I put my R.junceus pair together this week. Within minutes they where dancing, as the male initiated mating almost immediately when he found the female. He approached here while juderring and grabbed her chela. After a half an hour I stopped watching, there was no spermatophore deposition uptill then and the wather was too nice to stay inside 
I have found no spermatophore since then and I still keep the pair together for a couple more days.
