Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 7; 背的軟條 (總數) : 9 - 10; 臀棘: 1; 臀鰭軟條: 8 - 9. This species is distinguished from its congeners by the following characters: dark band on entire lower body from the head back to the caudal-fin base where it intensifies and ends in a semi-circle; pectoral-fin base with small black dots, more intense dorsally; cephalic sensory pore system lacking the PITO and IT pores and the AITO pore enlarged; dorsal/anal fin-ray formula usually 9/8; pectoral-fin rays simple; spinous dorsal elongate or filamentous in both sexes; genital papilla nonfimbriate; in life dorsal half of body yellowish cream in color, ventral half dark gray to black in type material, varying to dark reddish in others (Ref. 87726); characterized further by longitudinal scale series 23-24; ctenoid scales except cycloid on breast, none on head, nape and pectoral fin base; separated pelvic fins, bases joins by thin membrane; well developed fifth pelvic ray; depth of body 3.5-5.1 in SL (Ref. 90102).
Forms groups among branches of Acropora coral, inhabits in sheltered reefs in 2-31 m (Ref 90102).
