Key to Vietnamese Leptanillinae Genera

AntWiki: The Ants --- Online

This key is based on Eguchi et al. (2014), with taxonomic updates provided by Griebenow (2024). It was originally modified from Borowiec et al. (2011) and Xu (2012).

Opamyrma is included in the Key to Vietnamese Amblyoponinae Genera. This genus was moved from the Amblyoponinae to Leptanillinae after this key was published.

This key has been superseded by Keys to Leptanillinae (but it has been updated to reflect the current taxonomy of the subfamily, with the exception of the inclusion of Opamyrma).
