Misumessus is a genus of North American and Caribbean crab spiders first described by Nathan Banks in 1904.

They look similar to members of Misumena, but are much spinier.

[1] It was considered a monotypic genus until 2017,[2] but its taxonomic standing has been debated throughout the 20th century, first as a synonym of Misumenops,[3] then later as its subgenus.

[4] It was raised to genus status in 2008,[5] but has still been confused with similar genera, some of which were only known by character descriptions made by Eugène Simon nearly fifty years earlier.

[5] As of February 2019[update] it contains seven species:[6] This Thomisidae-related article is a stub.
