Singillatus singularis (Nielson): Nielson 2015: 54.

Remarks. No specimens of this species were studied. Nielson (1991) adequately described and illustrated the species based on male specimens collected from Assam. This species is similar to O. indica but can be easily distinguished by the long caudoventral spine-like process on the pygofer (Fig. 41 A), the position of the subapical process of the aedeagal shaft (Figs. 43 C–D) and by the small apical spine on the subgenital plate (Fig. 43 B).
