Remarks.
Originally described from at least two specimens (
syntype
) with the following data: “E. Himalayas; Kurseong, and Ghumti, Darjiling Distr. (F.H. Gravely)”.
O. connexa
and
O. compressa
have an overlapping distribution and have been collected together. It is difficult to differentiate them without dissection.
