Genealogical exclusivity in geographically proximate populations of Hypochilus thorelli Marx (Araneae, Hypochilidae) on the Cumberland Plateau of North AmericaM Hedin
Department of Biology, San Diego State University, San Diego, CA 92182 4614, USA
Mol Ecol 11:1975-88. 2002..Hypochilus thorelli appears to have maintained morphological cohesion despite this limited female-based gene flow, suggesting a pattern of stasis similar to that observed at higher taxonomic levels in Hypochilus...
Phylogenetic utility and evidence for multiple copies of elongation factor-1alpha in the spider genus Habronattus (Araneae: Salticidae)M C Hedin
Department of Ecology and Evolutionary Biology, University of Arizona, USA
Mol Biol Evol 18:1512-21. 2001..The recovery of some novel clades, and the unexpected fragmentation of others, suggests areas requiring further phylogenetic attention...
Genetic diversification without obvious genitalic morphological divergence in harvestmen (Opiliones, Laniatores, Sclerobunus robustus) from montane sky islands of western North AmericaShahan Derkarabetian
Department of Biology, San Diego State University, San Diego, CA 92182 4614, USA
Mol Phylogenet Evol 61:844-53. 2011..Based on these data, it is obvious that S. robustus has undergone some level of cryptic diversification...

Inferring species trees from gene trees in a radiation of California trapdoor spiders (Araneae, Antrodiaetidae, Aliatypus)Jordan D Satler
Department of Biology, San Diego State University, San Diego, California, United States of America
PLoS ONE 6:e25355. 2011..Several Aliatypus species show disjunct distributional patterns in California (some are found on both sides of the vast Central Valley), and the genus as a whole occupies an impressive variety of habitats...
Multilocus genealogies reveal multiple cryptic species and biogeographical complexity in the California turret spider Antrodiaetus riversi (Mygalomorphae, Antrodiaetidae)James Starrett
Department of Biology, San Diego State University, San Diego, California 92182 4614, USA
Mol Ecol 16:583-604. 2007..Species diversification appears to have pulsed in the Late Miocene/Early Pliocene, a timing consistent with biogeographical reconstructions for many Californian taxa, and a time of turbulent geological activity in the region...
