Essentially so.
The description for A. pygmaeus read.
Antenna with the tip blunt, the club straight without a well-defined apiculus.The antenna is short, less than 1/2 the length of the costa.
Also A. pygmaeus is very small FW < 10mm . A set specimen is half the size of A. jhora.


The great difficulty is between A. jhora & dubius.
The club in jhora is more cylindrical & that in dubius more bulbous (bulging) but the difference appear slight.

The UnH in A. dubius is not constant.
SOme example have reduced HW spots & resembles ssp dubius.
eg. ssp impha from Thailand marked as in ssp dubius.

Others not so.

If you have specimens you could check on the antennal features.
