Characteristic Snout moderately long, pointed, 1.3 to 1.6 times the orbit diameter, 40 to 44% of head length, sides of snout convex in dorsal view, its antero-laterai margin completely supported by bone; orbit 28 to 30% of head length; upper jaw 25 to 27% of head length; head ridges very strong, supraoccipital scute developed, several dorsmoedian scutes follow on nape; underside of head naked except for 2 small patches (one below orbit, the other below preopercle angle in largest specimens). First dorsal fin with 2 spines and 8 to 10 rays, its height about equal to or less than the postrostral length of head; pectoral fin rays i16 to i18; inner gill rakers of first arch 0 to 2 +5 to 7. Light organ small, its length 2.1 to 3.5 times into orbital; fossa narrow, extending forward immediately before anus, its anterior end falling well short of level of pelvic fin insertions. Body scales covered with narrowly lanceolate to triangular spinules in 4 to 10 slightly divergent, rivergent, ridgelike rows, the median row strongest; scale rows below midbase of the first dorsal fin 3.5 to 4.5.
