Tubbreva exaltata is a species of marine gastropod mollusc in the family Anabathridae.[1] First described by Badwn Powell in 1933 as Notosetia exaltata, it is endemic to the waters of New Zealand. There are two subspecies, Tubbreva exaltata exaltata and Tubbreva exaltata sorenseni.
Powell described the species as follows:
The species measures 1.55mm, by 0.9mm.[2]
In 1965, Winston Ponder reclassified the species Notosetia sorenseni (originally described by himself in 1955) as a subspecies of Tubbreva exaltata, due to the two groups' similar appearances. the new subspecies, now known by the name Tubbreva exaltata sorenseni, differs by having a shorter spire and relatively more inflated body whorl.
The species is endemic to New Zealand.[1] The holotype was collected by either A.W.B. Powell or C.A. Fleming in February 1933, offshore from Owenga Beach in the Chatham Islands. It is found in the south of the South Island, the Chatham Islands and the New Zealand Subantarctic Islands,[2] with specimens reported as far north as Taranaki on the west coast of the North Island.[3] [4]
