Description

Shells of Cerion uva can reach a length of 24 mm.[2] This species shows extensive, geographical variations in whorl size.[3] Moreover the shape of these shells change very much as well they grows. Among adults, the shells are beehive-shaped and have an expanded labrum.[2][4][5]

Distribution

This species is endemic to the islands of Aruba, Curacao and Bonaire- many populations are quite different in terms of morphology and represent diverse makeup of infraspecific taxa[6].

Infraspecific Taxa

In 2014, the constituent forms of Cerion uva were reviewed, and included[6]:

  • Cerion uva uva Linnaeus, 1758
    • C. uva uva f. hatoensis Baker 1924
    • C. uva uva f. diablensis Baker 1924
  • Cerion uva desculptum Pilsbry and Vanatta, 1896
  • Cerion uva knipensis Baker 1924
    • C. uva knipensis f. djerimensis† Baker 1924
  • Cerion uva arubanum Baker 1924
  • Cerion uva bonairensis Baker 1924
    • C. uva bonairensis f. kralendijki† Baker 1924


† : Denotes that this name was created to distinguish populations between subspecies, thus being an unavailable name according to the ICZN.
