Theridula is a genus of cobweb spiders, found in many (mostly tropical) parts of the world. Species vary in size from 1 to 3.5 mm in length.[1]

In females, the abdomen is wider than long, with a hump or horn on each side, and sometimes a posterior median horn.[2][3] The pedipalp in males is simple, lacking a conductor or theridioid tegular apophysis.[4][5]

Theridula spiders are frequently found on bushes or tall grass where they rest on the undersides of leaves near their webs.
