Further Additions to the Knowledge of the Reproduction of Zonaria pyrum insularum var. nigromarginata (Deprez & Govaert 2009) in the Atlantic and Western Mediterranean Coast of Spain

Abstract

The family Cypraeidae is represented in the Mediterranean Sea by four native species: Luria l. lurida; Naria s. spurca; Schilderia a. achatidea; and Zonaria p. pyrum. These species also inhabit the Atlantic coasts of Europe and Africa beyond the Strait of Gibraltar. Besides these, there are a few Lessepsian immigrants found occasionally throughout the central and eastern part of the Mare Nostrum including Naria turdus var. micheloi and Purpuradusta gracilis notata. This article focuses on the subspecies of Z. pyrum insularum (Schilder, 1928); var. nigromarginata (Deprez & Govaert, 2009), whose populations in the Atlantic have recently been the subject of numerous notes and comprehensive revisions (Goutal, 2008, Bergonzoni, 2013).
