Theridula emertoni

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]
