That is a lovely young female - probably around 5 or 6 months old. No bulge, rostral process indicates female and she has that typical orange colouration with a hue of green/blue. She's not yet sexually mature from my assessment and is coloured EXACTLY the way my young Ambilobes are BUT with the females, it's basically impossible to know what locale they are unless you know the lineage.
Ensure she has access to a lay bin in the future when her colours change and you notice her putting on weight.
