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.; atriventris: The specific epithet is an adjective combining the Latin atrus (black) and venter (belly), referring to the black pigment in the area of the abdomen (Ref. 89418).

Morphology | Morphometrics
soft rays: 7 - 8. This species is distinguished from its congeners by the following set of characters: abdomen with black peritoneum, clearly visible externally; dorsal/anal formula 8/7; simple pectoral-fin rays; length of 5th pelvic-fin ray 40% or greater of 4th ray; genital papilla in male not fimbriate; cephalic sensory-pore system pattern group 2 (only IT missing) (Ref. 89418); characterized further by translucent red with pair of bright yellow stripe behind eye, lower stripe reaching midbody and upper nearly to caudal fin base; fins unmarked; longitudinal scale series 23-24; ctenoid scales, absent on head, nape and pectoral fin base; separated pelvic fins, thin membrane joining bases; 3-5 branches on fourth pelvic ray; depth of body 3.6-4.0 in SL (Ref. 90102).
Lives in small groups near Acropora colonies where it hides when threatened. Feeds on plankton(Ref. 89963). Sometimes solitary, frequently in shady spots near corals (Ref 90102).
