Leptoplana mediterranea ( Bock, 1913)

Synonymous: Leptoplana tremellaris forma mediterranea Bock, 1913

Material examined. Six mature specimens, collected in Isla del Ciervo, Lo Pagán and Los Urrutias (Mar Menor, Murcia). From clays and Caulerpa prolifera (Chlorophyta) found two metres deep; Fig. 1 (4).

Morphological remarks. As described in Gammoudi et al. (2012), the position and structure of the proximal chamber of the prostatic vesicle, and its ventral attachment to the seminal vesicle, are similar in all six specimens and confirms that our exemplars belong to L. mediterranea , supporting the hypothesis that L. mediterranea is the only representative of the genus in the Mediterranean Sea (Gammoudi et al. 2012).

Distribution. Well documented in the Mediterranean Sea (although also reported as Leptoplana tremellaris ) by Grube 1840 (Palermo); Lang 1884 (Naples); Lo Bianco 1888, 1899 (Naples); Pruvot 1897 (Gulf of Lyon); Micoletzky 1910 (Trieste); Palombi 1928 (Port Said), 1936 (Naples); Steinböck 1933 (Adriatic Sea); Arndt 1943 (Naples); Galleni & Gremigni 1989 (Italian coasts); Novell 2003 (Catalonia); Gammoudi et al. 2012 ( Tunisia); and here for Mar Menor (Murcia, Spain).
