Mickelomyrme yunnanensis was one of the most commonly encountered mutillids in Southeast Asia; we examined nearly 100 ♀ from China , Laos , Thailand , and Vietnam . We could not find any significant differences between the description of M. pusillaeformis by Hammer and that of M. yunnanensis by Lelej. The type locality of M. pusillaeformis “Mergui , Myanmar ”, is geographically close to many localities where M. yunnanensis females were collected. We therefore consider M. yunnanensis as a junior synonym of M. pusillaeformis , comb. nov. Although the authors previously thought this species belonged to Mickelomyrme , it was maintained as Smicromyrme pusillaeformis in Okayasu et al . (2018) , because that was not the appropriate forum for publishing the new synonymy and combination.
