Abstract
The presence of Solanometra antarctica has been reported in the continental slope of central Chile, however, some studies suggest that this species could have been confused with Florometra magellanica. In this study, 11 crinoid specimens obtained in the continental slope of Central Chile were analyzed and compared with other specimens previously collected in that same region and catalogued as Florometra magellanica. The morphological and meristic characteristics confirm that the crinoids collected in Central Chile, off Concepción and Los Vilos, correspond to Florometra magellanica.
Highlights
En Chile, los equinodermos son uno de los grupos marinos más diversos (~360 especies) y conspicuos (Larraín 1995, Mutshke & Ríos 2006, Martínez et al 2018)

Summary
Nuevos registros de crinoideos (Echinodermata: Crinoidea) en el talud continental de Chile. Abstract.- The presence of Solanometra antarctica has been reported in the continental slope of central Chile, some studies suggest that this species could have been confused with Florometra magellanica. 11 crinoid specimens obtained in the continental slope of Central Chile were analyzed and compared with other specimens previously collected in that same region and catalogued as Florometra magellanica. En el Pacífico Sur Oriental, se han registrado muy pocas especies de crinoideos (< 5, Bohn 2009), dentro de estas se ha señalado la presencia de Solanometra antarctica (Carpenter, 1888) la cual fue registrada frente a Los Vilos, en Chile central (Codoceo & Andrade 1980). El objetivo de este estudio fue realizar una descripción morfológica de los ejemplares recolectados en el talud continental de Chile central, utilizando ejemplares obtenidos de algunos cruceros de investigación y determinar una identificación correcta de la especie presente en las costas de Chile
