Yes, the orange tipped antennae are odd! I have specimens taken there that are typical hypomuta, with the small spot at base of space 6, and their antennae show no sign of orange.

Only two Arhopala from me where I am having difficulty.

LD3) Using the keys, this comes out as A. agesilaus, but I could have gone wrong at no. 46!
LD4) Again, to me, this comes out to me as either A. amphimuta or A. baluensis. It was quite small.

Corrections greatly accepted.

Your LD3 (FW spot 4 partially shifted out) is the same as Antonio's A. hypomuta which I feel is correct as C&P4 practically includes the Bornean species in case they turn up in Malaya. Note opposite antenna tip have the same orangey colour.

LD4. This probably A. baluensis if it is small as amphimuta is medium sized.
The shape of spot 7 is unusual (?abnormal) & the metalmark is different.

The Bornean amphimuta is similar to mainland form.

PS. Female baluensis from Brunei. Metal mark more ?band-like.

Post 9.

Mycalesis . Not sure what the difference is between anapita & patiana undersides. Even the underside of fusca can be identical.

Jamides virgulatus. FW postdiscal band completely dislocated below (vein 4, space 3) & partially above (vein 6); costal white dashes.
HW basal band intact; orange almost covering stria above it.

Oriens gola.

Post 10.

Eurema nicevillei nicevillei. nos. of spots variable.
2 allied species present, but in E. tominia, spots always scanty & cellend bars obsolete or almost so.

Isma ?umbrosa male. Very confusing.
FW large upper cellspot ; spot 3 & 4 do not overlap. Underside ochreous; abdomen not banded ; antennal club large white patch.

Oriens gola.

Your LD3 (FW spot 4 partially shifted out)

So I did go wrong at 46. I did not think it was sufficiently shifted. Oh well!

Hypolimnas bolina ? ssp. labuana.
Too variable.

Dacalana vidura.
This & the much rarer D. sinhara have been easily confused.
In D. sinhara the black striae are obliterated by the orange patch in space 2 & part of space 1b.

Dacalana sinhara. Note black striae obliterated at orange patch.

Two dedicated sites in which the images of D. vidura have been captioned as D. sinhara. Note striae intact beside orange patch.

Lamproptera curius. Black bands broad & uppermost window reduced to a small spot.

Arhopala hypomuta.
Aberrant individual with very small postdiscal spots, but FW spot 4 dislocated HW spot 6 nearer 5; antennal tip orangey.

Post 12.

Allotinus horsfieldi. HW postdiscal spot 6 beneath potsdiscal spot 7; buffy ground & poor contrast.
A. leogoron is similar but contrast between dark markings & whiter ground strong.

Arhopala borneensis probably.
A. trogon & stinga have strongly purple-washed undersides.
The black spots of A. aurea are flattened, in particular the tornal one is rather poor & very small.
Only image of A. borneensis.

Curetis tagalica, most likely. Can be diificult to separate tagalica & regula in some examples.
C. tagalica have the HW lunulate mark in space 6 more deeply - set against marks 5 & 7; FW marks 4 & 5 tends to jut out more (ie. band more irregular).
C. regula from Brunei & Malaya (your own)

Simiskina pharyge. Distinctive marginal metallic green.

Some species you will recognise, but different subspecies:

LD5) You may have a superbly delicious Semanga, but this one is doubly superb! Semanga superba superba (Red-Edge). New to Danum.
LD6) Zemeros emesoides eso (Malay Punchinello)
LD7) Erites argentina argentina (Eyed Cyclops)
LD8) Junonia iphita viridis (Singapore- Chocolate Soldier, Thailand- Chocolate Pansy). A particularly well marked subspecies.
LD9) Halpe ormenes vistula (Dark Banded Ace). New to Danum.
LD10) Charaxes solon echo (Black Rajah). Same ssp. as Singapore. New to Danum.

Dacalana vidura.
This & the much rarer D. sinhara have been easily confused.
In D. sinhara the black striae are obliterated by the orange patch in space 2 & part of space 1b.

I have old references for Borneo. It only shows two Dacalana species on the island, D. lowii and D. sannio. Has D. vidura now been found there? Unfortunately, I only had access to the Butterflies of Borneo at Danum, and then only for the Lycaenidae and Hesperiidae.

I'm updating the Research Centres records to include our finds on our visits in 2010 and 2013, D. vidura is currently not on their list.

It is possible that the Curetis depicted in this link below is C. tagalica.
This is because the upperside matched that of C. tagalica labuana, the ssp in Borneo.
In C. regula the border on the HW & the FW tornus is almost a thread, & there is no subspecies for this species.(see pic & key C&P4)

This makes it more likely that the post 12 Sunbeam is Curetis tagalica.
The indentation of the band in HW space 6 can be very shallow as shown in the example from Muane Chong, Ranong, male.
