抄録: Collection of adult chironomid midges were conducted during 3 day period from April 25 to 27, 1998, in areas along Shimanto River, western Shikoku Island, Japan, in night time with light traps at the town of Nakamura and Hiromi, and in daytime by sweeping with insect net at 8 localities along the main stream of the river and its branches, from near the mouth to the upstream portions. The chironomid specimens were preserved in 70% ethanol, and first examined under a stereomicroscope for classification, and those considered necessary for detailed examinations were dissected and mounted individually on slides in gum-chloral medium. By examination of 240 slide mounted specimens, 74 were identified as belonging to 42 different species of the subfamily Chironomidae, and 24 among them were described as new species in our previous paper. The rest specimens were classified into 36 species belonging to the subfamily Orthocladiinae, including 19 new species and 5 species new or rare to Japan, 1 species of subfamily Diamesinae new to Japan, and 9 species including 3 new species and 3 species new to Japan are belonging to the subfamily Tanypodinae, or a total of 46 species, including 22 new species and 9 species new to Japan, are recorded this time as members of these 3 subgenera. It was again demonstrated that the areas along Shimanto River are very rich in the chironomid fauna, and such large numbers of new species or species new to Japan were collected and identified this time.
