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; rubrisparsa: Name from Latin 'rubrum' for red and 'sparsus' or sprinkled, referring to the live color pattern of red dots.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 7; Raios dorsais moles (total) : 9; Espinhos anais: 1; Raios anais moles: 8. This species is distinguished from its congeners by the following set of characters: dorsal/anal fin-ray formula 9/8; pectoral fin rays 16-19 (mean 18), 5-6 lower rays branched; cephalic sensory-pore system pattern I (complete); fifth segmented pelvic-fin ray 11.5-22% of fourth; branches on fourth pelvic-fin ray 5-7, 3 segments between branches; non-fimbriate genital papilla; dorsal fin filamentous (to 36.9% SL); body with no distinct large dark marks; anal fin and lower half of caudal fin dark; scattered melanophores behind eyes on nape; when alive, small red dots cover the body but these disappear when preserved in ethyl alcohol (Ref. 83982); characterized further by longitudinal scale series 25; ctenoid scales, none on head, nape, breast and pectoral fin base; depth of body 4.7-5.6 in SL (Ref. 90102).
Inhabits sand-rubble bottoms among reefs in 4-15 m (Ref 90102).
