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.; readerae: Named for Sally E. Reader. More on authors: Gill & Jewett.

Morphology | Morphometrics
soft rays: 8;
Vertebrae: 26. This species is distinct with the following set of characters: D VI + I, 9; A I, 8; with some pectoral-fin rays branched; fifth segmented pelvic-fin ray is lacking; cephalic sensory-pore system pattern 1; non-fimbriate male genital papilla; dark bars or saddles 12-13 on trunk from origin of spinous dorsal fin to mid peduncular spot, not extending below midline (except in small juveniles); pectoral-fin base with a prominent circular dark spot dorsally (sometimes with additional small diffuse spot ventrally) (Ref. 59013). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).
Specimens were collected from tidal pools, lagoon patch reefs and reef slopes at depths from about 0.3 to at least 30 m (Ref. 59013). Benthic, also found in coral and rock reefs (Ref. 75154).
