species of the genus (see details in Peña-Santiago &amp; Álvarez-Ortega, in press) in two main aspects. First, its dorsal side is slightly sigmoid (

As far as is known, the functional meaning of this remarkable difference remains obscure. Its taxonomic importance will be a matter for further studies, when more species of the genus are better characterized.
