Amblyeleotris katherine (Randall, 2004)
Zebreleotris fasciata (Herre, 1953)
Dorsal spines (total): 7; Dorsal soft rays (total): 10-14; Anal spines: 1; Anal soft rays: 10-12. Max length: 8.0 cm TL. Depth range: 4 - 20 m
Body elongate, compressed; head obtuse, compressed slightly. Interorbital space very narrow, snout obtuse, as long as eye diameter; anterior nostril conical, posterior nostril without rim. Mouth oblique, jaws subequal; maxillary reaching to a vertical line through the posterior part of eye, no barbels. In upper jaw a single external series of about 15 slender caniniform teeth on each side, those in front larger, and an inner band of several irregularly arranged series of small teeth. In lower jaw a cluster ofvilliform teeth in front, and a single series of slender teeth on each side, inside of which 1 to 3 recurved caniniform teeth. No teeth on vomer and palatines. Vomer not notably protruding downward. Tongue rounded, glossohyal bone narrow fan-shaped. Gill opening wide, extending to below the middle of preopercle; isthmus narrow; no fleshy flap on the inner margin of shoulder girdle. No spine on preopercle. Canal pores fully developed, sensory papillae on head poorly defined.
First dorsal fin lower than body, 3rd dorsal spine sometimes filamentous in adult. Second dorsal fin as high as first one, the last ray branched. Anal fin subequal to second dorsal fin in height, rays becoming longer posteriorly, the last ray branched. Caudal fin oblong, its length subequal to head length. Pectoral fins without silky free rays, rounded posteriorly, nearly reaching to a vertical line through the origin of second dorsal fin. Pelvic fins I, 5, with 4th rays longest, uniting membrane not fully developed, fins separated from each other at the posterior margin, UM-value 0.2 to 0.65, pelvic frenum absent.
Scales on anterior half of body small and cycloid, becoming larger and ctenoid posterioly. Head naked, more than ten small scales on median part of nape. Thorax and belly scaly. Small embedded scales on base of pectoral fin.
Colour of body pale yellow with five broad transverse bands of dark reddish purple, slightly inclined forward and downward; anteriormost band running from predorsal to opercle, second from first dorsal to pelvic fin, third and fourth from second dorsal to anal fin, fifth on caudal peduncle; these bands obviously broader than interspace. Narrower band of the same colour on base of caudal fin. From occipital region to posterior part of upper jaw reddish brown. Nape and cheek scattered with many orange-red spots; a part of throat red. Dorsal spines and soft rays yellow, membrane of posterior half of first dorsal fin and whole second dorsal fin yellow with small orange-red spots. Basal half of anal fin dark brown, with blue spots bordered with cobalt blue; along middle of anal fin two narrow stripes, lower orangered and upper blue; distal half of anal fin yellow. Pectoral fin almost colourless. Membrane of pelvic fin dark brown, blue longitudinal lines at part and between basal 5th ray and spine, four blue spots bordered with dark blue on uniting membrane. Caudal fin transparent near distal edge; lower part of basal half dark brown, with blue lines and spots; an orange-red spot at upper quarter of caudal base.
Amblyeleotris: from Greek, amblys or amblus = dull (blade: not sharp), blunt, obtuse + the name of a Nile fish, eleotris.
fasciata: from Latin, fasciatus = banded. In reference to the five broad transverse bands of dark reddish purple on the fish body.
Western Central Pacific: Christmas Island in the eastern Indian Ocean to Samoa, north to the Ryukyu Islands, south to the southern Great Barrier Reef. Reported from New Caledonia.
Moderately common in patches of coarse carbonate or volcanic sand of outer lagoon and seaward reefs. Occurs in pairs and burrow with a yellow species of prawn.
Differs from Amblyeleotris wheeleri (Polunin & Lubbock, 1977) by having narrower red bands and lacking red markings on the second dorsal fin.
