Una nova espècie del gènere Moitessieria Bourguignat, 1863 (Neotaenioglossa: Rissooidea: Moitessieriidae) de la Font de la Barrinà (Horta de Sant Joan, la Terra Alta, Catalunya, Espanya)

A new species of the genus Moitessieria Bourguignat, 1863 (Neotaenioglossa: Rissooidea: Moitessieriidae) from Font de la Barrinà (Horta de Sant Joan, la Terra Alta, Catalonia, Spain). Moitessieria barrinae sp. nov. is described on the basis of shells collected at Font de la Barrinà (Massís del Port). The ornamentation of the teleoconch, characterized by a pattern of spiral lines with 5-6 rows of pits superimposed on the subsutural area of each whorl, permits to distinguish the new taxon from the remaining species of this genus. M. seminiana Boeters, 2003 is the species conchologically most similar to M. barrinae, being distinguished from it, besides the homogeneous ornamentation, by the presence of a more marked sinule, the greater convexity of the lower edge of the peristome and the greater inclination of the sutures
