Are these all Horaga syrinx?

[Psyche]

It looks like you have found another new species.

The wingshape indicates it is a female.
The underside is rather like H. syrinx except for the marginal spots in space 3 & 4. (poor 0r absent in syrinx); white forelegs.

Both H. syrinx & onyx have extensive blue in both sexes.

H. albimacula & chalcedonyx are both small species initially considered conspecific.

H. albimacula :upperside brown without basal blue scales (all continental forms)
: FW white spot do not extend below vein 2 (or barely); on the underside rapidly fades off below vein 2.

H. chalcedonyx.: Upperisde brown with blue basal scaling.
Upperside FW white spot extends below vein 2.
On the underside it also extend as a slightly narrower band below vein 2.

So this specimen matches H. chalcedonyx quite well.
