biogeographical and ecological publications on Japanese Trichoptera. This part deals with 10 species belonging to 4 genera of Hydroptilidae and 31 species belonging to 5 genera of Lepidostomatidae.
In Hydroptilidae we suggest four taxonomical problems: 1) Hydroptila itoi KOBAYASHI and Stactobia japonica IWATA should be compared with similar species from the adjacent country; 2) descriptions of Hydroptila usuguronis MATSUMURA and Oxyethira angustella MARTYNOV are insufficient for species identification; 3) many descriptions of larvae and cases are also insufficient for species identification; 4) four undescribed species are in the collections of the authors.
The Japanese Lepidostomatidae have been intensively studied in recent years. However, two taxonomical problems remain: 1) generic status of four species, Dinarthrodes albardanus (ULMER), D. albicorne (BANKS), D. elongatus MARTYNOV and D. kasugaensis TANI, has not been clarified; 2) nine undescribed species have been collected.
