Ahh There's a website somewhere that lists the species/genera that lack such anatomy, though I forget it.

To be the pointer of the obvious, such species lack these body parts due to the spiders evolving in such conditions that the spurs didn't increase the reproductive abilities, as such they didn't follow "natural selection" and become a stable part of the spider, incresing in size.structure with each generation and evolution. Such cases would be in the larger spiders such as Theraphosa, where possibly due to size, they are redundant. Or in certain arboreal species - noteably the larger ones such as poecilotheria...

Something nice to think about anyway.

Sorry I've been little help.

I wanted to ask this question as per T. blondi (Goliath), and thought I would search first as reading and discovering led me to mixed on whether the male has the spurs. Thanx for covering it. Alas, is there a way then of telling whether my Precious T. blondi is a male of female?

As well, can you or anyone give me the same sexing info for Scolopendra gigantea?:confused:

I don't believe Selenobrachys have them either.

Do you have a reference for this? I have yet to translate the complete description paper for S. phillippinus so I may not have come across this info yet. Any info you can provide would be much appreciated. :)

T. blondi have tibial spurs but is very reduced and dont use it in mating.
