Yimnashana is a genus of longhorn beetles of the subfamily Lamiinae.

[1] In 2016, the genus Tinkhamia was reduced to a subgenus of Yimnashana.

The authors considered that Tinkhamia was very closely related to Yimnashana, differing only in having completely divided eyes and even more reduced wings.

A phylogenetic analysis based on similarity measures showed that when treated as separate, Tinkhamia and Yimnashana were the most closely related genera within the tribe Gyaritini.

[2] As of October 2023[update], BioLib accepted two subgenera, containing seven species in total.
