This is probably the T. lagocepluilus of some others, but it is not the fish described under that name by Blooh. 

 The latter has a smooth dorsal region like the T. laevigatas, no dermal appendages, and a spotter belly, besides other 

 Characters it. is much more like the T. spmgleriot Bloch, but that species has a more extensive patch of dorsal spines, 

 and a caudal fln of uniform color, besides presenting other generic characters.
