(2017). Good illustrations are to be found elsewhere: for the general appearance of the colony, see Jäderholm (1903, as  Lytocarpus gracilicaulis), and for microscopic details Hirohito (1995, as  Halicetta gracilicaulis). Its systematic affinities with  Taxella eximia(Allman, 1874)are unsettled yet, as revealed by analyses with molecular markers ( Ronowicz et al. 2017; Moura et al. 2018), and both may prove conspecific.    Distribution  South Africa( Millard 1975), Red Sea ( Vervoort 1967), Indonesia( Billard 1913), Korea( Rho 1969), Japan( Jäderholm 1903; Hirohito 1995), Australia( Watson 1997). 2854853340 2016-08-23 KANACONO New Caledonia 210 -22.866667 PACIFIC OCEAN 1258 167.68333 6 7 MNHN-IK-2015-571 1
