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; nigramembrana: Name an adjective combining the Latin 'nigra' (black) and 'membrana' (membrane), referring to the distinctive black pigment on the opercular membrane.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 1; Raggi anali molli: 8; Vertebre: 26. This species is distinguished from its congeners by the following set of characters: cephalic sensory-pore system pattern group I (complete); dorsal/anal fin-ray formula 8/8; absence of the fifth pelvic-fin ray; 5 internal bands between anal-fin origin and caudal-fin base; pale colour of pectoral fin base and the spinous dorsal fin; presence of a dark rectangular caudal-peduncle spot above midline; no broad dark and light bands; posterior edge of opercular membrane with a concentration of dark chromatophores; in life red-orange spots along bases of both dorsal fins, and belly with distinct red spots (Ref. 93270). Dorsal to anal fin-ray formula 8/8.
Body shape (shape guide): elongated; Cross section: oval.
