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; dalyi: Named for Ryan Daly, who photographed and collected the holotype and played a major role in surveying the fishes of the Seychelles Islands.
Eponymy: Ryan Daly is a South African zoologist and oceanographer who is Research Director (2017– present) at ‘Save Our Oceans’ D’Arros Research Centre. [...] (Ref. 128868), visit book page.

Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 8; Épines anales: 1; Rayons mous anaux: 7. This species is distinguished by the following characters: cephalic sensory-canal pore system lacking only an IT pore (Pattern 2); dorsal/anal fin-ray formula 8/7; pointed pectoral-fin when depressed, branched rays 15; fifth pelvic-fin ray is present and about 20% of fourth; absence of dark markings on head; long, white anterior narial tubes; bright red-and-white markings on head and orange and yellow bars crossing the translucent body (Ref. 120586).
Found associated with either a large massive Porites coral colony or a marginal algal-covered section of the reef with a mix of rubble and hard corals (primarily Acropora spp.) (Ref. 120586).
