The systematic position of Trigonia Nepos Paulcke, 1903, and Paulckella, a new genus for the Aptian of Chile
Michael R. Cooper, Ernesto Perez, Renato Reyes
Abstract
ABSTRACT. Trigonia nepos Paulcke is a poorly known bivalve from the late Aptian of northern Chile. Although the syntypes are lost, believed destroyed, topotype material shows it to represent a new genus of Pterotrigoniinae for which the name Paulckella gen. nov. is proposed. A neotype is designated and the systematic position of Paulckella gen. nov. discussed. At present it is a South American endemic bivalve. RESUMEN. Trigonia nepos Paulcke es un bivalvo poco conocido, recolectado en estratos del Aptiano superior, norte de Chile. El analisis de la descripcion original, complementado con el estudio de topotipos revelo que, si bien pertenece a la subfamilia Pterotrigoniinae, posee caracteristicas morfologicas ausentes en los generos conocidos. Se propone la creacion de un taxon nuevo, Paulckella gen. nov., hasta ahora endemico de Sudamerica, basado en T. nepos como especie tipo. Se designa un neotipo y se discute la posicion sistematica del nuevo genero.
