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.; hinanoae: Named for Hinano Murphy; where Hinano, a popular name among Tahitian women, is also the vernacular Tahitian name for the male flower of the Pandanus plant as well as the name of a popular beer in Tahiti.

Morphology | Morphometrics
soft rays: 8 - 9. This species is distinguished from its congeners by the following characters: cephalic sensory-canal pore pattern group 2, missing only is the IT pore; dorsal/anal ray formula 9/8; some pectoral-fin rays are branched; absence of the fifth pelvic-fin ray or may be rudimentary; trunk with approximately 8 distinct subcutaneous bars, the 2 bars originating over anterior half of anal fin, extending vertically to lateral midline or beyond, and 3 shorter bars originating over caudal peduncle, last of which often being confluent with prominent spot over the centre of the caudal peduncle; no distinct pair of dark spots on pectoral-fin base; male urogenital papilla with prominent lateral folds, cuplike in appearance (Ref. 94084).
Occurs mainly from shallow reefs. At Moorea, collected almost exclusively from patches of rubble around shallow lagoon reefs. Also found in tidepools and adjacent coral reef; rocky shore with porous volcanic rock and large table corals in water beneath rocks (Ref. 94084).
