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; vader: Named after the fictional dark figure Darth Vader in the Star Wars movie franchise, referring to the fact that it is the darkest of all described dwarfgobies; noun in apposition.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 7; Raios dorsais (total) : 8; Espinhos anais: 1; Raios anais : 7. This species is distinguished from all its congeners by the following set of characters: with a complete cephalic sensory-canal pore system (pattern 1); dorsal/anal fin-ray formula 8/7; some pectoral-fin rays are branched; presence of a fifth pelvic-fin ray; absence of dark occipital spots or any dark spots at the base of dorsal or caudal fins; with a broad and fringed male urogenital papilla; entire body and fins purplish black (Ref. 137777).
Body shape (shape guide): fusiform / normal; Cross section: oval.
A single specimen was collected from 4 m depth on the reef crest, from a small burrow in the top of a large Porites coral bommie, and this reef crest has many large Porites and other massive corals, transitioning into branching and foliose corals occupying the reef slope at a 45° angle to a maximum depth of 40-50 m (Ref. 137777).
