Revision of the Genus Ablabesmyia (Diptera, Chironomidae, Tanypodinae) in Korea

Out of the 12,100 slide-mounted specimens of Chironomidae collected throughout Korea from February 1977 to March 2016, 271 (2.2%) were from the genus Ablabesmyia (Diptera, Chironomidae, Tanypodinae). These 271 specimens were re-examined and eight species were identified, with three of these species shown to be new to science (A. hanea n. sp., A. microlongistyla n. sp., and A. paralongistyla n. sp.). It was discovered that A. monilis reported in 1981 and A. longistyla reported in 2009 had been misidentified, and corrected as A. prorasha in the present study. Among the eight species found from Korea, A. prorasha was predominant (37.8%), followed by A. longistyla (28.9%), and A. monilis (20.4%). A key of the eight species of Ablabesmyia found in Korea is provided.
