Goniurosaurus luii? hainanensis? lictenfelderi? Can anybody help?

Hi i have had my goniurosaurus pair about 8 months i was sold them as chinese cave geckos but without latin name. They were kept at room temp in shop as they seem to prefer lower temps and not too dry so i mist the viv. I replicated the conditions and they were fine for a few months not really liking mealworms but eating crickets and wax worms. I have had trouble with the female. The male has always looked healthy and eaten once they settled in. The female was another story. She does not eat very much i have seen her eat but not often. She has not been right for a while just seams very lethargic and lacking of energy. They were mating in shop but i have not seen it however i discovered her with bite mark on her back hip and neck the other day so have seperated them so she is not harrased at the moment, and to monitor what she is eating. i have not put in crickets as she is not in good condition just put in wax worms she has not touched them or even really moved, in about 5 days. I am wondering if she is a lot older then the male. I also think there is the posibility they are slightly different sub species He is very dark where she is a lot lighter purple and has a more blotchy pattern. Does anyone have any ideas on how to improve the health of the female or if anyone can help me with the classifcation. PLEASE!! Thanks
