How obvious are C. fimbriatus spurs?

My 4" C. fimbriatus gave me a threat display for the first time. Lo and behold, I see palpal emboli (I think). I still can't see any spurs, but perhaps I'm just blind. Just how obvious are the spurs?

I will try to take some pics of the emboli and spurs but it's rather difficult. The critter won't give me another threat display no matter how much I bother it! I have to gently lift the palps with a pen, but then it's nearly impossible to take a picture.

P.S. Anyone interested in a breeding loan?

Not all species have tibial spurs. Never let the absence of apophyses trick you into thinking you don't have a mature male -- always look at the palps. If you see emboli, he's mature.
Still, pictures would be great

Ultimate males of Chilobrachys do not possess tibial apophyses (spurs).
Todd Gearheart recently asked me if I had a male available, but it was sent off already. Drop him a line.

OK. So what is the difference between emboli and spurs?

Tibial apophyses (spurs) are located on the ventral tibias of leg I in certain species of mature males, and appear as small hooks, used to aid in immobilizing the female during breeding.
All mature males, however, possess palpal bulbs (emboli), which appear as swollen tips of the pedipalps, and are used to insert sperm into the female's spermathecae during breeding.

The spurs are the same thing as the hooks, aka tibial spurs, tibial apophyses. Several months ago, someone posted that this species had hooks. And FWIW, I haven't seen any changes in behavior since he last molted.
