A Chromosomal Hybrid Zone in the Australian Huntsman Spider, Delena Cancerides (Araneae, Sparassidae) - Evidence for a Hybrid Zone Near Canberra, Australia

Abstract

Data are presented that indicate the presence of a hybrid zone between two chromosomal races of the endemic Australian spider Delena cancerides. Electrophoretic data verify the hybridising taxa as members of the Victorian telocentric race and a chain-carrying race. Evidence is presented that indicates the hybrid zone is of natural origin, as opposed to being the result of human introductions.
