This species is distinguished by the following characters: with a supraoccipital bone bearing a highly derived and distinct diamond-shaped bony protuberance oriented anteriorly, rhombus-shaped in anterodorsal view, divided transversally into two sections by a ridge; knob-shaped midventral spine on the cleithral symphysis; blunt midventral spine on the first trunk ring between the pectoral-fin bases; thick dorsomedial crest-like ridge extending over the length of the first trunk ridge; median frontal spine at the convergence of anterior edges of the supraoccipital bone, anterior margin straight-edged; rugose double lateral head spine present below supraoccipital v; three supraorbital extensions or spines, anterior two a double spine and equal in size, the posteriormost spine large and oblong in shape; cleithrum continuous middorsally; presence of supracleithrum; no anterior and posterior nuchal plates, with large gap between the supraoccipital and cleithrum; small blunt midlateral spines proximally on the operculum; cleithral ring with two oval-shaped spines, one spine on anterior to ventral third of pectoral-fin base, the second spine at the ventral extent of the head; small spine on posterolaterally on the pelvic-fin base; four subdorsal spines, forming a square, the dorsal two enlarged, the ventral two small in size (Ref. 132073).
