Diagnosis: O. viraktamthi   sp. n. can be distinguished from other Orosius by: pygofer, aedeagus and spine at base of anal tube. pygofer significantly pointed and slightly curved posteriorly ( Fig. 44 View FIGURES 33–44 ); shafts of aedeagus abruptly narrower preapically ( Figs 30–31 View FIGURES 21–32 ); spine at base of anal tube moderately long and slightly regularly curved ( Fig. 54 View FIGURES 45–56 ).
