Additional material examined. INDIA: UTTARAKHAND: Dehradun, FRI, 1 ♀, 04.xi.2009, coll. F.R. Khan; Almora, Matikhola, 1 ♀, 28.x.2009, coll. F.R. Khan.

Material determined and recorded by Hayat (2008), Begum & Anis (2013) and Fatma et al. (2014) was also examined.

Distribution. India: Jharkand; Rajasthan; Uttarakhand; Uttar Pradesh.

Comments. The original description of O. meerutensis was based on a single female. The holotype is on two slides, one slide with one antenna and one fore wing under a large coverslip, the rest of the body (vertex and left eye broken off; antenna beyond pedicel missing) on the second slide under a small coverslip.

The original description of O. aligarhensis was based on 3 females. The holotype is on a slide under a large coverslip. The two paratypes are on one slide in drops of balsam.

The original description of O. kasimpurensis was based on 3 females. The holotype is on two slides, one slide with antenna and one fore wing under a large coverslip, and the rest of the body (left half of head broken off) on the second slide under a small coverslip. The two paratypes are on one slide bearing the same data as the holotype, but with collection number ‘433’.

Hayat (2008) examined the holotypes of O. meerutensis , O. aligarhensis , and O. kasimpurensis , and considered the three conspecific.
