I adopted 2 of these guys yesterday from a friend, they were classified as B. smithi but as far as i could find B. smithi and B. hamorii have been classified as one Sp. (hamorii) albeit as 2 different localities. Is there a way to differentiate which of the two this is (Colima- or Guerrero-Form?
B hamorii and B. smithi are still categorized as separate species; what makes it especially confusing is that the species that had been called B. smithi was reclassified as B. hamorii while B. annitha is now called B. smithi.
From your photos, I think that both of your tarantulas are B. hamorii, primarily from looking at the tibial banding, but it is harder to say with this individual. There should be bands visible on the chelicerae if it is B. hamorii but I can’t make any out from the photos of this individual, but it could be the lighting.
Oh, they’re sub-adults if not yet mature — how big do you expect this species gets?! XD (And the species should be able to be determined definitively from their molts, if they are female, which there is a good chance of if I am perceiving their size correctly.
Edit: I wanted to post or link some images of the chelicera banding but the forum has those buttons grayed out in responding to your post; I don’t know why. If you take a look at my media, I have a photo posted of my female B. hamorii from 2018 just after a molt and the cheliceral banding is clearly visible.
Oh, they seem so tiny. But you are right sub-adult is probably right. So far i dont know their sex, but fingers crossed for a female
I think i found what you are referring, differences in their spermathecal baseplate right?
They are from 2012 and 2013 respectively so not from the same sack and probably not from the same parents ether.
Fingers crossed i have one of each species the next moults will tell. And you might be right about the sex if they are 9 and 8 years old, i have heard of some males that only matured after 10 odd years but i would guess that to be unusual.

It depends on temperature and feeding. My B. hamorii female matured in only three to four years even with a cooler period over winter. (I got her as a <1” DLS sling early in 2016, was told she was mature from a 2018 molt, and after her last molt in 2019, I paired her in 2020 and this year she gave me over 300 littles ones!)
B. hamorii is most common in the hobby but as far as I can tell, this one could possibly be a B. smithi. The tibial markings on the other individual make me strongly think B. hamorii.

I do believe they were kept at normal room temperature and since i got them very slim i don't think they were fed very often. I haven't gotten a good lock at them ventrally but i personally only note the sex down if i have a molt to confirm it with. They had a B. "smithi" previously to this one that moulted much faster in their care.
Yea the larger one screems hamorii at me too , i do think both will turn out B. hamorii in the end
