Etymology: deminuta: Name from Latin adjective 'deminuta' meaning small, diminutive. Both scientific and common names refer to the tiny size and reduced morphology of this species; noun in apposition.

Morphology | Morphometrics
soft rays: 7 - 8. This species is distinguished by the following set of characters: no sensory pores on head; dorsal/anal formula 8/7; branched pectoral-fin rays; fifth pelvic-fin ray absent; caudal peduncle has a dark spot, typically restricted to above lateral midline; caudal peduncle with a dark blotch over the middle, and a dark bar or crescent over its posterior margin and base of caudal rays (Ref. 94084).
Collected from coral and rocky reefs at depths from 3-41 m; very abundant at Nuku Hiva, where nearly 250 individuals were captured in a single collection between 3-6 m depth (Ref. 94084).
