Abstract

ESPINOSA, José; ORTEA, Jesús  and  CABALLER, Manuel. New species of the genus Gibberula (Mollusca: Cystiscidae) from Cuba and Venezuela. Rev. Mex. Biodiv. [online]. 2011, vol.82, n.1, pp.85-91. ISSN 2007-8706.

Three new species of marine molluscs are described. Gibberula palmasola new species, collected in vegetation associated with rocks surrounded by soft sediments in a coastal lagoon surrounded by mangroves in Guanahacabibes Peninsula, Cuba, and characterized by a black head and typical distribution of black and brown bands and orange spots in the mantle. Gibberula dosmosquises new species, collected in rocky bottoms of a Caribbean island from Venezuela, characterized by a simple staining in the mantle and a pattern of spots on the foot, and Gibberula thetisae new species, from sea grass in the gulf of Batabano, Cuba, with shell having 3 columellar folds, the last very weak, and a sharp outer lip; although, its anatomy is not known, these conchological characters separate it from all other known species in the Antilles. Aditionally, the list of valid species for Cuba and Venezuela is discussed and some considerations about Gibberula ubitaensis Espinosa y Ortea, 2000 species complex are given.

Keywords : Neogastropoda; speciation; Caribbean; species complex.
