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; pictifacies: Name from Latin adjective 'pictus' or painted and the female noun 'facies' for face; referring to the bright red spots on the side of the head, similar to those painted on a clown; treated as a feminine compound adjective.

Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 9; Épines anales: 1; Rayons mous anaux: 8. This species is distinguished by the following characters: cephalic sensory-canal pore system complete (pattern 1), with the PITO pore very small; dorsal/anal fin-ray formula 9/8; some of pectoral-fin rays are branched; 5th pelvic-fin ray present; presence of a distinct dark occipital spot (intense in preservative, but visible in life); no series of small dark spots along dorsal-fin bases; 2 separate orange spots behind the eye; distinctive black marks on the underside of the head; side of head with large round red spots; scleral surface of eye with bold dark-brown-and-white markings (Ref. 115282).
This species occurs in shallow fringing reef which is subject to significant terrigenous sedimentation and relatively warm water due to the limited circulation in the large bay of Teluk Saleh. Often found resting on live massive coral colonies (Ref. 115282).
