Yimnashana is a genus of longhorn beetles of the subfamily Lamiinae. The genus Tinkhamia is included as a subgenus.
Taxonomy The genus Yimnashana was established in 1937 by Gressitt. 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.
