ACLETO O., Cesar  e  ZUNIGA A., Reina. Revision of the Peruvian species of Sebdenia (Sebdeniales, Rhodophyta) and description of Cryptonemia anconensis sp. nov. (Halymeniales, Rhodophyta). Rev. peru biol. [online]. 2011, vol.18, n.1, pp.97-112. ISSN 1727-9933.

Six species of Sebdenia have been recorded for the Peruvian marine seaweed: Sebdenia afuerensis, S. chinchensis, S. heteronema, S. lapathifolia, S. limensis and S. polydactyla (Howe 1914, Dawson et al. 1964, Acleto 1980). In the present study, we re-evaluated the Peruvian species of Sebdenia on the basis of type specimens and herbarium material of the Herbarium San Marcos (USM). We concluded that only Sebdenia flabellata previously identified as Sebdenia polydactyla is present in our marine flora. The last five species correspond to Cryptonemia genera and are described and illustrated as new combinations and Cryptonemia anconensis as new species.
