Characteristic The snout is broadly elongated with either undulate (in male) or straight (in female) lateral margins, the length is nearly half as long as head; eyes are moderate in size, the diameter is about 1/4 times in the snout, and the trifle is smaller than the width of interorbital space, which is rather flat, and is measured to be 3.5 times in the snout. The tail is thick and the length is little shorter than (in male), or of the same length (in female) of the disc. The pelvic notch is moderate with broad anterior lobe; two dorsals are subequal in length, measuring from 4.0 to 5.5 times in head; caudal fin is small, but always present. The entire dorsal surface except the anterior lobe of pelvic fin covered more or less with relatively thick prickles, which become sparser in the central part of pectorals and above gill-chambers in the adult male, while in the female prickles are developed overall without reduction even in the adult stage; two dorsals and caudal fin and prickled, but pelvic fins are setose only in the central part. One enlarged thorn is present only on each shoulder, instead of being absent, or illegible if present, on nuchal region; a row of the thorns, about 20 in number, are present along the middorsal line of the tail. The ventral side is smooth without prickles. Distribution: Literature: ).
