Resumo: | Based on morphological studies, four species of Chondracanthus Kutzing were previously reported on the Brazilian coast: C. acicularis (Roth) Fredericq, C. elegans (Greville) Guiry, C. saundersii C.W.Schneider and C.E.Lane and C. teedei (Mertens ex Roth) Fredericq. In the present study, specimens of Chondracanthus were collected from intertidal and subtidal zones (up to 18m depth); morphological, molecular and phylogenetic analyses were performed using DNA barcoding (cox1) as a tool in a survey of Rhodophyta biodiversity in SAo Paulo state. Unlike what we expected, C. saundersii is widely distributed, and many specimens were misidentified as C. acicularis or C. teedei before this study, suggesting the necessity of an accurate revision in the previous identifications of the species of Chondracanthus in Brazil. Tetrasporangial and cystocarpic structures of C. saundersii are described for the first time. Our results confirm that the utilization of cox1 sequences as DNA barcode is an efficient tool to complement morphological identification for species of the genus Chondracanthus. |
