Radiation of the genus Dysdera (Araneae, Dysderidae) in the Canary Islands: The island of Tenerife

An overwhelming number of endemic species belonging to the spider genus Dys dera have been reported from the oceanic archipelago of the Canary Islands. A complete taxonomic revision is currently being performed in order to ass ess the extent of this species' radiation, as well as to supply enough data to place it in a phylogenetic framework. The present article is devoted to the Dysdera species inhabiting the island of Tenerife. A total of 22 speci es is recognized in Tenerife, including the cosmopolitan Dysdera crocota C. L. Koch 1839. Two new species are described: Dysdera guayota new species an d Dysdera hernandezi new species. Ten new synonymies are reported: D. moqui nalensis Wunderlich 1991 and D. vilaflorensis Wunderlich 1991 = D. brevispi na Wunderlich 1991; D. medinae Wunderlich 1991 = D. cribellata Simon 1883; D. inaequuscapillata Wunderlich 1991 = D. crocota; D. pergrada Wunderlich 1 991, D. pseudopergrada Wunderlich 1991, D. tabaibaensis Wunderlich 1991, D. teideensis Wunderlich 1991 and D. teneriffensis Strand 1908 = D. macra Sim on 1883: D. obscuripes Wunderlich 1991 = D. propinqua Ribera, Ferrandez & B lasco 1985. Sixteen species are redescribed: D. ambulotenta Ribera, Ferrand ez & Blasco 1985: D. brevisetae Wunderlich 1991, D. brevispina Wunderlich 1 991; D. chioensis Wunderlich 1991; D. cribellata Simon 1883; D. curvisetae Wunderlich 1987; D. esquiveli Ribera & Blasco 1986; D. gibbifera Wunderlich 1991; D. gollumi Ribera & Arnedo 1994; D. labradaensis Wunderlich 1991; D. macra Simon 1883; D. minutissima Wunderlich 1991; D. montanetensis Wunderl ich 1991; D. propinqua Ribera, Ferrandez & Blasco 1985; D. unguimmanis Ribe ra, Ferrandez & Blasco 1985 and D. volcania Ribera, Ferrandez & Blasco 1985 . The females of four species: D. brevisetae, D. brevispina, D. minutissima and D. montanetensis are described for the first time. Females formerly as signed to both D. gibbifera and D. volcania are considered to be incorrect identifications. A neotype is designated for D. macra. The presence of D. r ugichelis Simon 1907 in Tenerife is considered to be doubtful. Ecological a nd distributional patterns of the species are discussed.
