As a result of a multi-year survey, we recognized four species including a new species of the subgenus Uresipedilum from the Yaeyama Islands, the Ryukyus, Japan. Polypedilum (Uresipedilum) paraconvictum sp. nov. is described. P. (U.) classiglobum Zhang et Wang (2004) P. (U.) bingoparadoxum Kawai et al. (1998) and P. (U.) iriofegeum Sasa et Suzuki (2000) are re-described. The first species is newly recorded from Japan, and the second species is new to the Ryukyus. The diagnostic characters of the subgenus are discussed.
