Pandinus spp. and Heterometrus spp.

Males have larger pectines and larger pectine teeth, and the genital operculum is more oval in shape.

Females have smaller pectines and smaller pectine teeth, and the genital operculum is slightly pointed towards the metasoma.

Note: the female pictured here was in poor health so the operculum does not stand out with as much contrast as the male's does.

Is it possible to sex juveniles?

Sure, just look at the operculum shape.

I think that MAY be what mine is, a 3i. The mesosoma is roughly 1 1/2" - 2". I have no clue on the instar.. scratch

It's been around 6 months since I've gotten him/her and hasn't molted yet..

Is this a male or a female? The pectine teeth aren't that long...

Do you think it's an adult?

Here's the pic from when I got "him":

Definitely female. Notice how the genital operculum has a slight point towards the tail-end of the scorpion.

Not sure on adult . . . that telson's borderline between "cream" and "brown." My guess is adult and that the flash kind of washed out the color.

I guess so.. I was just really hoping to have a male and a female pair. For $10/ea. I suppose I can't really complain. That fem looks a bit bulgy in that pic, don't you think?

Don't forget it has to molt still.
So fattening would just be preparation for a molt.
And I guess it is a female :p

ooh yes of course a moult coming up *facepalm* I will wake up now!
After talking about not being an adult too *wake up Connie-love*

well...if a moult keep those temps up *sobs* I learnt the hard way!

But Pandinus Imperator are in the trade so often, you are bound to be able to find a male when you have the money and attempt a mating and a "partnership"

They don't eat when they're coming up to a molt, right? She just ate yesterday; gobbled a cricket down.

I have a juvi emp that's possibly a male. Do you think that it could be sexed at this size? http://img292.imageshack.us/img292/691/spotonspikeae1.jpg

That image was in a thread that I was asking about what the spot was where the arrow is pointing.
