The recent observation from Kent Ridge is definitely not A. phidippus. https://static.inaturalist.org/photo...502/large.jpeg
It looks like a female A. perakana.
The FW is not sharp as in the male.
However, there are examples of A friderici from Ubin having the HW 4th band very narrow & broken.
So it is uncertain whether this is A.perakana or friderici.
