The females of Q. singularis and monteithi only differs slightly.
In Q. singularis the FW cellspot (part of the band) is wider and rectangular.
In Q. monteithi the FW cellspot is squarish.

This is one of those intriquing problematic case. Amathusia.png
The main problem is thec difference between A. phidippus and A. friderici.
Both would have become common; A. phidippus hostplant Coconut, and A. friderici hostplant Oilpalm.
The important thing to look for is in the 4th dark band.
1. A. phidippus typically have the 4th dark band usually wider than the 3rd band.
The band tapers upward reaching the costa without rounding off.
The sides are typically intact and regular, barely notched.
The upperside in the male is typically dull and diffusely marked.
A. friderici is stated to have bicolored hair tufts, upper hairs dark and lower hair buff.
It is very difficult to determine this in photos and very confusing.
It is also possible the reference text have got this in reverse ie, upper should be buff, and lower ones dark.
Tentative ID.A. friderici based on upperside more orange colour and UnH 4th band upper end more rounded off.

Arhopala muta or moorei.
The males of the two can only be separated by the uppersides.
A. moorei have both wings the same blue.
In A muta male, the HW is lighter but not to the extent of A. metamuta.
Similar.
A. portunus.
1. HW spot 6 as in A sarrastes.
2. Submarginal spots not black and white or weakly in the female.
3. FW postdiscal spots not dislocated and parallel to the outer margin. https://yutaka.it-n.jp/lyc2/80370010.html
Neptis sedata and leucoporos practically have identical marking.
They both have FW postdiscal spot 3 shifted out and close to the adjacent submarginal spot.
The lowest postdiscal spot on the FW lower margin is also very small.
Neptis have a white band across the abdomen connecting the discal bands on the HWs.
There is trace of this white band on the abdomen here.
