Location: island: Xisha Island; country: China ; stateProvince: Hainan Taxon discussion Maximum size of 18 cm Fig. 2 . Dark brown (nearly black) with blue streak on each scale, blue lines and spots on head and white spot on middle of upper back. Coral thickets interspersed with open sand or dead coral in 1-5 m ( Allen and Erdmann 2012 ). What we captured underwater in Xisha Islands is the state of the juvenile fish, which is very different from the adult fish. We have checked the main domestic fish checklists ( Liu 2008 , Chen and Zhang 2015 , Shen and Wu 2011 ) and relevant literature, but there is no record of this species. Therefore, we believe it is a newly-recorded species in China.
