Abstract

This paper presents a new Altivasum found off Jurien Bay, Western Australia at 60 m. This new species expands our understanding of the distribution, and in particular extends the northern range of Altivasum, in the South-west Marine Region. Altivasum pauladellaboscae n. sp. is more rhomboidal than A. hedleyi Maxwell and Dekkers, 2019, which is elongated, and has the formation of tubular spines on the shoulder of axial fold on the later whorls of the spire; these spines are not formed in A. pauladellaboscae n sp. Altivasum pauladellaboscae n sp. differs from A. profundum Dekkers and Maxwell, 2018 in having acute shoulder nodules. The South Australian, A. flindersi Verco, 1914 lacks the fibriated subsutural band found in A. pauladellaboscae n. sp. Altivasum clarksoni Maxwell and Dekkers, 2019 is geographically isolated and morphologically distinct, being more elongated and fibriated. This paper brings the number of described Altivasum species to five.
