Nigma is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967.[2] They have a wide distribution, including Eurasia, North America, and Northern Africa.[1] N. walckenaeri is one of the biggest members of the Dictynidae, growing up to 5 millimetres (0.20 in) long. They are translucent green and sometimes have red or black markings on the abdomen.[3]
