Arhopala moorei - check ID

[DaveChiangMai]

This individual is not that well marked, but appears to have the correct alignment of spots for Arhopala moorei.
Images of well-marked individuals seem rare to non-existent.
Comments on ID appreciated please.

Most likely Arhopala amphimuta.

The smaller members of the amphimuta group are very difficult to id in fieldshots.

The larger members FW 21-23mm have UnF spot 2 & 3 in line.
UnH spot 6 is relatively small & far from the cellend bar, covering less than half the gap between spot 5 & cellend bar.

eg A. amphimuta, major, moolaiana & norda.


In A muta & moorei FW 17- 19mm, UnF spot 2 & 3 are not inline.
UnH spot 6 is larger & covers more than half the gap between spot 5 & cellend bar.

A. metamuta FW 18-19mm is in between ,with FW spot 2 & 3 in line & Unh spot 6 covering more than half the gap stated.

Examples
A. amphimuta & major.

It does not seem possible to separate A. muta from moorei from the underside.

The FW is raised high enough to see spot 3 clearly (squarish).
The very edge of spot 2 can be seen & this is in line with that of spot 3.

This prove that it is a large species.
UnH spot 6 being small & far from the cellend also confirm this.
The tornal white spot is absent ( could be abraded).
The V spot is very well-formed.

The appearrance is very much Arhopala amphimuta.

Many thanks. Yes, I would agree Arhopala amphimuta looks more likely based on the descriptions and diagrams.
