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; bacata: Name from Lartin 'bacatus' meaning 'adorned with pearls', referring to the string of round white spots across the dark abdomen.

Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 7; Anale stekels: 1; Anale zachte stralen: 7. This species is distinguished from all its congeners by the following set of characters: cephalic sensory-canal pore system lacking only IT pore (pattern 2); dorsal/anal fin-ray formula usually 7/7; unbranched pectoral-fin rays, fifth pelvic-fin ray about 20-50% of length of fourth ray. Colouration: peritoneum black, clearly visible and crossed by a yellow-white line on dorsal portion and a row of round white spots on ventral portion, and a vertically elongated black mark at top of pectoral-fin base (Ref. 130976).
Cross section: oval.
Found on all coastal reefs on inshore coastal and lagoonal reefs, including those subject to significant sedimentation (8 m down to at least 30 m), where it frequents complex reef habitat with abundant live coral or rugose rubble areas (Ref. 130976).
