So I was looking into the potency of Centruroides margaritatus and I discovered that Centruroides margartitatus is actually overused to describe a lot of scorpions that aren't actually that. I found a revision on the species published in 2011 that separates them from Centruroides edwarsii (which are found throughout Central America), and separates them from some other species that often get confused. I double checked the ones I have and I'm pretty sure the species I have are Centruroides edwarsii. I know C margaritatus have been way more common recently, does anyone happen to know the locality they were collected in or be able to track that down? I would also double check your scorpions if you have C margaritatus. The revision is here: https://www.researchgate.net/public...d_closely_related_species_Scorpiones_Buthidae
"Comparisons. This species was largely confounded
with C. margaritatus, from which it clearly differs by
having pedipalps profusely pilose, hand with dorsal
marginal carina almost smooth and very pilose (Fig. 4
C–D), telson with subaculear tubercle close to aculeus
and directed towards its basal one-third (Figs. 4 G, 6 C,
D), carinae on the pedipalp femur and patella with
smaller and closer granules. Also, when same-sized
adults of both species are compared side-by-side, it becomes evident that both sexes of C. edwardsii have
pedipalps (especially chelae) and metasoma shorter and
more robust than in C. margaritatus (see our Figs. 1–7)."
Which if I'm looking at this correctly seems indicate that Centruroides margaritatus does not have distinctly hairy pedipalps.
These are mine, purchased from PNWarachnids. I know multiple sellers have them right now though and it's likely they came from the same import or from the same person.
