Cookeconcha hystricella is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Endodontidae.
The diameter of the shell varies between 5.5 mm and 6 mm, its length attains 2.5 mm.
(Original description in Latin) The shell is umbilicate and discoidal, rather thin, and somewhat closely ribbed and plicate, irregularly rayed with whitish and reddish coloration. The spire is flat or sunken at the center. There are six whorls, swollen below the suture, the body whorl being rounded and not descending. The umbilicus occupies one quarter of the shellâÂÂs diameter. The aperture is oblique and rounded-lunate, constricted by six sharp lamellae â two equal ones on the ventral surface of the penultimate whorl, and four on the basal and right margins. The peristome is simple and straight.
This species occurs on Hawaii.
