  • Taxonomic Study of the Pagurus Forbesii "Complex" (Crustacea
    Taxonomic study of the Pagurus forbesii "complex" (Crustacea: Decapoda: Paguridae). Description of Pagurus pseudosculptimanus sp. nov. from Alborán Sea (Southern Spain, Western Mediterranean Sea). GARCÍA MUÑOZ J.E.1, CUESTA J.A.2 & GARCÍA RASO J.E.1* 1 Dept. Biología Animal, Fac. Ciencias, Univ. Málaga, Campus de Teatinos s/n, 29071 Málaga, Spain. 2 Inst. Ciencias Marinas de Andalucía (CSIC), Av. República Saharaui, 2, 11519 Puerto Real, Cádiz, Spain. * Corresponding author - e-mail address: [email protected] ABSTRACT The study of hermit crabs from Alboran Sea has allowed recognition of two different morphological forms under what had been understood as Pagurus forbesii. Based on morphological observations with various species of Pagurus, and molecular studies, a new species is defined and described as P. pseudosculptimanus. An overview on species of Pagurus from the eastern Atlantic and Mediterranean Sea is provided. Key words: Pagurus, new species, Mediterranean, eastern Atlantic. 1 Introduction More than 170 species from around the world are currently assigned to the genus Pagurus Fabricius, 1775 (Lemaitre and Cruz Castaño 2004; Mantelatto et al. 2009; McLaughlin 2003, McLaughlin et al. 2010). This genus is complex because of there is high morphological variability and similarity among some species, and has been divided in groups (e.g. Lemaitre and Cruz Castaño 2004 for eastern Pacific species; Ingle, 1985, for European species) with difficulty (Ayón-Parente and Hendrickx 2012). This difficulty has lead to taxonomic problems, although molecular techniques have been recently used to elucidate some species (Mantelatto et al. 2009; Da Silva et al. 2011). Thirteen species are present in eastern Atlantic (European and the adjacent African waters) (Ingle 1993; Udekem d'Acoz 1999; Froglia, 2010, MarBEL Data System - Türkay 2012, García Raso et al., in press) but only nine of these (the first ones mentioned below) have been cited in the Mediterranean Sea, all of them are present in the study area (Alboran Sea, southern Spain).

As the habitat is under pressure by tourism and the species has been found sensitive to the side-effects of tourism, e.g. trampling and cleaning of algal belts from beaches, it is likely that the population has declined. Outside the HELCOM area the species can be found in the north-eastern Atlantic and North Sea, as well as along European coasts from southern Norway to the western Mediterranean. © HELCOM Red List Benthic Invertebrate Expert Group 2013 www.helcom.fi > Baltic Sea trends > Biodiversity > Red List of species SPECIES INFORMATION SHEET Talitrus saltator Distribution map The georeferenced records of species compiled from the databases of the Swedish Species Information Centre (Artportalen) and the Leibniz Institute for Baltic Sea Research (IOW), and from Zaddach (1844), Drzycimski & Nawodzinska (1965), and Weslawski et al.

Introduction Some coleopteran insects, talitrid amphipods and oniscoidean isopods, are typical organisms which burrow at upper shore levels of sandy beaches (see review by McLachlan and Jaramillo, 1995). When active over the beach surface, they move away from their burrowing zones, to which they return in response to various stimuli which guide the individuals in a direction perpendicular to the coastline (Scapini, 1988; Scapini *Corresponding author.

It is also responsible for some functions previously undertaken by Welsh Government. Our purpose is to ensure that the natural resources of Wales are sustainably maintained, used and enhanced, now and in the future. We work for the communities of Wales to protect people and their homes as much as possible from environmental incidents like flooding and pollution. We provide opportunities for people to learn, use and benefit from Wales' natural resources. We work to support Wales' economy by enabling the sustainable use of natural resources to support jobs and enterprise. We help businesses and developers to understand and consider environmental limits when they make important decisions. We work to maintain and improve the quality of the environment for everyone and we work towards making the environment and our natural resources more resilient to climate change and other pressures. Evidence at Natural Resources Wales Natural Resources Wales is an evidence based organisation. We seek to ensure that our strategy, decisions, operations and advice to Welsh Government and others are underpinned by sound and quality-assured evidence. We recognise that it is critically important to have a good understanding of our changing environment.
