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.; springeri: Named for Victor G. Springer.

Morphology | Morphometrics
soft rays: 7;
Vertebrae: 25. This species is distinguished from its congeners by the following characters: a dark spot at anterior base of first dorsal fin and one medially at end of caudal peduncle; dorsal/anal fin-ray formula 8/7; cephalic sensory pore system pattern 2, no IT pore; unbranched pectoral-fin rays;
first dorsal fin of male may be elongate; the fifth pelvic-fin ray small, one-tenth to three-tenths length of fourth pelvic fin ray (Ref. 92021).
