Color
Body dark reddish to yellowish brown, with narrow white bar from 2nd dorsal-fin spine to mid-abdomen; Large ocellated black spot in front of soft-rayed portions of dorsal and anal fins; Narrow oblique white band rimming rear edge of dorsalfin black spot and crossing body obliquely to outer half of second anal-fin spine; White line across peduncle; Head with two curved white lines passing through each eye, one from upper lip to nape, other from behind corner of mouth to pelvic-fin origin; Caudal fin mostly translucent, with brown rays, brown at base, and broad blackish bar on most of outer half of fin, followed by narrow translucent zone and narrow white margin; Pelvic fins largely covered by reddish black spot, with small white spot at fin origin and on outer white margin.
Etymology
Wetmorella: genus created, in 1928, by Fowler & Beam for Dr. Alexander Wetmore, assistant secretary, United States National Museum, in slight appreciation of his interest in our work on Philippine ichthyology.
albofasciata: from ancient Greek alphós = whiteness, white (properly without luster), dull white + from Latin, fasciatus = banded. Referring to white slightly diagonal bands on body.
Original description: Wetmorella albofasciata Schultz & Marshall, 1954 - Type locality: Mabul Island, off southeastern Sabah, Malaysia.
Distribution
Indo-West Pacific: East Africa, Agalega Islands and Aldabra (Seychelles), Comoros and Madagascar east to Hawaiian Islands (U.S.A.) and Society Islands (French Polynesia), north to Philippines, south to Western Australia, New Caledonia and Tonga.
Biology
Inhabit caves or crevices of lagoon and seaward reefs and drop-offs. Benthic and benthopelagic. Secretive.
