Eviota latifasciatus (Jewett & Lachner, 1983)
---------------------------
Description
Dorsal spines (total): 7; Dorsal soft rays (total): 7-9; Anal spine: 1; Anal soft rays: 8-9; Longitudinal scale series 23-25. Body depth: 4.5-5.0 in SL; Scales ctenoid, absent from head, nape, chest and pectoral-fin base; Pelvic fins separate, with a thin membrane joining bases; Fourth pelvic-fin ray with 7-11 branches. Max. length: 1.5 cm SL, usually: 2.0 cm TL. Depth range: 4 - 25 m.
Color
Semi-transparent body with 6-7 large brown blotches or broad bars along the side, sometimes with narrow white bars, and white markings on top of the head, and a dark caudal-peduncle spot over preural centrum centered on lateral midline.
Etymology
Eviota: from Greek prefix, ev-, eu-, = good or well, very + from Greek letter, iota = smallest letter in the Greek alphabet and often figuratively used to describe anything small or insignificant. Referring to Eviota epiphanes (Jenkins, 1903), which, at 1.0-1.9 cm in length, Jenkins claimed was the “smallest vertebrate that has up to this time been described”.
latifasciata: from Latin, latus = wide + from Latin, fasciatus = banded. Referring to broad subcutaneous bars on trunk.
Original description: Eviota latifasciata Jewett & Lachner, 1983 - Type locality: off Bolton Point, Abaiang Atoll, Gilbert Islands, southern Pacific, depth 7.6-10.7 meters.
Distribution
Eastern Indian Ocean and West Pacific: Christmas Island, Indonesia (Sulawesi, Lesser Sundas, Banda, West Papua), north to Japan (Okinawa and Ryukyu Islands) and Micronesia (Palau, FSM [Pohnpei], and Kiribati), east to New Caledonia, Solomon Islands, Fiji, Tonga and French Polynesia (Austral Islands).
Biology
Solitary, rests on bottom. Inhabits exposed coastal reefs and outer slopes.

Eviota santanai (Greenfield & Erdmann, 2013) - Reported from Timor-Leste, Timor.
