Introduction Neosiphonia was segregated from Polysiphonia sensu lato , one of the largest rhodophyte genera with approximately 200 species reported worldwide (Kim et al. 2000), based on the production of trichoblasts on successive segments, rhizoids cut off from pericentral cells by a cross wall, procarps bearing a three-celled carpogonial branch, spermatangial branches arising from a branch of the trichoblasts, and spiral arrangement of tetrasporangia (Kim and Lee 1999, Bustamante et al. 2012). Many recent studies on Neosiphonia have focused on reports of

farming is members of the order Ceramiales, including two common genera, Polysiphonia Greville and Neosiphonia M.S. Kim et I.K. Lee (Fletcher 1995, Hurtado et al. 2009). The genus Neosiphonia was originally described by Kim and Lee (1999) based on specimens collected from Bangpo on the western coast of Korea. This genus is morphologically similar to the genus Polysiphonia , but differs by bearing trichoblasts on successive segments in a spiral pattern, spermatangial axes produced from the branch of trichoblasts, a rhizoid cut off from pericentral cells, a three

Rhodophyta (Guiry and Guiry 2014). Neosiphonia was segregated from Polysiphonia by Kim and Lee (1999). Neosiphonia/Polysiphonia species are widely distributed worldwide. To date, 12 Neosiphonia/Polysiphonia species have been reported from Indonesia (Silva et al. 1996, Atmadja and Prud’homme van Reine 2012, Bustamante et al. 2013). Neosiphonia echinata (Harvey) N. Mamoozadeh et D.W. Freshwater was originally described as Polysiphonia echinata Harvey from Key West, Monroe County, Florida by Harvey (1853) and then transferred to the genus Neosiphonia by

Lumpur 50603, Malaysia * Corresponding author Five species of the red algal order Ceramiales are reported from Malaysia for the first time, and their charac- teristic features are described: three species of Hypoglossum (Delesseriaceae), H. rhizophorum Ballantine et Wynne, H. caloglossoides Wynne et Kraft and H. simulans Wynne, Price et Ballantine, and two species of Rhodomelaceae, Laurencia caduciramulosa Masuda et Kawaguchi and Neosiphonia savatieri (Hariot) M. S. Kim et I. K. Lee. Small deciduous branchlets of Laurencia caduciramulosa are documented to be genuine

following five species of marine red algae are reported from Malaysia for the first time and their charac- teristic features are described: two species of Martensia (Delesseriaceae, Ceramiales), M. australis Harvey and M. fragilis Harvey, two species of Herposiphonia (Rhodomelaceae, Ceramiales), H. pacifica Hollenberg and H. vietnamica Pham, and Neosiphonia flaccidissima (Hollenberg) M. S. Kim et I. K. Lee (Rhodomelaceae, Ceramiales). The presence of Polysiphonia scopulorum Harvey in Malaysia is confirmed. Introduction Our research on the Malaysian marine algae, which
