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; dorsopurpurea: Name from Latin 'dorsum' for back and 'purpura' for purple; referring to the purple color of the back above the lateral line.

Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 8 - 9; Anale stekels: 1; Anale zachte stralen: 7 - 9. This species is distinguished from its congeners by the following set of characters: a dark band on lower body from snout, across the lower half of the eye back to the caudal-fin base ending in a semi-circle; larger specimens with pectoral-fin base having a reversed L-shaped row of small black dots; cephalic sensory pore system lacking the PITO and IT pores and the AITO pore enlarged; dorsal/anal fin-ray formula usually 9/9; pectoral-fin rays simple; spinous dorsal elongate or filamentous in both sexes; genital papilla nonfimbriate; in life ventral band jet black, and with purple upper half of body and top of head (Ref. 87726); characterized further by having ctenoid scales, none on head, nape and pectoral fin base; separated pelvic fins, thin membrane joins bases; depth of body 4.1-5.6 in SL (Ref. 90102).
Body shape (shape guide): elongated; Cross section: oval.
Forms groups among branches of Acopora coral, inhabits sheltered reefs in 8-30 m (Ref 90102).
