Gratidiini Explained

The Gratidiini are a tribe of stick insects based on the type genus Clonaria (as an old synonym Gratidia Stål, 1875) and first used by Cliquennois in 2005.^[1] Genera are known to be distributed in: Africa, Europe, temperate and tropical Asia and various Pacific Islands.

This tribe was previously placed in the Pachymorphinae, but the current consensus (2022) is that it is better placed in the Bacilloidea: either in the family Bacillidae or a proposed new family "Gratidiidae".^[2]
