 note = {The chironomid fauna in the deep lake, Lake Sai, Japan, was investigated in March, 2009. Thirteen (8 males and 5 females) chironomid midges were collected with a sweeping net around the boat house and 81 (44 males and 37 females) chironomid midges emerged in the laboratory. They were identified as 11 species belonging to four subfamilies, i.e., 7 species of Chironominae, 1 species of Orthocladiinae, 1 species of Prodiamesinae and 2 species of Tanypodinae. At the deepest Station 4 (65.5 m in depth), we could not collect chironomid midges. However, only Micropsectra chuzeprima Sasa, 1984 was collected at Station 5 (56.6 m). At Stations 6 (29.6 m) and 3 (18.8 m), two species, M. chuzeprima and Procladius choreus (Meigen, 1804), were collected. On the other hand, at the shallowest Station 1 (4.9 m), we collected nine chironomid species, and the most numerous species in this collection was Polypedilum nubeculosum (Meigen, 1804) with a total of 41 individuals collected. In previous reports, a total of 16 species were collected from around the lake. We additionally describe 10 species from Lake Sai in this study. Only one species, P. nubeculosum, was common to the earlier report and the present study. As a result, there are 26 species recorded from Lake Sai., Article, Medical Entomology and Zoology. 62(4):243-247 (2011)},
