Pyroneura derna, still around in Singapore.

[Psyche]

Pyroneura derna is considered extinct in Singapore according to C&P4.
It is very similar to P. latoia.

Pyroneura latoia.
1. FW space 5 with a narrow silvery streak (variable)
2. A line thru the 2 subapical spot is usually directed to the lower margin(dorsum).
3. HW vein 8(highest) scaled orange/yellow slightly more basally ( mostly lower margin. Corrected ).

Oops here!

The skipper in the blog looks to be correctly P. latoia.
It is very worn but there is too much whiteness in FW space 5 indicating there is likely a silver streak there.
The other two features, FW subapical spots & HW vein 8 scaling are subjected to individual variations.
