Pisinna hipkinsi is a species of marine gastropod mollusc in the family Anabathridae.[1] First described by Winston Ponder in 1965 as Estea hipkinsi, it is endemic to the waters of New Zealand.
Description
[edit]Pisinna hipkinsi has an elongated conic shape, twice the height of its aperture, and had five and half whorls.[2] The species measures 2.38mm, by 1.3mm.[3] It is predominantly a pale yellow color, except for its protoconch which is dark red.[2]
The species is similar in appearance to Pisinna impressa, but can be told apart by the absence of a subsutural incised spiral, and larger size in Pisinna hipkinsi.[2]
Distribution
[edit]The species is endemic to New Zealand.[1] The holotype was collected by R.S. Bird in June 1951 from Spirits Bay at the far north of the Aupouri Peninsula in Northland.[2] While originally described as being exclusively found in the far north of New Zealand, the species has since been identified as far east as the Aldermen Islands,[4] and Snares Islands / Tini Heke, 200 km south of the South Island.[5]
