Abstract The examination of sandy mud samples collected at 5–67 m depths in 2005 and 2009 on the Aegean and Levantine coasts of Turkey revealed the presence of specimens belonging to a new species of Lumbrineris (Polychaeta, Lumbrineridae), L. geldiayi. This species is mainly characterized by having maxillae III as an arcuate, unidentate plate; reddish aciculae; anterior and posterior parapodia with postchaetal lobe always longer than prechaetal lobe, median parapodia with both lobes of similar length; and composite multidentate hooded hooks with short blade and simple multidentate hooded hooks of two sizes, preacicular hooks being bigger than postacicular hooks. A key to Lumbrineris species from Mediterranean Sea is included. Keywords Lumbrinerids . Aegean Sea . Levantine Sea . New species . Lumbrineris
Introduction The genus Lumbrineris de Blainville, 1828 comprises 36 valid species worldwide, and 4 species in the Mediterranean Sea and on the coast of Turkey (Carrera-Parra 2006a; Kurt L. F. Carrera-Parra (*) El Colegio de la Frontera Sur, Unidad Chetumal, Laboratorio de Poliquetos, Apartado Postal 424, Chetumal, QR 77000, México e-mail: [email protected] M. E. Çinar : E. Dagli Faculty of Fisheries, Department of Hydrobiology, Ege University, 35100 Bornova, Izmir, Turkey
et al. 2007; Çinar 2009). The Mediterranean species are L. coccinea (Renier, 1804), L. latreillii Audouin & Milne Edwards, 1834, L. nonatoi Ramos, 1976 and L. perkinsi Carrera-Parra, 2001. The latter species, which is considered as an alien species (Çinar 2009), was previously reported as L. inflata Moore, 1911 from the Mediterranean Sea (Italian coasts) by Giangrande et al. (1981). The widely reported species in the Mediterranean Sea, L. gracilis (Ehlers, 1868), was transferred to the genus Hilbigneris Carrera-Parra, 2006 by Carrera-Parra (2006b). Capaccione-Azzati (1991) introduced the name L. cingulata for the Mediterranean Sea fauna; however, we consider this record as doubtful because this species has a restricted distribution to Magellanic biogeographic province (Orensanz 1990; Carrera-Parra 2006a). The other Mediterranean species, L. labrofimbriata de Saint-Joseph, 1888, was considered as invalid as specimens assigned to this species belong to juveniles of a Lumbrineris species (Carrera-Parra 2006a). During work performed on the Aegean and Levantine coasts of Turkey to determine structures of zoobenthic communities in the areas, a large number of Lumbrineris specimens were found in sandy mud sediment. The comparison of these specimens in comparison with the previously described species of the genus revealed that these specimens belong to a new species. This paper
