This little guy was found near Eugene last week -- the entomologist who found him told me the latin name which I promptly forgot. I've done some digging and I'm pretty sure it's Uroctonus mordax. Any thoughts? The entomologist also said the adults are around twice the size of this specimen. If I've got the species right, how do I sex this one? I think a pectine count would be difficult at best. :wall:

Thanks for any info!

This thread has a picture of the female's pectines, and if you need it that bad, I can go take a picture of my male's pectines. The pectine base is much further apart in females and closer together in males, just like a lot of species. Here is a lo-fi example

\ / female

Definately U.mordax, I got two adults that are about the size of quarters, so it has some growing to do.

Try split operculum & possible visible papillae(male) and fused operculum, no genital papillae (female)

Oh yeah, forgot to mention the operculum, thanks. This site will show you what the operculum is if you do not know.

I think he needs it bad. You should get a pectine shot

It looks like I have a girl!

After she finished playing dead and skittered up my arm:

She's so cute! Thanks for the help, everyone.

Awww...itty bitty pectines :p They're so tiny! The scorpion itself could be crushed by a Pandinus pectine haha.

I have no idea . . . the entomologist who found it didn't say how long it took him to find it or how many there were. All I know is, the next time I go camping I'm bringing a blacklight. :D
