Family Ophiactidae

A total of 18 COI sequences trimmed to 554 bp were obtained after removing ambiguous aligned sites and were used to reconstruct the ML tree ( Fig. 48 ). Two main clades were detected within the family. Sub- Clade 02 represented all Ophiactis species recorded from the South China Sea. Ophiactis cf. perplexa ,

O. cf. brachygenys and O. profundi fell into two inter-clades within Sub-Clade 02 (Inter-Clades 2A and 2B) ( Fig. 48 ). Genetic distance values are provided in Suppl. file 9.
