Searching foor subadult males of Liphistius

I am searching for subadult males of any Liphistius species. It is easy to differ subadult males of Liphistius from the other stages. Terminal parts of their palps are inflated but without structures typical for adult males. Subadult males in Liphistius occur during spring and summer. I can arrange to pick up specimens at the spider show in Weinstadt, Germany (May 4th).
