Type locality. Xisha Island , Guangdong Province , China . Voucher. HEC 14756d, 22 September 2001 , Grand Baie (s.s. 11) . Ecology. Intertidal, about spring low tide level, wrapped around coral boulders. Also found drifting in the lagoon in huge quantities, locally forming a floating mass of 0.5 m thick. Distribution. China , Indonesia , Rodrigues (this paper), Tanzania . Notes. (1) See note for H. clathratus . (2) According to Tseng (1984: 186) this species is endemic to China . Since then it has been reported from one site in Indonesia ( Verheij and Prud’homme van Reine, 1993: 435 ), from the Philippines ( Trono, 1997: 123 ) and from several locations in Tanzania ( Coppejans et al ., 2000: 60 ). (3) When decaying, H. tenuis turns green. As a result it has been identified as Ulva reticulata in previous ecological studies of Rodrigues, based on the morphological resemblance.
