A line thru subapical spots 6 & 7 is directed to the termen.
FW space 5 is black, without an opalescent streak.
HW vein 8 is double-sided scaled orange, iamge 1 and 3. Best viewed with smartphone & zoom.
Antennal shaft is partially white.
Vein stripes are reddish when fresh.

FW spot 9 in line with the rest and often as wide as spot 6 below it.
Costal spot 10 always in line with the cellend bar and often as wide.
FW postdiscal band is partially dilocated at vein 4 (ie below spot 4) 2nd image.Postdiscal spot 3 may be reduced.
Typical wide spots form.

Forms with narrow spots.

A. cleander is very similar.
FW spot 9 in line with the rest but never wider.
FW postdiscal band not dislocated at vein 4.

Hypolycaena phemis.
H. phemis was placed under H. amabilis in C&P4.
Eliot later provide a key for the separation of H. amabilis and phemis from H. merguia.
In H. meguia HW marginal spot 2 is edged in orange on its inner/lower margin. This represent vein 2.
The black spot in space 1a have silver dcaling but this is impossible to see.

https://www.gbif.org/occurrence/2847202014
Both H amabilis & phemis lack this orange edging on marginal spot 2 ( nor the silver scaling on spot 1a.)
H. amabilis .
HW always with a black marginal spot 6, HW apex whitish.

H. phemis.
HW without a marginal spot 6 or only vaquely so
HW apex is tinged orange.
(Note in the past under H. amabilis.)

There are more examples of H. phemis than amabilis, indicating it is probably the commoner species.

Male Lethe mekara.
The white band and the dark fascia which expands along the FW costa is that of the male Lethe mekara.
