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

This study continues studies on the taxonomy and distribution of Dysdera in the Canarian archipelago. Four new species are described: Dysdera andamanae sp. n., D. arabisenen sp. n., D. tibicena sp. n. and D., yguanirae sp. n. Four new synonymies are reported: D. bailadero Wunderlich, 1991 and D. paucisetae Wunderlich, 1991 = Dysdera iguanensis Wunderlich, 1987, D. tamadabaensis Wunderlich, 1991=D. paucispinosa Wunderlich, 1991; D., sinuosa Wunderlich, 1994=D., tilosensis Wunderlich, 1991. Six species are redescribed: D. bandamae Schmidt, 1973, D. iguanensis Wunderlich, 1987, D. insulana Simon, 1883, D. paucispinosa Wunderlich, 1991, D. tilosensis Wunderlich, 1991 and D. verneaui Simon, 1883; and neotypes are designated for D. insulana and D. verneaui. The presence of the following species in Gran Canaria is reported for the first time: D. iguanensis, formerly only collected on Tenerife, D. insulana, previously of doubtful location, and D. levipes, known from Tenerife and La Gomera. Morphological affinities, ecology and distribution of the species are discussed. (C) 1997 The Norwegian Academy of Science and Letters.
