Chironomus famiabeus Sasa, 1996 : 47 . syn. n. Chironomus ginzanabeus Sasa et Suzuki, 2001a : 9 . syn. n. Chironomus inabeceus Sasa, Kitami et Suzuki, 2001 ; 3. syn. n. Specimens examined: Japan : Toyama Pref., Family Park , holotype ♂ of Chironomus famiabeus , 23. vi. 1993 , M. Sasa [specimen No. 253:01 (NSMT-I-Dip-4931)] ; Hokkaido , Mt. Ginzan , holotype ♂ of Chironomus ginzanabeus , 1. ix. 2000 , H. Suzuki [specimen No. 403:013 (NSMT-I-Dip 5 383)] ; Fukushima Pref., Lake Inawashiro , holotype ♂ of Chironomus inabeceus , 17. viii. 2000 , K. Kitami [specimen No. 401:90 (NSNT-I-Dip-5377)] . In their original description of Chironomus inabeceus , Sasa et al . (2001) pointed out that the wing is entirely clothed in macrotrichia. However, we could not recognize this feature in the holotype . The shape of the anal point, superior and inferior volsellae support that C . famiabeus , C . ginzanabeus and C . inaabeus are junior synonyms of Glyptotendipes biwasecundus .
