Aspectos da morfologia interna de Calliostoma (Elmerlinia) jujubinum (Gmelin, 1791) (Mollusca, Gastropoda, Trochidae)

Abstract: São apresentados detalhes da anatomia interna, mandíbulas e rádula de exemplares de Calliostoma (Elmerlinia) jujubinum (Gmelin, 1791), coletados no litoral do Estado do Rio de Janeiro, Brasil. Os estudos confirmaram o típico padrão de mandíbulas e rádula que caracteriza o subgênero Elmerlinia Clench & Turner, 1960. As fêmeas da espécie estudada apresentam uma porção glandular adicionada ao rim direito, mostrando um marcante dimorfismo sexual.

“…Cephalic lappets are structures that may be reduced or absent in species of Calliostoma, as reported by Randles (1905), Fretter & Graham (1977), and Sá & Coelho (1989). According to Risbec (1939), Astraea stellaris (Gmelin, 1791) and Astraea rhodostoma (Lamarck, 1822), both from the Indo-Pacific ocean, have reduced cephalic lappets, whereas in A. latispina and A. olfersii the lappets are developed structures.…”

“…latispina and A. olfersii have jaws formed by chitinous rodlike pieces, more visible on the anterior portion. Randles (1905), Risbec (1939), Graham (1965), Sá & Coelho (1989), and Dekker et al (1992) observed the same feature in other species of trochoids. However, Risbec (1939) showed jaws with a nacre aspect and without rodlike pieces in Chrysostoma paradoxum (Born, 1778), Astraea stellaris, and A. rhodostoma.…”

“…O conhecimento anatômico do gênero Calliostoma é praticamente restrito às espécies C. zizyphinum e C. jujubinum (Fretter & Graham, 1962;Sá & Coelho, 1986). A expansão do conhecimento anatômico a mais 3 espécies do gênero certamente melhora consideravelmente esse quadro.…”
