Clever, Welcome to Spider ID! You got it! I like this species, it looks so big and calm. I can’t go to subspecies level, I didn’t know it had any. Yes this is the ventral plane.

I can’t get the tag to work… At least on my end it’s not actually a link. Oh well.


I can’t add a subspecies, the site isn’t progammed for that. What you wrote is the way we do it, people can refer to what you said. Please don’t worry about the first post. We leave the posts intact as we discuss and reconsider to show our thought process, like my math teachers used to make us do, “show your work.” No, editing doesn’t work except when you are still logged on. Then the cog symbol can give you the option to edit what you just wrote after you hit Enter, but only during the same session. The ratings symbols… Read more »
