I don't think so, that this whiptail is H.eigenmanni. This species hasnt this fine drawing like the whiptail on the photos. I think it could be a female H.wolfei.
The picture you found shows a juvenil H.morrowi so the coloration is another as like as yours. Some of the dark spots of the juvenil you can see a bit brighter on your whiptails. But I don't want to commit myself to this species.
