The overall classification based on characteristics of the genitalia and the geographic distribution of family groups are as follows:

The genus †Promastacoides was originally considered a privative Eumastacoidea taxon by Kevan and& Wighton (1981), subsequent authors have consistently found it to be a Susumaniidae stick insect.[3]
