Arhopala wildeyana top-female, bottom-should be male
I finally managed to figured this one out. One of the great difficulty with Arhopala is that individual variation would render any textbook description inaccurate and what are perceived as stable features unreliable. In this case whether the postdiscal band on the forewing is whole, kinked, or dislocated is inmaterial. Another is the spot in space 6 on the hindwing; this may be fully or partially under spot 7, and likewise fully or partially astride the cellend and spot 5.
The most noticeable feature is that the spots are rather large for the butterfly. Postdiscal spots 4 & 5 are fully conjoined or almost so. The 3 discal spots are large with the lowest in space 1 quadrate. The submarginal spots on the hindwing are either dome-shaped or pyramidal. Closest to Fleming's L236B Un. In the text, A. wildeyana is stated to be not uncommon in Singapore.
