Rotastruma is a small genus of arboreal ants in the subfamily Myrmicinae.

[2] Its two species are known from the Oriental region: the type species Rotastruma recava is known from the Bukit Timah Nature Reserve, Singapore, and Rotastruma stenoceps is known from Guangdong, China.

[3] Little is known about the genus, and like most other arboreal ants, their biology remains unknown.

However, they seem to have affinities with Paratopula and Romblonella.
