Dear Koh,
Thanks for this photo which shows this Pleurobranchaea with it typically shaped egg ribbon. I am interested in your identification as P. japonica Thiele, 1925 as Marcus & Gosliner (1984) consider that the species is unidentifiable from Thiele's original description. They suspect P. japonica is possibly a synonym of P. maculata. I guess the safest procedure is to place you species as Pleurobranchaea cf. japonica until the taxonomy of these animals is clearer.
Best wishes,
Bill Rudman
