I don't think it can be D. vidura. According to funet.fi, there are two species of Dacalana on Borneo, both endemic. D. lowii of the vidura group, and D. sannio of the cotys group.

The difference between the two groups is that the vidura group males have a brand on the forewings, and those of the cotys group do not.

This is likely to remain a 'Dacalana sp. indet'. I do not think anyone of us managed an upperside shot of it.

It can't be lowii as there's a white band and it also cannot be sannio coz the yellow tornal spot is too big.

Interesting, thanks Aaron. Funet is behind with info in some cases, this must be one of them.

Is this ok for ID ?

Here is an Idmon species, but I can not tell which one. According to C&P4, there are two similar species on Borneo, I. obliquans and I. latifascia, which has a wider orange-red band. I have nothing to compare mine to, so am at a loss. Any help, please!

Yes, in part! One of the vidura group. Anyone got up to date info ?

1 Arhopala atosia.
Key line 46, 50, 52, 53/54 (atosia/lurida) Dull surface suggest it should be atosia.

2 Matapa spp. very worn , abraded surface. ( correction: this is Gangara lebadea)
Note no hyaline spots, red eyes; tornal cilia grey. Forewing underside does not match shading in Zela.probably also badly abraded.

3 Dacalana sinhara
With upperside known, note dark stria ends into orange spot. In vidura, orange spot smaller and dark stria runs above it.

Amazing you have 3 Pierid species.

1 Delias species.
Looks like the Indian species eucharis except the submarginal spots are not red.

2 Cepora species. (confirmation : this is Cepora pactolicus)
Could this be the Bornean subspecies montana of C. iudith or the new one called C. pactolicus.

3 Prioneris cornelia
This should be correct.

The 3 Pierids are very interesting.

The first two should be Catopsilia pomona.

The 3rd is very unsual. The upperside have an orange band as in Ixias pyrene, but the underside is unmarked and yellow.
Probably the Bornean subspecies called undatus.

Since the same subspecies I. obliquans obliquans occur in Borneo as on the mainland, and this one have the orange band almost twice as wide, this should be I. latifascia.

I agree that No1. is a Delias species, when on earth did you see it and where!!!!!!!! and why did you not give me a shout!!!!!!!!!!!!!!! It is [I]Delias singapura indistincta.[/I ] There is a small difference in the photo from the specimen in my collection in the amount of yellow on the hindwing in my specimen, but I think that this is probably just a minor variation, everything else fits perfectly.
