Theridiidae is a large family of spiders, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, and the poisonous spider family. The diverse family includes over 2200 species in over 100 genera of three-dimensional space-web-builders found throughout the world. Theridiid spiders are  entelegyne  (have a genital plate in the female) araneomorph ecribellate (use sticky capture silk instead of woolly silk) spiders that often build tangle space webs and have a comb of serrated bristles (setae) on the tarsus of the fourth leg.
