Overview

General Description

Translated from original description in Poll (1967):

Description of the holotype.  Body depth 4.3 times HL (measured between tip of snout to the posterior edge of opercular opening), 2.5 times in the standard length. Head 5.25 times as long as wide, 2.55 times longer than deep. Snout extended into tube, moderately long, strongly compressed, 8.25 times as long as deep, with chin appendage that is 14.5 times HL, 1.15 times in the eye diameter. Eye 12.35 times in length of head, 9 times in the snout length, 1.1 times in the interoculor width. Dorsal with 31 rays, its base 1.6 times in the distance that separates it from the head, 3.4 times in the distance that separates it from the tip of the snout.  Longest ray 3.35 times in the HL. Anal with 35 rays, its base 1.25 times in the distance that separates it from the head. Longest ray 3.65 times HL. Caudal peduncle 2.7 times as long as deep. Lateral line scales 86, 25 / 21 between the origin of the dorsal and anal, 20 around caudal peduncle.  Teeth 3 / 3.  Brownish, darker on back, a large oblique band between dorsal and anal, not noticeably wider in the middle and followed by a second band behind the fins. All fins grayish.
