to posterior margin of caudal fin.<br />

Young male, and young unsexed specimens,<br />

150-195 mm SL (Fig. 31), overall brownish with<br />

dark brown markings. Extrascapular marking<br />

distinct, consisting of dark proximal and distal<br />

blotches. Three dark vertical bars on side (bars<br />

1-3), dorsally slightly separated from dorsal fin<br />

base, becoming gradually narrower ventrally,<br />

extending for } of side. Dark spot on many scales<br />

on back form short irregular rows of spots in<br />

larger specimens; in 150 mm SL specimen entire<br />

dorsum to level of upper lateral line, including<br />

caudal peduncle marbled with dark brown spots<br />

and lighter ground colour. Vertical bar on caudal<br />

peduncle absent. Small dark spots scattered on<br />

side only in 189 mm SL specimen; two larger<br />

specimens with irregular dark, light-margined<br />

spots behind pectoral fin base caudad to bar 3.<br />

Dorsal fin spinous portion dark, soft part with<br />

more or less distinct light spots distally. Anal fin<br />

with 3-4 rows of light spots distally; obsolete in<br />

150 mm SL specimen. Up to five vertical rows of<br />

hyaline spots present posterodorsally on caudal<br />

fin. Caudal blotch round or slightly irregular,<br />

with complete or nearly complete light margin.<br />

Pelvic fin with a few light spots in 195 mm SL<br />

specimen.<br />

In adult female 246 mm SL (NRM 18023)<br />

dorsum and dorsal margin of caudal peduncle<br />

dark greyish brown, nape and snout grey. Side<br />

light brown, abdomen, chest and ventral aspect<br />

of caudal peduncle yellowish white. Side of head<br />

brown, light or dark spots absent. Black spot<br />

marking region of proximal extrascapular. Four<br />

black vertical bars (bars 1-4); anterior below anterior<br />

half of spinous dorsal fin, second below<br />

posterior third of spinous dorsal fin, third below<br />

soft dorsal fin, fourth anteriorly on caudal peduncle.<br />

Bars wider dorsally, but about uniform in<br />

width across side; bars 1-2 extend to level of<br />

lower pectoral fin base, bar 3 slightly shorter,<br />

bar 4 to little below lower lateral line.<br />

Small black spot on medial side of pectoral<br />

fin base and on adjacent side. Side, but not dorsum,<br />

with numerous scattered, partly confluent,<br />

small brownish spots; posterior to bar 2, including<br />

caudal peduncle, also many scattered small silvery<br />

spots. Spinous portion of dorsal fin black.<br />

Soft dorsal fin brown, light spots cannot be traced.<br />

Anal fin brown, soft portion distally grey with<br />

successively more obvious light spots distally on<br />

soft portion, three cross rows of hyaline spots<br />

distally on soft portion. Caudal blotch black,<br />

round, with almost complete silvery ring with<br />

short interruption dorsally and ventrally. Caudal<br />

fin brown, paler ventrally, and with indistinct<br />

pattern of alternating dark and light vertical bars<br />

posteriorly on dorsal lobe. Pelvic fin laterally<br />

brown with about four cross rows of white spots<br />

and lighter margin; medial side grey with some<br />

light spots visible from opposite side.<br />

Large males (Fig. 32) light brown, caudal<br />

peduncle, abdomen and head ventrally whitish.<br />

Snout and occiput dark brown. Postorbital dark<br />

markings absent. Black occipital bar extending<br />

from above gill cover obliquely anteriad across<br />

nape. Dark brown vertical bars 1-2 below spinous<br />

dorsal fin ventrally to about level of pectoral fin<br />

base, bar 3 below anterior half of soft dorsal fin<br />

ventrally to slightly below lower lateral line. Dark<br />

brown blotch anterior to pectoral fin base. Several<br />

dark irregular blotches on abdominal side<br />

under adpressed pectoral fin. Scattered small dark<br />

spots between bars 1 and 2, and dorsally between<br />

bars 2 and 3. Dorsal surface of caudal peduncle<br />

dark brown. Spinous dorsal fin black, soft part<br />

brown with indistinct light spots on three posterior<br />

interradial membranes. Anal fin greyish<br />

brown with indistinct light spots on five posterior<br />

interradial membranes. Caudal fin brownish<br />

basally, otherwise greyish. Caudal blotch black,<br />

ringed with silvery or light spots. Pelvic fin greyish<br />

brown, lighter posteriorly. In 276 mm SL<br />

specimen (holotype, Fig. 32), anal fin with silvery<br />

white spots on inner ‚ of scaled portion, and all<br />

of naked posterior membranes; lower lobe of<br />

caudal fin with about six irregular vertical rows<br />

of silvery white spots; lateral aspect of pelvic fin<br />

with silvery white spots on two anterior membranes<br />

and long stripes of same colour on posterior<br />

membranes. MZUSP 38410 specimens generally<br />

not well preserved, and details of the pigment<br />

pattern on fins cannot be unambiguously determined.<br />

Live colouration. Photographs show breeding<br />

males with yellow or golden side, greenish head<br />

without black spot, white chest, abdomen and<br />

ventral aspect of caudal fin base, but side duskied<br />

close to anal fin base. Vertical bars black. Yellow<br />

colour of side interspersed with numerous small<br />

black spots dorsally. Spinous dorsal fin black,<br />

with only few light spots. Soft dorsal fin, anal fin,<br />

and lateral aspect of pelvic fin grey to blackish<br />

with scattered contrasting white or yellow spots.<br />

Caudal fin ocellus with white to yellow ring.<br />
