Israel • 1 spcm; Ashdod; 31.8758°N, 34.6465°E; depth 27 m; 17 May 2017; soft substrate; grab; APM DAN project (sample 8C); size: H 1.1 mm, W 1.4 mm (illustrated specimen) • 1 sh; rocky reef off Sdot Yam; 32.5111°N, 34.8702°E; depth 28 m; 1 Nov. 2018; hard substrate; suction sampler; HELM project (sample S60_2M).

Remarks.

We here report the finding of a living individual of Eunaticina papilla from the Israeli Mediterranean shelf. This juvenile specimen can be assigned to E. papilla because of its overall shape, the sculpture of fine spiral cords, the large umbilicus and the morphology of the thin corneus operculum (Figure 5D ).The species has already been reported in the Mediterranean Sea from Iskenderun in eastern Turkey with a living individual ( Öztürk and Bitlis Bakir 2013). An empty shell was collected near Shiqmona, Israel, in November 2019 and reported as Eunaticina linneana ( Récluz, 1843) ( Schechter and Mienis 2020), a name considered a junior synonym of E. papilla by Beu et al. (2004).
