Post 93 & 94.

Both Horaga albimacula & chalcedonyx occur in Singapore.Both have white forelegs.
They were included as one species in the past but are now separated.

The main difference is on the upperside.

H. albimacula : FW white patch does not extend below vein 2; wings without basal blue scaling.

H. chalcedonyx : FW white patch extend halfway below vein 2. wings with basal blue scalings.

With too few examples of the local ssp. it is diificult to separate the two.

By comparing with Les' set specimen of H. chalcedonyx yours looks like H. albimacula.

Sunny, Yours looks like H. chalcedonyx.

TL Seow : Cheers.
