Is this Athyma abiasa (Abnormal Sergeant)?

[Tai LA]

I checked CP4 Plate 26 No 5 ...the only one with the dot on top of the large white spot (pl see my red highlights on the open wing shot). Enclosed also the under surface wing shot

It is Athyma reta.
The small spot is not important.

The main ID points are 1. the FW cell-bar is twice constricted & well separated from the triangular cell end spot & 2., postdiscal spot 2(large & round)is close to the spots below it.

Wow! I thought every single dot or spot counts! Thanks for your in depth ID info, Dr Seow!

[atronox]

In live specimens of A. abiasa, the forewing bases and discal areas have a distinctive greenish "veiny" pattern

Clarification.
There are some name changes due to the realisation several species were mixed up.
The small spot is of use to differentiate these closedly allied species.

I wasn't aware of these changes until now. Interesting.

Athyma clerica shouldn't be found on Borneo because that's where matanga(formerly abiasa matanga) was described from

According to Yutaka it does but I am not sure.Type location of taxon clerica is Malacca.

A. matanga (after Mt Matang)would occur in Borneo as the nominate ssp matanga.

Wow! Thanks a lot for the information, Dr Seow!

Just a follow up on this thread on this species which we believe is Athyma clerica clerica from Mahua Waterfall in Sabah.

The Yutaka website have been updated.

This should be A. matanga. Correction; Athyma clerica.

The two species A. clerica & matanga are very similar.
Both now occur in Thaialnd, Malaya, Sumatra & Borneo.

A. clerica FW without extra greyish spot although there diffuse shading.(Wrong premise)
Subapical costal spot relatively small.

A. matanga.. FW with extra greyish spots, particularly just beyond the cellend spot(Wrong premise).
FW subapical band's costa spot relatively large.

Correction.

This is correct as Athyma clerica.

The name said it all.
In A. matanga the cellstreak is incomplete & broken.

In A. clerica the cellstreak is entire.



TL. Seow: Cheers.

[Commander]

Thanks again! I didn't notice that in the field shots in your references as well. After you pointed that feature out, it's more obvious. But the specimens in Inayoshi's references are hard to separate. The cell streaks in both species seem quite similar?

Inayoshi's set specimens are rather low-res which make the cellstreaks look similar & entire.
It is only when I took a 2nd look at all the fieldshots including those at the bottom of the webpage that it make sense.
