The dwarfgobies (genus Eviota) are a diverse group of tiny coral-reef fishes (usually <18 mm SL) found throughout most of the Indo-Pacific Ocean. Currently, there are 122 described species (including the new species described herein), with many having been described in the last 10 years. This increase in discoveries is mainly due to selective searching, underwater photography, and collection by diving researchers. Greenfield & Winterbottom (2016) summarized the genus and presented a key, with photographs, to the 107 species described between 1871 and 2016. Greenfield (2017) reviewed the taxonomic history, systematics, reproduction, ecology, geographic distribution, genetic studies, and speciation of the dwarfgobies.
The new species is currently known only from Milne Bay, Papua New Guinea, though presumably is more widespread. Specimens were collected on a sheltered patch reef in Sideia Bay, in 12 m depth, living in small holes in dead-coral pavement between live massive coral colonies
