Arhopala major major male
Male (abdominal tip truncated)
Keys 1, 7, 8, 9, 23, (skip 24) 45, 55, 59, 63, 71, 72, skip 73 (borneo spp), 74, 75(A amphimuta) or 76 (A major).
In A amphimuta the two outer spots in space 7 and spot 6 are usually roughly the same size. InA. major the middle(discal) spot in space 7 is about 2/3 or less that of spot 6. However, some amphimuta may overlaps that of major in that the middle spot in space 7 is variable in size and may be relatively small.
The icing on the cake is that the upperside of this male shows the broad brown border of A. major.
This is an excellent pic of A. major to keep for reference.
