Theridula emertoni is a species of tangle web spider commonly found in the United States and Canada.[1] Prior to its formal description in 1954, specimens of T. emertoni were often classified as T. opulenta, a species with whom its range overlaps.[2] The species can be reliably distinguished from T. opulenta by the epigyne in females or by the pedipalp in males.[2]

T. emertoni from Virginia

Adult females are between 1.7 and 2.8 mm in length. Adult males are between 1.6 and 2.3 mm in length.[2][3]
