Isma bononia?

[Angiud]

Thank you Dr. Seow for your help.

I know Isma are not easy to separate.

I will go again soon over there and I hope to see them again and try to get better shots, of the upperside too.

Sorry, I have not joined in the discussion before, I have been in N. Thailand.

It is interesting to note that Kimura in Butterflies of Thailand, Volume 1 (2012) contradicts C&P4 regarding the difference between I. bononia and I. bononoides in that he says the spots in the former are yellowish, and those of the latter are almost white. He also states that the only two records (from 1991) of I. bononoides are lacking collecting data and that there are no illustrations, and as such, the species needs to be reconfirmed as present in Thailand.

I did a review on these two species.
Fleming have good upperside & underside of these two species & they support that of C&P4.

These two are distinctive in that the two cellspots (in the male) are in line with the big spot in space 2.
The spots are yellow in bononoides & whitish in bononia.
Moreover the underside colour are quite different ,ferruginous in bononoides , olive/greenish ochre in bononia.

There is no doubt with this I. bononoides.

There is also no doubt with the female I. bononia from Nakhon Si Thammarat; greenish ochre ground, brownish grey abdomen.
However, there is doubt with the male from Taman Negara.
Upperside suggest I. bononia; large cellspots , spot colour ambiguous at best.
The underside is ferruginous & the abdomen is strongly banded (compare with the female).
The male has to be I. bononoides.

Thank you. I will amend the pages accordingly. Was the review published and if so, where? I would like a copy, hopefully I would be able to download it online.

Reviving an old thread for a new dubious record, from Betong, Yala, South Thailand:


Isma sp.


Could it be Isma bonomia?

Post 9.

It is definitely not Isma bononoides .

Female.
Abdomen fully banded .Large upper FW cellspot indicating two large cellspot.
HW medium brown.

It Is the female of Isma damocles. less likely the female of I.guttiliferawhich have the upper cellspot smaller.

I. damocles /Abdomen fully banded; Two large cellspot white. Underside ferruginous. Female have the HW spots usually absent.

Isma guttilifera. similar ; FW spot 2 is more in line with the two cellspot. Underside ferruginous.

Isma bononia. Abdomen not banded beneath; Underside ochreous/golden yellow; FW spots white or whitish.: FW spot2 & 3 with small overlap.
This is correct although the FW spots are buff ?loss of scales . yellow underside & small overlap of FW spot 2 & 3 confirmed ID.
