==Description==

* '''Size & shape''': A minute, trochiform (turban-shaped) shell with an elevated spire; adults reach ~'''1.91 mm''' in height and ~'''1.67 mm''' in width; shell color white. * '''Protoconch''': Globose, ~'''{{frac|1|1|2}} whorls''', ~'''260 μm''' in diameter; surface with dense, anastomosing micro-ribs forming tiny alveolar pits (a honeycomb-like micro-sculpture typical for Brazilian ''Brookula''). * '''Teleoconch''': Up to '''3 whorls'''; whorl profile generally convex but slightly flattened just below a '''deep suture'''. * '''Axial sculpture''': Strong, narrow, '''orthocline ribs''' (≈'''24 on the last whorl''' in the holotype); interspaces broad (≈3× rib width); fine microscopic axial lines present in the interspaces. Critically, '''the axial ribs do not enter the umbilicus''' (see Comparisons). * '''Spiral sculpture''': About '''20 thin, regularly spaced cords''' on the last whorl plus base; cords '''cross the axial ribs'''. Around the umbilicus there are '''3–4 stronger spiral cords''' that '''surround and enter''' the umbilical opening.

* '''Aperture & umbilicus''': Aperture rounded, '''holostomate'''; outer lip thin. The '''umbilicus is deep''' (relatively narrow in outline) and circled by the stronger spiral cords noted above. {{Expand section|date=March 2013}}
