Kokikora angulata

K. angulata has an angled body whorl and moderately wide umbilicus. The shells are small (typically having a diameter of 1.8 mm (0.071 in), but sometimes up to 2.8 mm (0.11 in)), typically having 4.5 whorls, a depressed turbinate, and are mainly transparent, becoming faintly brown as an adult. The shells have no sculpture, except for irregular growth lines and faint microscopic spirals. The animal has black scratchy marking across the mantle roof, with a yellow white pigment across its visceral coil. Members of the genus have small shells measuring less than 3 mm (0.12 in), are unicoloured, and either turbinate or depressed turbinate, and distinctly but not sharply angled body whorls. The protoconch is mostly smooth, or has a faint spiral sculpture. The genus has post-nuclear whorls that are either smooth, or have a few growth ridges. The animal has some light black markings, and yellow pigment on its visceral coil. It can be differentiated from K. mimiwhangata due to size differences.

K. angulata lives in coastal areas, and rarely in small numbers away from the coast. It is often found in association with epiphytes of remnant trees, often pōhutukawa. Unlike many other coastal land snail species, K. angulata has no preference for limestone. In Auckland, the species is known to occur on the coastal cliffs of Waikōwhai, and small numbers are present in the Auckland Domain, which Climo and Goulstone theorise may have been due to the species remaining in a single location after land reclamations moved the shoreline further north. K. angulata tends to be found in suspended leaf litter.
