Acta Botanica Malacitana 35. 2010 165203. NEW RECORDS FOR THE BENTHIC MARINE FLORA OF CHAFARINAS ISLANDS (ALBORAN SEA, WESTERN MEDITERRANEAN)María ALTAMIRANO1*, Julio DE LA ROSA2, Marianela ZANOLLA1,Virginia SOUZA-EGIPSY1 and Javier DÍAZ3Recibido el 8 de septiembre de 2010, aceptado para su publicación el 1 de octubre de 2010Nuevas citas para la ﬂ ora bentónica marina de las Islas Chafarinas (Mar de Alborán, Mediterráneo occidental)Keywords. Chafarinas Islands, geographical distribution, Mediterranean Sea, seaweeds.Palabras clave. Islas Chafarinas, corología, macroalgas marinas, Mediterráneo.The Chafarinas Islands, of volcanic origin, are located in the Alboran Sea, in front of the north coast of Morocco, less than 2,5 miles far away from Ras el Ma, and near the frontier with Algeria (UTM coordinates 30SWD59). It is formed by three islands, named Isla del Congreso, Isla del Rey and Isla de Isabel II, the latter being the only one housing a permanent military population.The marine biota of the Chafarinas Islands is very rich, mainly because of the inﬂ uence of both Atlantic and Mediterranean waters, which deﬁ ne the biogeographical importance of the archipielago. The knowledge on the marine ﬂ ora of the islands has been achieved in a scattered way in time (Conde 1984, Navarro & Gallardo 1989, González & Conde 1994, Flores & Conde 1998, Benhissoune et al. 2001, Benhissoune et al. 2002a, Benhissoune et al. 2002b, Benhissoune et al. 2003), with no new record since more than ten years ago (Altamirano 1999). Up to now the marine ﬂ ora has revealed to include more than 130 speciﬁ c and infraspeciﬁ c taxa, including cyanobacteria, macroalgae and the seagrass Posidonia oceanica L.The aim of this work is to provide 12 new records to the marine ﬂ ora of the Chafarinas Islands, 6 Rhodophyta, 2 Phaeophyceae, 3 Chlorophyta and 1 seagrass. One taxa, Bryopsis cupressina J.V. Lamouroux, represents a new record for the coast of Morocco. We conﬁ rm the presence and expansion of the invasive species Asparagopsis taxiformis (Delile) Trevisan in the three islands after the ﬁ rst record of the species in 1999 (Altamirano 1999). Furthermore, we report the presence of Asparagopsis armataHarvey in sympatry with A. taxiformis in the islands.Samples were collected from Isla del Congreso, Isla del Rey and Isla de Isabel II in April 2010 by SCUBA diving and snorkeling, carried to the laboratory of the Estación Biológica Islas Chafarinas and immediately identiﬁ ed. Herbarium sheets of the different taxa have been included at the University of Málaga Herbarium (MGC). Herbarium acronyms follow Holmgren et al. 1990. This work has been developed in the framework of the projects “ALIAN” CGL2008/01549 (Ministerio de Ciencia e Innovación) and P09-RNM-5187 (Consejería de Innovación, Ciencia y Empresa, Junta de Andalucía), and the Research Fellowship from the Instituto de Estudios Ceutíes 2009.166 Acta Botanica Malacitana 35. 2010RHODOPHYTABANGIACEAEBangia fuscopurpurea (Dillwyn) Lyngbye“Muelle Chico”, Isla de Isabel II. 05.04.2010.

The gametophyte of the species was present in the infralittoral zone of the three islands with different coverage degrees and batimetric range, from 0 to -14 m depth always on hard substrata. The hosting community was mainly the photophilic ones formed by Halopteris ﬁ licina (Grateloup) Kützing and Dictyota dichotoma (Hudson) J.V. Lamouroux; some thalli have been observed to grow on the rhizome of P. oceanica of Isla del Rey. It was found in sympatry with A. armata in Isla del Congreso, in “La Laja” at -7 m depth and at “La Sangre”, at -1 m depth. This species is considered among the ten most invasive macroalgal species in the Mediterranean Sea and presently is spreading widely along Andalusian coast (Altamirano et al. 2008), although the invasive status on the north coast of Morocco is still unknown, with the species not recorded yet (Benhissoune et al.2002b). The tetrasporophytic stage Falkenbergia has been observed in the islands, although we cannot conﬁ rm the species.Bonnemaisonia asparagoides (Woodward) C.
