Usually, I recognize Helina reversio by these main criteria :
(1) - pra short
(2) - eyes bare
(3) - a pd on basal part of hind tibia
(4) - ks 2:2
(5) - legs black, but apices of femora and tibiae reddish colored.
(6) - abdomen spotted.

I can't confirm points 3 & 4, and you say you can't see any spots on abdomen, so I'm doubting.
