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.; tetha: Named for Creusa Hitipeuw, known to her colleagues as 'Tetha'..

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8; Spine anali: 1; Raggi anali molli: 7. This species is distinguished by the following characters: cephalic sensory-canal pore pattern lacking only the IT and NA pores and with the AITO pore positioned far forward and opening anteriorly; anterior tubular nares very long; dorsal/anal-fin formula 8/7; unbranched pectoral-fin rays; fifth pelvic-fin ray absent or flexible and rudimentary and less than 10% of the 4th; a black spot at the caudal-fin base; colour in life red-orange with 5 distinctive small white spots along the posterior midline and 2 white lines over the abdomen (Ref. 96307).
This species occupies a very specific microhabitat and depth range, observed and collected exclusively from a very sheltered and coral-rich lagoon (Kwatisore South Bay) with limited water flow and water temperatures that are commonly elevated above that of the surrounding reef areas (usually 30-31° C). Depth range of occurrence is rather narrow (25-30 m depth) and it was not found either deeper or shallower than this, despite extensive searching. It was found resting and moving about on the surfaces of the extensive foliose and plating coral colonies (mostly Pachyseris and Turbinaria spp. colonies) in the lagoon. Found in association with other coral goby species, including E. atriventris, E. fallax, E. lachdeberei, and Trimma emeryi (Ref. 96307).
