Here is the smallest of the two Pseudouroctonus I recieved yesterday from Jason at SSW with a dime for size comparison.The largest is roughly twice as large.

nice photos, great specimen. Beautiful group.

Thanks Zach ! I just hope this is what Kari asked for in the other post and I wonder if it is adult??

Very nice Scott!!!

Thanks Steve!! they are feisty little beasts

TIEEEE-KNEEEEE!!!! That's one itty-bitty reddelli! I would be much surprised if it were an adult. Hmmm, big hands. Interesting for one so small.
Cute little thang, ain't it!

Even one twice that size would still be on the small side of an adult.

Thanks for the photos, Scott!

Thanks Kari! I told you they were tiny I will keep you informed on whether it/they molt again,but I get the feeling they are adult they both have superficial sexual characteristics like you saw in Joels pictures, but I will wait until spring to try and mate them just to be sure.

Mature males will have pectines that are, well, OBVIOUSly larger than usual
So you can go with that to check maturity. I do know that some species mature at various ages/stages/instars/sizes. Among Vaejovis coahuilae, for example, I have seen mature males as small as 33 mm and as large as 45 mm! Females about the same, with the largest at 50 mm!!! I had a little one from Sweetwater, Texas, that was about 33 mm and she has, get this, 42 younguns! (Don't say scorpionlings, it just, well, irks me. )

Really huge differences can be seen in C. vittatus, I've seen mature males as small as 40 mm and as lonnnngggg (like Hadogenes skinny-tail long!) as 80 mm!!!

Thanks!
They are like people then some short some tall so on and so forth.....I will look at the Pectines and try to get pictures I finally bought baggies with no writing on them so I can do it that way.

I will try not to use "scorpling" I hope I get alot of them youngunz maybe even more than 42

OK, I "kinda" calculated that the top reddelli is about 35 mm, right? A dime is 18 mm in diamter.

The holotype male is 46 mm, and the paratype female is 56 mm.

Here is a female from Hays County (not cave, but in a house!) that was about 58 mm:

Both pictures are of the same scorpion but I guessed about the same length.I wonder if the area these 2 were collected were in a sub par area?? and that is why they are smaller but they are probably within the normal lengths from that particular area ;for whatever reason, just small.
