With B.jacksoni the main difference in the sexes (at least for us mortals) is the size of the chela (claw). Males have a stockier more pumped up chela than females. However with only having one it makes it somewhat difficult for you to compare.
Heres a picture of my own pair for you to look at. The male is on the right.
BTW..Notice the colour difference between these adults and your juvenile.
Yours looks like "an older instar 3" or an instar 4. you can see the difference in chela size with the naked eye when they will molt to instar 5.
You cannot sex B.jacksoni by pectinal teeth (18-24 for both sexes).
you can also look at the genital operculum, but this might be very technical for you at this moment..... Just stick to the difference in chela size....
