Bostrychia calliptera (Montagne) Montagne (Rhodomelaceae, Rhodophyta), a new record for the central Gulf of Mexico

Bostrychia calliptera (Montagne) Montagne, collected from the mangroves of Sontecomapan Lagoon (Veracruz, Mexico), is a new record for the central Gulf of Mexico. Bostrychia calliptera differs from its closest ally, Bostrychia pinnata J. Tanaka et Chihara, in the presence of axial cortication and internal hyphae in the former and their absence in the latter. This record extends the known distribution of B. calliptera from Central America (Panama) to the Gulf of Mexico
