I did'nt realise there is a ssp of D. ravindra which is also similar.

Firstly D. theda is out as the HW postdiscal spot 6(hollow) & spot 7 (solid) are well out of line.
The lower postdiscal bands are also long.

The ssp (un-named) of D. ravindra is also found in S. Vietnam.

The important features.
1.In D. ravindra the HW postdiscal spot 6 & 7 are perfectly aligned forming a uniform column.
2.The lower postdiscal spots below are more curvy & U-shaped.
3.The FW discal band tend to be undulate.
The 1st feature is particularly constant ,as seen in other ssp.

In D. rufotaenia vietnamica.
1. HW postdiscal spots 6 & 7are slightly out of line, with spot 7 shifted inwards.
2. The rest of the postdiscal spots are less curvy.
3. FW discal band is more or less straight.
This individual matches the female from Dong Nai well.

appears that whether the bands are ssolid or 'hollow' depends on the subspecies in most species.
