Charmus is a genus of buthid scorpions native to India and Sri Lanka.

In 1917, Birula proposed a new family Vaejovidae and a new sub-family Charminae for the species by ignoring the publications of both Pocock and Kraepelin.

However Birula's work was poorly known due to being Russian, until 1965 when an English version was prepared by the Israel Program for Scientific Translations.

In the meantime, he also made reference to several specimens deposited in the Muséum National d’Histoire Naturelle, Paris and named a new species Charmus annulipes with the work done by Eugène Simon around 1899/1900.

Third and fourth legs comprised with well developed long tibial spurs, whereas the first and second tarsomeres are with ventral setae.
