I've had a problem with the "chicken spider" epithet from day one. You're taking an imported unidentified spider and calling it by the name of another unidentified spider from a different region. On top of that, you're saying these are the same unidentified spiders based on extremely imprecise behavioral characteristics and itchiness of urticating hairs. There is already enough confusion and hype over the chicken spider (antinous or not? Huge price tag) that I feel like you're forcing the chicken spider name onto it for the perceived rarity and desirability of the spider. I'm not saying that it's not the mythical chicken spider. I am saying that there is simply not enough information to say that it is and forcing the name chicken spider on it (or arana pollito) is only going to make an already confusing situation even worse.
If you read any of the excerpt from the post from the BTS forum that I posted, the differences between P antinous and P whateveryouwanttocallit are clear. Only a taxonomist is going to get so specific to start talking about particular tarsus and what have you. Does it honestly bother you that much? I guess you better get on all of those other Genus sp. notofficial T's that are out there on the market and plead your case for them.
Moreover, there's no price tag! He's not selling them! I don't know if you noticed, but ever since 02-03 when the news of these chicken spiders broke out, there has never been a post on the For Sale/Trade section of this forum until this past Sunday. When there was two. I'm not going to delve into that potential controversy there, but the point is there's no price tag involved here. He saved up the money and shelled it out to go through the proper legal hurdles (Exports, etc.) to get it done. Which can be upwards of $2400. That's a lot if you aren't selling inverts for a living and can justify the expense.
As he stated, he planned it since December of 2008 anyway.
