As the largest continent in the world, bound by the Pacific, Indian, and Arctic Oceans and the Mediterranean Sea, Asia is well-endowed in its geological and biological diversity. Not surprisingly, spiders abound in the vast expanses of its tropic and temperate forests, lofty mountain ranges and plateaus, and flood plains of its many river systems. However, it is only over the past two decades that we have begun to make a concerted effort to undertake the study of spider taxonomy, and correspondingly, to discuss the issue of conservation of their habitats.
