Remarks. Habe & Kosuge (1966) and Kuroda et al. (1971) considered Triphora sematensis Oyama, 1954 a junior synonym of Triphoris conspersa E.A. Smith, 1875 . However, the name Triphora sematensis is not available because it was introduced without a description of the species and of the characters to differentiate it from other taxa, but only with a figure (ICZN Art. 13 (ICZN, 1999)).
