Two species are very similar.
They are still much confused.

This is a common species next after A. unicolor.
FW postdiscal band dislocated in the middle.
HW spot 6 just under spot 7.
All spots are variable.

Allotinus leogoron
The 2nd species is very rare .
FW band with a mid-dislocation & HW spot 6 is under spot 7.
Male upperside with a broader brand.
It differs mainly in that the underside ground colour is whiter & the markings darker giving it a better contrast.
Female HW teeth slightly narrower but impossible to be certain in fieldshots.

There is much confusion.
Otsuka's Bornean Lycaenids give good comparisons L49 & L50.

These IDed as A. horsfieldi are probably A. leogoron.
