Comparative morphology of Astraea latispina (Philippi, 1844) and Astraea olfersii (Philippi, 1846) (Mollusca, Gastropoda, Turbinidae)

Abstract: The present study examines comparatively the soft parts of turbinids Astraea latispina and Astraea olfersii. The characters of soft parts of these species, in agreement with Trochoidea organization, allow a differencial diagnosis on the cefalic lappets, appendix of eye-stalk, hypobranchial glands, jaws, radulae, and stomach spiral caecum, which information will be helpful in taxonomic studies.Key words: Mollusca, Turbinidae, Astraea, morphology, Brazil. O presente estudo trata do exame comparativo das partes m… Show more

“…The 0.5 whorl long caecum observed in S. obscura (Fig. 31: sc) can also be found in Calliostoma depictum Dall, 1927, but the number of spiral caecum whorls seems to be an inter-specific feature rather than a generic one, because it may vary among congeners such as in Calliostoma and Lithopoma (MONTEIRO & COELHO 2002, DORNELLAS & SIMONE 2013.…”

“…O epipódio de Calliostoma não se difere entre as espécies e inclusive entre as espécies citadas na literatura: C. zizyphinum, C. jujubinum, C. torrei, o qual consiste na presença de quatro pares de tentáculos epipodiais e os lobos do pescoço simétricos (Randles, 1905;Fretter & Graham, 1962;Graham, 1971;Sá & Coelho, 1986;Marshall, 1995a;Harasewych & Sedberry, 2006 Gaza os lobos do pescoço são lisos, mas assimétricos em relação ao tamanho (Monteiro & Coelho, 2002;Simone & Cunha, 2006;Aldea et al, 2009). Randles (1905) relata que o único táxon que apresenta simetria entre os lobos do pescoço é o gênero…”

“…A presença de quatro pares de tentáculos epipodiais em T. viridula, assim como também relatados para outros trocóideos como Astrea (Monteiro & Coelho, 2002), contradiz alguns autores (p.e. Randles, 1905;Graham, 1971) Trochoidea, é uma condição plesiomórfica de Gastropoda (Haszprunar, 1988;Ponder & Lindberg, 1997 (Fretter & Graham, 1962;Bryan, et al, 1997).…”
