STUDIES ON THE CHIRONOMIDAE (DIPTERA, INSECTA) COLLECTED IN MONGOLIA

Collections of adult chironomids were carried out in Mongolia, Central Asia, located about midway between Europe and Japan, in August 1995 and also in August 1996. The specimens were preserved in 70% ethylalcohol, and individually mounted on slides in gum-chloral medium after digested in 10% hot KOH solution and dissected under stereomicroscope. A total of 345 male specimens were studied for species identification. As the results, a total of 42 species belonging to 23 genera were identified, among which 12 species are considered as belonging to the same one as those already recorded from Europe, and 11 species among them are also in common with those from Japan, and the rest 29 species are described here as new species. Three new genara were created in order to accept 4 new species among them.
