I thought that variatus had a light body with brown marking and mamoreus was a dark body with light spots, but your question made melon more closely. This paper shows the differences in leg, nippers and sting http://kovarex.com/scorpio/pdf/2019m-Lychas_Mesobuthus.pdf. Sorry your claim to local scorpion fame was so short-lived and down to a mis-identification by me.
