Scarabaeidae Beetle Taxonomy and Biogeography

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. pauciserae 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 Tenenfe and La Gomera. Morphological affinities, ecology and distribution of the species are discussed.
