It is Endemic to the Western Ghats
The species is very closely related to O. nilgiriensis, and apart from the appendages the only reliable character by which to distinguish them is the pointed lower end of the antehumeral
stripe in O.acinaces and the absence of occipital spines in the female. O.acinaces is a far more static insect than O.nilgiriensis, which, as has been noted above, exhibits considerable variation.
