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.; winterbottomi: Named for Richard Winterbottom; noun in genitive case.

Morphology | Morphometrics
soft rays: 8. This species is distinguished from its congeners by the following set of characters: dorsal/anal fin-ray formula 8/8; branched pectoral fin rays 6-7; cephalic sensory-pore system pattern I (complete); absence of fifth segmented pelvic-fin ray; branches on fourth pelvic-fin ray 3-6; non-fimbriate genital papilla; non-filamentous first dorsal fin; slender body 18.8-23.6% SL; spindle-shaped black lines on body (from black pigment in scale-pocket tissue); pigmented anal fin; ventral surface of caudal peduncle with 3 dark marks, 2 more on anal-fin base in preserved specimens; when fresh, 6 internal black blotches on sides (Ref. 83982).
Collected with rotenone and quinaldine (Ref. 83982). Inhabits coral reef crevices in 2-30 m (Ref 90102).
