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..

Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 3 m (Ref. 89972). Tropical; 26°N - 32°S
Pacific Ocean: known only from the Society islands, Line Islands and Tuamotu Archipelago. Occurrence in other countries refer to Eviota guttata (restricted to the Red Sea) and E. teresae (Fiji, and as E. cf. terasae in other Western Pacific countries).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.6 cm TL male/unsexed; (Ref. 89972)
This species is distinguished by having a scattering of melanophores obliquely across the pectoral-fin base that is concentrated in the center; two distinct bands of melanophores extending posteriorly from the eye, the upper one is narrow, from eye to above the pectoral-fin base and the lower is broader and extends across the cheek onto the opercle, both of which are the two red bands extending back from the eye when fresh (Ref. 83982); no dark spots on ventral side of head on isthmus (Ref. 113727). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).
Occurs in shallow lagoon and channel reefs at depths usually less than 3 m.
