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; irrasa: From the Latin irrasa meaning unpolished or unshaved, in reference to the indiscrete nature of the pigmentation pattern of the head and trunk (Ref. 5289).

背棘 (总数) : 7; 背的软条 (总数) : 9; 臀棘: 1; 臀鳍软条: 8; 脊椎骨: 26. Characterized by the following: base of pectoral fin with two dark circular to oval spots, not sharply defined and often weakly connected, the upper spot somewhat larger than the lower; pectoral spots moderately pigmented, the intensity about equal to trunk bars; head (dorsally) and nape with dark, transverse, bars continuous over dorsal midline, and somewhat more heavily pigmented laterally; trunk with regular, dark, vertical bars, somewhat diffuse in outline, continuous over dorsal midline and usually not extending below midside anteriorly and much shorter posteriorly on peduncle; scale pockets dorsolaterally on trunk often weakly pigmented (Ref. 5289); characterized further by longitudinal scale series 24; ctenoid scales, absence on head, nape and base of pectoral fin; separated pelvic fins, only thin membrane joins bases; 8-11 branches on fourth pelvic ray; depth of body 4.1-4.7 in SL (Ref. 90102). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).
Body shape (shape guide): elongated; Cross section: compressed.
胸鳍基底有两个深色的圆形对椭圆形的斑点, 不是轮廓分明而且时常微弱地连接, 上面的斑点略微大于下面的; 胸的斑点一般有颜色,色彩厚度大约等于躯干横带; 头部 (背面) 与后颈有深色的, 横跨的, 横带连续的背部中线之上, 与略微侧面地的颜色更深的; 躯干有规则又深色的, 纵带, 略微扩散的轮廓, 连续的背部中线之上与通常不前面地向下延伸侧面中央与非常短的在梗后面; 鳞囊背外侧地在躯干上时常模糊的.(参考文献 5289)
