Is this Athyma abiasa (Abnormal Sergeant)?

[Psyche]

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

Attachment 28256

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.

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.

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.
