More Info


Distribution

Known only from the Cheynes Beach area of southwest Western Australia. Inhabits shallow algal-covered reefs.

Features

Dorsal fin IX, 11; Anal fin III, 9; Caudal fin 12; Pectoral fin 13; Pelvic fin I, 5; Lateral line scales 25.
Body moderately slender (22–24% SL); 1–3 rows of cheek scales and 7–11 large scales on opercle; margin of dorsal-fin membrane weakly incised; caudal fin rounded; pectoral fins short, rounded, middle rays longest.

Colour

Juveniles and females are pinkish-brown above, belly pale pinkish white with 6 darker saddles on the upper half of the body; sides of head with faint narrow blue cross bars; dorsal, anal and caudal fins dusky. 
Males pale to greenish-bronze with a distinct reddish brown stripe on the lower half of the body from the pectoral fin to the caudal and onto anal fin, many lengthwise rows of blue spots and dashes, iridescent and darker on lower half; head pale pinkish brown with 6 nearly parallel narrow iridescent blue bars, curving downwards posteriorly, irregular and broken into spots dorsally; dorsal fins pinkish-brown with rows of blue spots and dashes and iridescent blue border; anal and caudal fins dark reddish-brown with similar blue markings, those on anterior half of caudal fin aligned horizontally, arranged vertically on posterior half, margin iridescent blue.

Feeding

Carnivore - presumably feeds on small benthic invertebrates.

Biology

Presumably a protogynous hermaphrodite like other species of Pictilabrus, with females changing sex to become males at some stage during their life. Females occur in small aggregations.

Fisheries

Of no interest to fisheries.

Conservation

IUCN Red List of Threatened Species: Data Deficient.

Similar Species

Differs from Pictilabrus laticlavius and Pictilabrus viridis, in having a more slender body (4.1–4.5 in SL), weakly incised dorsal-fin membranes, 9 soft anal-fin rays, and 6 parallel blue bars on head (vs dorsal-fin membranes continuous, not incised, anal fin with 10 soft rays, body moderately deep, 2.0–3.0 in SL, head lacking parallel bars).
