Description
Color: In male general coloration light olive gray. A black triangular spot at upper corner of opercle, about as large as pupil. A broad, diffuse, dusky band from lower margin of eye over upper lip and a similar band over middle of upper lip. Opercle and lower half of cheek sprinkled with tiny black dots. Posterior edge of gill membrane narrowly dark, with remainder of throath light and peppered with tiny dark dots, or with entire throat light and peppered with tiny dark dots, or with entire throat evenly dusky. Vertical body bands forked below. At V of ventral fork, and directly above it on upper part of band, a round white spot surrounded by a black circle, these pairs of spots present on five posterior body bands and forming 2 longitudinal, parallel rows of prominent spots along middle of side. Above this an irregular double row of tiny black like those on cheeks, and a few of the same sprinkled on caudal peduncle. Abdomen pale and unmarked. Proximal 2/3 of spinous dorsal dark, mottled, but not definitely stippled or spotted. Beyond this is a row of large brown dots, one on each spine, and an incomplete row of similar, smaller dots. Edge of fin clear. Basal 2/3 of soft dorsal mottled like spinous dorsal. Distal to this are 2 or 3 wavy, narrow dark and light lines parallel to edge of fin, which is clear. Basal 2/3 of anal clear, shading into a very dark submarginal band, with tips of rays lighter, on spots or lines on anal. A pair of small black dots, one above the other, at base of middle caudal rays with a narrow, dusky line extending out unto fin from each, dorsal and ventral edge of fin dusky, but fin otherwise clear and without spots or vertical bands. Base of pectoral light, with a few faded dark dots, fin clear and light except for a rather indistinct, incomplete, single row of dots across basal third of rays. Base of ventrals dusky, fin pale and without markings. Female with a broad, pale line behind eye passing over top of head to meet that of other side, on posterior edge of pale line, opposite eye, two short, black, narrow dashes. A narrow white dash with black border under eye. Indistinct light dots over rest of head. A broad, dark crescent across throat from corner to corner of mouth, occupying mesial 3/4 of throat and separated from dark edge of gill membrane mesially by a narrow, light band. Alternate dark and light bands across lips more sharply defined than in male. Vertical body bands more sharply defined than in male. Double line of dark bordered white spots on side inclined to fade and leave only dusky spots. Numerous characteristic small black dots that stand out sharply against ground coloration scattered indiscriminately over pectoral base and entire body except the lower part of the abdomen. Each vertical body band bifurcate dorsally, sending a splash of brown over base of adjacent rays or fins of dorsal. Membranes of both dorsal mostly clear, 2 or 3 irregular brown blotches on each spine, the smaller distal ones joined together by a faint submarginal dusky band parallel to edge of fin. Outer third of soft dorsal with membrane evenly dusky, basal 2/3 with diffuse brown spots on rays overlapping on to membrane. Anal fin much lighter than in male, submarginal dusky band diffuse, and tips of rays white.

Large males with a low fleshy ridge not 1/3 pupil diameter in height, smaller males and females with no trace of crest. Nasal cirrus with 4 or 5 slender filaments borne palmately on pedicle shorter than filaments, inner filament the longest, entire organ a little shorter than diameter of pupil. Supra orbital cirrus 2/3 eye in height, simple, very slender, and pointed. Nuchal cirrus slender, simple, pointed, a little shorter than pupil. Forehead protruding. Upper lip crenulate along its whole length, lower lip smooth. A single, tiny posterior canine barely emerging from membranes on each dentary. Depth 4.2 to 4.7. Head 5.7 to 6.0. Dorsal notched to about half height between spinous and soft portions, last spine 2/3 height of preceding one, although somewhat buried in membranes of notch. Spinous dorsal about same height as soft dorsal. Membrane from last dorsal rays covering first two small rays of caudal. First few rays not especially elongate or otherwise modified, last anal ray free caudal peduncle. Longest pectoral ray shorter than head by snout and half the eye.
