Distribution.

India.

Etymology.

The new species is named after the type locality, Tehri.

Comparative diagnosis.

The new species is similar to M. orientalis . Apart from the differences given in the key it can be distinguished from M. orientalis by the following characters: antenna slenderer, with 17 flagellomeres (16 flagellomeres in M. orientalis) and hind femur 5.6 × as long as wide, concave dorsally (4.6 × as long as wide and convex dorsally in M. orientalis).
