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).

Short description
Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng): 7; Các vây lưng mềm (tổng cộng): 9; Tia cứng vây hậu môn 1; Tia mềm vây hậu môn: 8; Động vật có xương sống: 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).
