Hi Doctor Seow,
I was browsing through Taenaris horsfieldii in C&P5 and decide to take a look online. All online records i found of photographs are found in Borneo, though C&P5 mentions its found in johore primary rainforest. Do you happen to know of any records of specimen collected in Johor? I find this to be interesting as I like this genus a lot, and know Taenaris horsfieldii is the only representative of its genus in Malaysia. Johor has been going through quite some development, so i was curious to know if there might be anywhere specific to take a look in the future as a consideration
Skipping regards

This is a rarity that was first recorded from Singapore.
With Melanocyma faunula , it is a slow, high flying Amathusiid that is likely to be distasteful.
In the Papuan region, Taenaris forms mimetic complexes with Delias species.
This belongs to a group of Sundanian butterflies that have a remnant population largely in Johor.
Others include Rapala cowani, Lexias bangkana (prev. as L. cyanipardus), Mycalesis horsfieldi, Salanoemia shigeru.
This specimen was taken by Wicky Fleming in 1974.

As it has also been recorded from Pahang, it would indicate it is present in the vast Endau-Rompin forest bordering Pahang & Johor.
Hardly anyone goes there to photograph butterflies.
Much negative observations made in the Panti forest suggest it is not present there.
TL Seow: Cheers.
PS . Singapore specimen.

Shoud be correct as P. flavia.
Three species are similar in the following features.
FW subapical spots 6 & 7 are aligned nearly parallel to the termen (outer margin).
A line thru them ends on the lower margin (dorsum).
HW veins are shaded yellow/orange on both sides.
In P. flaviaq the opalescent streak in space 5 is absent or obscure.
In the other two species it is prominent.
P. flavia.
UnF without opalescent streak in space 5 or weakly.

Note Yutaka have withdrawn this species from the Thai checklist.
Both P helena & natuna have broader yellow in the male.
UnF have a prominent opalescent streak in space 5.
P. helena is stated to have a small hyaline spot in space 5 while P. natuna does not.
