This Complex contains 9 previously described species. Seven species of the Complex are distributed without doubt in the Oriental Region ( Fig. 1 ). Two Nepalese species, R. steinmanni at an elevation of 1850 m and R. kisszoltani at 2835 m ( KISS 2013 ), occur only in HOFFMANN’s (2001) transition zone.
