Ansiea is a genus of crab spiders that was first described by Pekka T. Lehtinen in 2004.[2]
The genus is named in honour of South African arachnologist Dr. Anna (Ansie) Dippenaar-Schoeman for her contributions to the study of African Thomisidae.[3]

Taxonomy
The genus Ansiea was established by Lehtinen in 2004 as part of a taxonomic revision of the Misumenini tribe.[2] The type species, Ansiea tuckeri, was originally described as Misumena tuckeri by Lessert in 1919 and was subsequently placed in Misumenops by Millot in 1942 before being transferred to Misumena by Dippenaar-Schoeman in 1983.[2]
Although originally placed in Misumena, the species of this genus are not closely related to it.[2]

Description
Ansiea species are distinguished by several morphological features.[2] The carapace is exceptionally wide, and the femora, tibiae, and metatarsi of male legs I-II have a reddish-brown distal annulation.[2]
Females are differentiated from other Misumenini by the presence of very long, irregularly coiled, thin insemination ducts in addition to thicker ducts attached directly to the spermathecae.[2] Males are characterized by a cymbial fold opposite to the distal part of the partly fused RTA-ITA (retrolateral tibial apophysis - intermediate tibial apophysis).[2] The tip of the embolus is obtusely rounded and enlarged.[2]
