Abstract
In Western Australia, six species of the red algal genus Herposiphonia are known from the low-intertidal to shallow subtidal zones in tropical to warm-temperate regions. Here, we transfer the poorly known Leveillea pectinata Decaisne to Herposiphonia based on a morphology and DNA barcoding of specimens collected from Cape Peron, south of Perth, Western Australia. Herposiphonia pectinata is characterized by a branching pattern of three determinate branches (d) between indeterminate laterals (i) (d/d/d/i), terete determinate branches arising from the same dorsal position (not deflected from side to side), 20-30 segments long with 11-13 pericentral cells per segment, and a lack of vegetative trichoblasts. Cystocarps are located medially on fertile branches and spermatangial branches with a sterile tip are secundly arranged. Morphological comparisons are made with Australian and closely related species: Herposiphonia akidoglossa, Herposiphonia monilifera, Herposiphonia pectinella, Herposiphonia rostrata, and Herposiphonia nuda. DNA barcoding of COI-5P sequences show that H. pectinata is clearly separated from specimens from the Hawaiian Islands and the Iberian Peninsula.
