Anderella is a genus of synziphosurine,[1] a paraphyletic group of fossil chelicerate arthropods.
[2][4][5][6][3] Fossils of the single and type species, A. parva, have been discovered in deposits of the Carboniferous period in Montana, in the United States.
[3] Anderella is also one of the few synziphosurine genera with fossil showing evidence of appendages, but the details are obscure due to their poor preservation.
[1][3] The prosoma of Anderella possess a suboval carapace slightly longer than the externally 10-segmented opisthosoma (excluding telson).
[1] The last 3 opisthosomal segments (which forming the postabdomen) are longer and lacking pleurae (lateral extensions).
