I just realized that both Pseudacanthicus breeding articles contain the same picture of Pseudacanthicus sp. "L 160".
However, in the one on P. leopardus and L 114, it is titled a "gravid female",
while in the new one on P. spinosus, it is termed "male" (as does the catelog-entry for that picture).
Unless there is an unprecenced change in sex of Pseudacanthicus, both can´t be right, I think..
