Longimanus vs Spinifer granular patterns

[MorbidArachnid]

Hello!

I've seen in a couple keys and identification guides that the best way to tell apart h. spinfer and h. longimanus females is the granulation patterns on their carapaces. Unfortunately I can't seem to find a lot of good pictures of their cephalothoraxes, was wondering if someone could help me out and post pictures.

here are some pictures of my H. spinifer and a side by side between h. spinifer and h. silenus. I don't have a longimanus and honestly these pictures could've been better but I don't have a great macro, so any pics you could post would help.

No this is really helpful! Thank you! I've seen the paper with the shaded region denoting where the granular regions are, but when people talk about "longimanus has granules more linear" and "spinifer have granules more in a curve" its hard to picture that with just shaded regions. The side by side does help tho.
