Conasprella Thiele 1929


Genus Conasprella Thiele 1929 

Type species (by subsequent designation, Tucker & Tenorio 2009): Conus pagoda Kiener, 1847  . Recent , Pacific, Philippines. 

Note. According to Tucker & Tenorio (2009) the genus Conasprella Thiele 1929  is characterised by relatively small-shelled species, the spire is relatively elevated, with beaded early whorls. Cords may be present or absent on the spire whorls, the last whorl has sulci that reach mid-whorl and often the shoulder; the subsutural sinus is deep; an anterior notch is absent; and the protoconch is multispiral. This genus has a Miocene to Recent Indo-Pacific distribution. It is similar in shell characters to the Western Atlantic genus Jaspidiconus Petuch 1993  , which also has a Miocene to Recent record in tropical America (Landau & da Silva 2010), but differs in having tubercles developed along the shoulder carina of the last whorl. Jaspidiconus  , together with Perplexiconus Tucker & Tenorio, 2009  , were considered synonyms of Ximeniconus Emerson & Old, 1962  by Puillandre et al. (2014a), although one can see that each of these groups is distinct, with Perplexiconus  and Ximeniconus  more closely related than Jaspidiconus  . Conus jaspideus Gmelin, 1791  , the type species of Jaspidiconus  , has a symmetrical curved subsutural flexure ( Hendricks 2009), requiring a revised diagnosis of Conasprella  , if Jaspidiconus  is considered as synonym of it, although it is more likely that they are distinct genera; Conasprella  is restricted to the Indo-Pacific, while Jaspidiconus  is tropical American. All Paratethyan species placed in Conasprella  herein have tuberculate early spire whorls and beaded cords on the last whorl. Their subsutural flexures are shallow, moderately to strongly curved and moderately asymmetrical. This is an interesting record as it suggests, amongst others, a Paratethyan occurrence of a taxon nowadays restricted to the Indo-West Pacific.
