Unidentified species from Nakhon Si Thammarat, Thailand

[Painted Jezebel]

These are my remaining species for which I am uncomfortable about their identification. First 3 from Krung Ching, the last two are from Khao Ramrom (c.1000m).

1) Dacalana sp. I suspect D. vidura but not sure.
2) Halpe sp. I think this will not be identifiable, most Halpe need genitalia inspection.
3) Arhopala sp. I believe this belongs to the alea subgroup, always difficult.
4) Something common I.m sure, but I get brain freeze every time I try to id it!
5) Arhopala sp. Every time I use the keys, I come to A. agesilaus, but I am not certain.

1. Dacalana vidura is probably right.
The HW orange patch does not obliterate the black striae.

D. sinhara .This can be very confusing.
As stated in the key the orange covers the black striae in space 2 & part of space 1b.
Typical Malaya.

However there are many ID'ed as sinhara by the longer brand above but on the underside the orange does not cover the black striae.

2. Halpe insignis. The white HW cilia variable.

3. Arhopala , alea subgroup. best quess is the commonest A. sublustris.

4.male Nacaduba kurava euplea. broad submarginal spots.

5. Arhopala epimuta female. FW spot 4 is dislocated & shifted outwards from spots 3 & 5, ruling out A. agesilaus.

Thank you very much indeed.

[Painted Jezebel]

Sorry, I forgot one!

This is a female Poritia sp. from Khao Ramron (c.1000m). We found 3 species of Poritia there, P. hewitsonii, erycindoides and philota.

Post 4.

Should be the female P. philota.
The orange is much reduced compared to the female erycinoides, variable, & may even be obsolete f-lugubris.

TL Seow:Cheers.

[Painted Jezebel]

Thank you. That was what I suspected. There were some very strongly orange marked female P. erycinoides around, that looked as if they could have been Curetis spp, except for their undersides.

A possible difference between Dacalana vidura & sinhara may be this since the brand size is confusing.

Underside FW black striae nearer termen than cellend in D. vidura.

Underside FW black striae about midway between termen & cellend in D. sinhara.

However this suggest the link below is D. vidura instead (Thailand)

Could Yutaka's images may be D. sinhara? It also looks similar to A. Cassidy's example.

This table, from our friend Inayoshi Yutaka, could be of some help:

Thanks Antonio, for the images provided.
Very interesting but no nearer the solution.

Both D. penincilligera & burmana can be discounted because of their small delineated orange ring.

The ?sinhara from Chiangmai looks like a form of D. peninicilligera with the defined orange ring.

The sinhara from Ranong looks correct although the underside black striae are not obliterated.
The upperside HW also have the outer part of space 7 with some shaded blue as in correct examples of sinhara.

The vidura from Yala is interesting.
The male on the left has a large brand/hair tuft & the underside black striae partly erased by the orange as for sinhara, but HW space 7 above is not marked with blue.
The male on the right looks typically vidura.

The whole picture is still rather confusing.

C&P4 states for Peninsular Malaysia vidura is fairly common while sinhara is much rarer.

TL Seow:Cheers.

Not from Nakhon Si Thammarat but can be interesting in this context this Dacalana cremera ricardi from Than To (Yala)

According to the key of C&P4 this would be Dacalana sinhara for peninsular Malaysia .
The black striae in space 2 & 1b are faded & partly erased by the orange.
The key states underside hindwing orange area more or less obliterates the striae in space 2 & upper part of space 1b (ie in the set position).

For vidura, underside hindwing orange area not overlapping the striae in space 2 & 1b.
This is as for Les' shot where the black striae are equally dark .
