Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. [1] This diverse, globally distributed family includes over 3,000 species in 124 genera , [ 2 ] and is the most common arthropod found in human dwellings throughout ...
The adult female triangulate cobweb spider is 3 to 6 mm long (1/8 to 1/4 inch), with a brownish-orange cephalothorax and spindly, yellowish legs, and tiny hairs. The round, bulbous abdomen is creamy in color, with parallel purply-brown zigzag lines running front to back. This distinctive pattern sets it apart from other theridiids in its area.
The order Embioptera, commonly known as webspinners or footspinners, [ 2 ] are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. [ 3 ] More than 400 species in 11 families have been described, the oldest known fossils of the group being from ...

It has been included as a subfamily of the Hexathelidae, but is now recognised as a separate family. [1] All members of the family are native to Australia.
