I have visit this place again -see habitat photos- a couple of days ago, and could find again a copula from L. erberi, and some individuals, so I can say it is quite regular. This time I did not found Psicolorus but I will come back to try to take a picture from the copula...

Both the copula and the other specimen are
Psilocurus blascoi 
Pay attention to the antennae. Very different from
Laphystia 
Also the mystax is different (very densely haired face in
Laphystia).
