Aeromachus jhora jhora. ;Antennal club with a more gradual thickening ; FW cilia usually chequered.

1 Aeromachus pygmaeus. Correction: A. dubius impha.
Antennal club abruptly thicken, the end rounded without a point.FW cilia generally dark, not chequered.
2 & 3 . Aeromachus dubious impha. (Zooming into image 3 shows club with tip )
Antennal club somewhat abruptly thicken but ending with a tip. FW cilia usually chequered.

Thank you so much for going into detail, sir. I'm still stuck with Post 65. #1 Aeromachus pygmaeus though and some of such individuals. The FW cilia isn't checkered but the antennae is long and gradual. In that particular pic, the antennae isn't well focused, my bad. Here's a more proper one of the same individual. I agree with you on Aeromachus dubious impha, and since both were flying around together and were taken on same date, I think #1 Aeromachus pygmaeus is also Aeromachus dubious impha. I have some specimens avaialbe but sadly I cannot dissect because I don't have the miscroscope. I'll let you know what comes out when I dissect it one day. Thank you for everything again.

Concur with you that Post 65 #1 is A. dubius impha.
The antennal club is definitely elongate.
There is very little difference between A. jhora & dubius impha.
What the description meant is in A. jhora the antennal club is longer, more gradual, becoming thickest, than narrowing forward before the apiculus is joined.
AS seen here.

In A. dubius impha, the antennal club at its thickest is joined by the apiculus, thus the club is shorter with a more abrupt appearance.

Wow, thank you sir! That really simplifies it. And A. pygmaeus will always have antenna without apiculus, right? At all instances?

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.
