I have a gravid female of Pangio cuneovirgata, and last weekend the big luck to find two other loaches of this species (in a tank full of P. kuhlii). I can't say if there was at least one male, but hope dies last.

I tried some close-ups and think that one of the new P. cuneovirgata could be a male, the pectoral looks more a male than a female. But this isn't confirmed at this time.
Here two pics (from today) of the female.
