【摘要】The presence ofBiecheleria cincta (=Woloszynskia cincta) in the Chinese coasts is reported for the first time.In scanning electron microscope,three to five series of vesicles and an elongated apical vesicle (EAV) were visible in the epicone,and both the hypocone and the cingulum had three series of vesicles each.Thin sections revealed that B.cincta possesses stalked pyrenoids and an unusual eyespot consisting of a stack of cisternae with brick-like materials (type E),thus supporting its transfer from Woloszynskia to Biecheleria.Spiny cysts formed spontaneously in culture,with an encystment rate of around 20％.Both large subunit ribosomal DNA (LSU rDNA) and internal transcribed spacer region (ITS) sequences in 12strains from the Chinese coasts were determined.Phylogenetic analyses based on LSU rDNA and ITS sequences using Bayesian inference and maximum likelihood revealed two distinct ribotypes (referred to as ribotype A and B) in B.cincta.ITS region pairwise distances within B.cincta ranged from 0.024 to 0.072,suggesting the existence of a complex of cryptic species.
