The biserial interambulacral series of plates adapically distinguish this from all living Laganina. This taxon is apparently identical to Taiwanaster Wang, who gives a much fuller description. The detailed placement of this taxon is problematic because simple internal supports and simple food grooves are common to all juvenile scutellines. The taxon has a striking resemblance to the Miocene Kewia Nisiyama, 1935, but this too is probably based on small individuals of Scutellaster, Echinarachnius or Scaphechinus (see Nisiyama for illustrations of comparable juvenile Scaphechinus mirabilis) Mooi (1990) showed clearly that this was a minaturized scutelline and not a fibulariid.
