Ber. Thätigk. St. Gallischen Naturwiss. Ges. 1876–77: 306. 1878. Pylaisiella extenta (Mitt.) Ando, J. Hattori Bot. Lab. 46: 384. 1979. Stereodon extentus Mitt., J. Proc. Linn. Soc., Bot., Suppl. 1: 95. 1859. Type: Nepal or Sikkim. Hooker 766, 771.
Pylaisiella falcata (Schimp. in B.S.G.) Ando var. recurvatula (Broth.) Ando, Phyta 1: 19. 1978. Stereodon subfalcatus (Schimp. in B.S.G.) var. recurvatulus Broth., Symb. Sin. 4: 123. 1929. Type: China. Sichuan (Setschwan), Yuenyan Co., Handel-Mazzetti 2327.
Species features of this species are very similar to those of Pylaisia polyantha (Hedw.) Schimp. in B.S.G. Pylaisia extenta differs from P. polyantha in having distinctly recurved leaf margins, longer leaf cells (50–60 µm), loosely arranged leaves that are erect or slightly falcate-secund, and more or less plicate.
