Neptis species

[DJHiker]

In my photo collection there are a number of Neptis specimen from Sri Lanka, Thailand and Vietnam that I tentatively labeled as Neptis hylas.
However, I doubt if they are all correctly identified, in particular the one (no. 4) seen in Vietnam.
Would very much appreciate your opinion.

4. Neptis sp.

Thanks in advance.
Cheers,

The 3 species in which the FW cell bar has a fracture line or is broken are Neptis hylas ,N. sappho & Phaedyma columella.

P. collumella may be ID'ed by the FW spot on the lower margin(dorsum) being large with a small spot above it (in space 1b).

Neptis hylas & sappho are very similar & confusing.


Neptis sappho :FW with the four postdiscal spots narrower & more rounded in particular spot 1b is always rounded.
On the underside FW N sappho have the veins black but this is difficult to see in the field shot & unreliable.
N. sappho is widespread in subtropical & temperate regions , into southern Europe.

Neptis hylas; FW with the four postdiscal spots rather wide (ie horizontally elongate) FW spot 1b oblong or oval.
Underside FW with veins not black but hard to judge.
Sri Lanka.
