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 (總數) : 7; 背的軟條 (總數) : 9; 臀棘: 1; 臀鰭軟條: 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.
胸鰭基底有兩個深色的圓形對橢圓形的斑點, 不是輪廓分明而且時常微弱地連接, 上面的斑點略微大於下面的; 胸的斑點一般有顏色,色彩濃度大約等於軀幹橫帶; 頭部 (背面) 與後頸有深色的, 橫跨的, 橫帶連續的背部中線之上, 與略微側面地的顏色更深的; 軀幹有規則又深色的, 縱帶, 略微擴散的輪廓, 連續的背部中線之上與通常不前面地向下延伸側面中央與非常短的在梗後面; 鱗囊背外側地在軀幹上時常模糊的.(參考文獻 5289)
