6th International Congress of DipterologyJapanese Lipiniella species assigned to L. moderata Kalugina,1970 (Diptera, Chironomidae, Chironominae, Chironomini)Kobayashi, T. (1), R. Nakazato (2) & M.

Midges belonging tothis genus are actually rather common in the big rivers, lakes and marshes.To establish the true identity of the Japanese Lipiniella species was urgent.The genus Lipiniella comprises 4 described species: L. araenicola Sihlova,1961; L. moderata Kalugina, 1970; L. prima Shilova, Kerkis and Kiknadze,1992; and L. secunda Shilova and Prowiz, 1997. L. prima is describedbased on larval morphology and karyotype only. We examine themorphology of the Japanese specimens to establish if they truly belong inthe genus Lipiniella, and if so, if they are conspecific with any of thepreviously described species. As a result we consider the Japanese materialto include only one species, namely L. moderata. We also comparedGlyptotendipes goryoense ( = Demeijerea goryoensis) and Chironomusfujiprimus, and found them both to be junior synonyms of L. moderata.Japanese specimens of Lipiniella Shilova, 1961 are assigned to L.moderata Kalugina, 1970, and Glyptotendipes goryoensis Ree & Kim,1981 and Chironomus fujiprimus Sasa, 1985 are found to be juniorsynonyms of L. moderata.Key Words: Chironomidae, Lipiniella moderata, Japan∗∗∗∗∗∗∗∗∗∗136
