Advena suteri—Suter's striped glass-snail

Conservation significance
Endemic to the Norfolk Island Group.
EPBC Act Listing Status: Critically Endangered (listed as Mathewsoconcha suteri).
Approved Conservation Advice: 19/12/2008 (DEWHA 2008d).

Description
Suter's striped glass-snail (Advena suteri) has an orange-brown to fawn shell with a narrow white peripheral band, a depressed spire, and is 9 to 10 mm in diameter and 6 to 6.5 mm high.

Distribution
Archaeological deposits suggest this species was once common but by 1914 it was considered rare (Iredale 1945; Varman 1991). More recent records suggested it was restricted to isolated localities including Norfolk Island National Park in the area around Mt Pitt and Hundred Acres Reserve (TSSC 2009d). By the late 1990s it had appeared to be extinct in the national park (Varman 2015, 2016).
In March 2020, Suter's striped glass-snail was observed in Hundred Acre Reserve where more than 50 freshly dead shells were observed, but in a period of approximately 6 person-hours of searching, only a single live specimen was found. None of the dead shells were rodent-predated, but the whole area was extremely dry and it is likely that there had been a recent high mortality rate linked to the dry weather (Hyman and Kohler 2020). In May 2021, after more favourable weather, approximately 18 person-hours of searching revealed 52 live specimens, indicating that the population was recovering from the dry period. Based on 2022 surveys, the population size has now grown to 350 individuals over an area of 0.7ha.
