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..

(total): 6 - 7;
soft rays: 8 - 9. This species have the complete cephalic sensory-canal pore configuration, pores B', C (unpaired), D (unpaired), E, F, H', N' and O'. It differs from the other species of this subgroup in having the following set of characters: usually 9 dorsal-fin and 8 anal-fin segmented rays; well-developed membranes between pelvic-fin segmented rays; densely pigmented on edge of scale pockets, forming dusky reticulations on body; middle of first dorsal fin with a narrow arc-shaped, diagonal pale band (subtranslucent in preserved specimen); 5-7 diagonal bright-blue to pale-blue bars (translucent and sometimes quite indistinct in preserved specimens) on second dorsal and anal fins in each; 2 ovoid dusky spots on dorsal and ventral parts of pectoral-fin base; absence of an enlarged, distinct subcutaneous dusky spot on mid-lateral caudal peduncle; caudal fin with no conspicuous dusky markings (Ref. 81713).
Inhabits coral reefs (Ref 90102).
