Type Material
Tiwari (2000) - Holotype: worker: INDIA: Meghalaya, East Khasi hills, Pynursla, 6.viii.81, Coll. R. Mathew; Paratypes: 13 workers with the same collection data as the holotype.

Note (Lubertazzi 2018): it is stated in the publication where this description was published that "The present work is based on the material collected and deposited at the Zoological Survery of India, Eastern Regional Station, Shillong, and the Headquarters at Calcutta" with the latter presumably referring to the Zoological Survey of India headquarters. The types of this species can presumably be found in either or both of these collections.
