Allocyclosa is a genus of orb weaver spiders that contains only one species, Allocyclosa bifurca. It was first described in 1887 by McCook under the name Cyrtophora bifurca, and was transferred to its own genus in 1999. It is the only Cyclosa species north of Mexico to have a forked rear tip of the abdomen hence the name bifurca, Latin for "two-pronged". The forked tip of the abdomen, bearing two humps shaped like the letter M, is a defining feature in both males and females, though it is similar to features present in certain Cyrtophora species. Both sexes are a grey-green color, though only females have an area of red on their underside between the epigynum and the spinnerets.
