DNA Sequence Analyses Reveal Two New Species of <i>Caloglossa</i> (Delesseriaceae, Rhodophyta) from the Skin of West Indian Manatees

Epizoic macroalgae collected from the skin of West Indian manatees included specimens of the red algal family Delesseriaceae. Morphological and <i>rbc</i>L sequence analyses indicated that these specimens represented two novel species of <i>Caloglossa</i>. One species, descri...

description Epizoic macroalgae collected from the skin of West Indian manatees included specimens of the red algal family Delesseriaceae. Morphological and <i>rbc</i>L sequence analyses indicated that these specimens represented two novel species of <i>Caloglossa</i>. One species, described here as <i>Caloglossa kamiyana</i> Freshwater, Cath.E. Miller & Frankovich sp. nov., had been previously studied and recognized as part of the <i>C. ogasawaraensis</i> species complex. The <i>rbc</i>L sequence divergence between <i>C. kamiyana</i> and other taxa within the complex ranged from 4.6–5.3%, and tetrasporangial mother cells are cut off from the lateral pericentral cells by oblique divisions instead of transverse divisions as in <i>C. ogasawaraensis</i>. The second species was resolved as a closely related sister species to <i>C. fluviatilis</i>, with a minimum interspecific sequence divergence of 2.0%. It was morphologically indistinguishable from <i>C. fluviatilis</i> except for one potential character—mostly one, instead of multiple rhizoids, developing from rhizoid-bearing pericentral and marginal wing cells. It is herein described as <i>Caloglossa manaticola</i> Freshwater, Cath.E. Miller & Frankovich sp. nov.
