Parasite on a Rhinopias

Ok, these things always fascinate me...

Anyone know the latin of this parasite?

Big old nasty isopod. Can't identify it from the photo but the most typical parasites with that look are in the genera Anilocra and Nerocila. Some species attach for a nice hot blood meal then drop off, others stay attached, & yet other species attach then eat their way into the fish.
