Mayriella ebbei

This is the southernmost species of Mayriella and occurs in generally drier sites compared to other species. Although widely distributed it shows minimal geographic variation in the characters examined during this study. Nests occur in soil in the open or under stones or other objects on the ground, and in rotten wood.

Identification
This species can be separated from others in this genus by the presence of numerous erect hairs on the gaster. It shares the shape of the outer margins of the postpetiole with Mayriella spinosior, but differs from this species in the shape of the petiolar node and in having more than four erect hairs on the postpetiole.
