Thank you so much sir. But it is very difficult to id for some invididuals. Like the below one. I am not able to figure out whether it is dohertyi or sambara. However I am more confident about this to be sambara.
The problem is with 1 actually.
Is 1 wsf S. dohertyi or colud it be dsf S. sambara.
6 is female (note abdominal end) Parnara bada.
The spots are as in Parnara & the antenna is short with a thick club.
The presence of HW spot 6 should exclude P. ganga. P. bada. https://www.ifoundbutterflies.org/me...119c8e50-1.jpg
I am trying to make some sense of Seseria but it is rather tough.
There are a lot of coflicting images.
Evans, 1949 provides description of the two species. But unfortunately he did not mention about the variation in the DSF S. sambara.
Evans quoted:
Seseria dohertyi: Abdomen above white corresponding with the hindwing band, base and tip brown. Uph white area broader than in sambara and unh the discal spots are separated
from the dark border, particularly in the DSF. Upf the spot in space ib connected to the dorsum by a white area wider than the spot.
Seseria sambara: Abdomen centrally white, as in dohertyi, but in female tends to be striped. In WSF the white area uph is somewhat sullied and narrower than in dohertyi. Upf the white spot in space ib is narrower and outwardly excavate: the connecting white bar to the dorsum is obscure in the WSF.
1 seems to qualify the characters for dohertyi mentioned by Evans.
However I also find some images that perhaps be S. dohertyi (probably/or DSF sambara as you mentioned).
Seseria sambara.
HW outer brown zone much wider than the white band in both wsf & dsf.
HW the two black spots in space 7 set close together so that white area is about one spot width.
FW with weaker white streak in space 1a in dsf, nearly obsolete in wsf.
Seseria dohertyi.
HW outer brown zone less wide than the white band in dsf, about equal in wsf.
HW twin black spot in space 7 set farther apart so the white area is about 1.5 to 2. 5 spot width.
FW with strong white streak in space 1a in dsf, less defined in wsf.
