Anthiadidae (Fairy basslets or Streamer basses)
Etymology: Plectranthias: Bleeker (1873) disagrees with the generic placement of Plectropoma anthioides by Günther. He, therefore, erected Plectranthias to accommodate Pl. anthioides. The name is presumably the combination of the first part of Plectropoma (plectrum), and anthias. Plectrum = Plektron = πλῆκτρον (Greek, plektron = anyhting to strike with, spur + Greek, anthias = a fish, Ref. 45335); normanby: Named for its type locality, Normanby Island; noun in apposition.
Taxonomic Remarks
Apparently a junior synonym of Pelontrus takasei (Ref. 138265).
