You have been an EXTREME help! I've always wanted to see a pic of the tibial spurs on a male Grammastola rosea and you just provided a spectacular view! Do you mind if if I save a copy to my computer just for my own personal use? I knew I had a female, but it ook me two years to figure it out, lol? I'd love to keep a tool like your pic on hand to help me in the future!
