Fifteen holotypes of Asian Hesperiidae taxa described by Shu-iti Murayama were examined, and their taxonomic status is discussed. We confirm that five are valid names while the rest are synonyms as indicated partially by previous authors. Valid species-level names are Aeromachus matudai (Murayama), Aeromachus bandaishanus Murayama &Shimonoya, Coladenia pinsbukana (Shimonoya &Murayama), and Sebastonyma suthepiana Murayama &Kimura. Valid subspecieslevel name is Ochlodes yuchingkina Murayama &Shimonoya. In order to settle the taxonomic status of Pedesta masuriensis cuneomaculata Murayama, masuriensis and tali were studied morphologically and molecularly. As a result, we consider that masuriensis and tali are two different species and treat cuneomaculata as a junior subjective synonym of tali.
