    I have never heard of that species, but from what I have seen the best way to sex an immature scorpion is to look at the pectines (feathery white sense organs under the scorp). Each looks like it has notches in it. Depending on the species, males and females will have a different number of "notches" in the pectines. You'd would have to find the actual number for the species (or if there is a general number for scorpions), but that is the way to do it. Otherwise, if it is an adult, you can sometimes tell by the length of the tail. Males will have a very long segment right before the telson, where females have a shorter segment. This can be unreliable though. Pics would help, if you can get clear pics of the pectines and the scorp itself :D

    "Pectinal tooth counts above 24 in males and 17 in females"
