***Orsima*** is a [genus](/source/Genus) of [jumping spiders](/source/Salticidae) that was first described by [Eugène Louis Simon](/source/Eug%C3%A8ne_Simon) in 1901.[2] As of August 2019 it contains only three species, found only in Africa, [Indonesia](/source/Indonesia), and [Malaysia](/source/Malaysia): *[O. constricta](/source/Orsima_constricta)*, *[O. ichneumon](/source/Orsima_ichneumon)*, and *[O. thaleri](/source/Orsima_thaleri)*.[1] *O. ichneumon* was considered a *[Polyrhachis](/source/Polyrhachis)* [ant mimic](/source/Ant_mimicry) in reverse, but this theory was later dismissed.[3]
