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; atauroensis: Named for its type locality, Atauro Island, Timor Leste.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 7; شعاع نرم باله پشتي (کل) : 9; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 8. This species is distinguished from all its congeners by the following characters: cephalic sensory-canal pore system lacking only the IT pore (pattern 2); dorsal/anal fin-ray formula 9/8; pectoral-fin rays 16, the 4 or 5 lower pectoral-fin rays branched; fifth pelvic-fin ray is rudimentary; male urogenital papilla cup-shaped. Colouration: pectoral-fin base with two distinct dark spots and no additional spot immediately ventral and anterior to pair; 5 dark postanal ventral spots; dark spot on caudal peduncle is centered above midline; first postocular spot a bar of scattered melanophores, second more rounded; (Ref. 131302).
Body shape (shape guide): elongated; Cross section: oval.
Collected from the shallow (0.5–2 m) surge zone, from medium-sized Porites coral bommies, where the individuals were seen resting on the dead coral tops of bommies that are exposed at the lowest tides; dead coral structure is subject to extensive bioerosion creating holes and cracks to shelter the gobies (Ref. 131302).
