Abstract
Prorocentrum micans is an extremely variable dinoflagellate species, with many different local forms reported worldwide. Because of this morphological diversity, it is important to establish whether these various forms belong to P. micans sensu stricto. For this study, P. micans-like specimens were isolated from several localities in the southern coastal waters of Korea and Japan. The morphological characteristics and the molecular signatures of P. micans were re-examined. Moreover, a new Prorocentrum species, Prorocentrum koreanum sp. nov. was established through detailed light microscopy and scanning electron microscopy observations. Examination of the periflagellar platelets revealed that P. koreanum sp. nov. differs from P. micans. Furthermore, P. koreanum and P. micans exhibited different distribution patterns of trichocyst pores. Through molecular phylogeny analysis of small subunit (SSU) rRNA, internal transcribed spacer (ITS), and large subunit (LSU) rRNA sequence, we found P. koreanum to be more closely related to P. mexicanum and P. rhathymum than to P. micans. Additionally, ITS2 compensatory base changes also provide strong evidence to support P. koreanum and P. micans being separate species. (C) 2015 Elsevier GmbH. All rights reserved.
