Abstract

The Echinodermata (Echinoderms) is one of the most conspicuous phylum in the marine communities around the southern cone of South America and Antarctica. Many extensive and intensive expeditions in the area have collected an important number of specimens within this phylum. These have been deposited and stored in the Professor Edmundo Pisano V. Biological Collection Room at Instituto de la Patagonia, Universidad de Magallanes (PCEP). This paper presents the first detailed report of the species, families and orders within Echinodermata deposited up until March 2016 in the PCEP. The catalogue of specimens includes 8,589 individuals belonging to the five Echinodermata classes (Crinoidea, Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea). In terms of family per class, Asteroidea is the best represented with 24 families. As a function of the number of number of species per family, Ophiuridae, Asteriidae, and Odontasteridae are the best represented families in the PCEP. The collection is based on 768 admittance records. This includes 67 Echinoderm species from Magallanes (56% of the total number of species reported for the area) and 56 Antarctic species (7.3% of the total reported for this area). Only one species endemic to Magallanes, the Asteroidea Myxoderma qawashqari (Moyano & Larraín Prat, 1976) has been recorded.

The need to continue the recording, taxonomic validation and assessment of the specific richness of Echinodermata in particular, and the benthos present in the austral fjords and channels in general is recommended, given the ecological and biogeographical importance of the region. The importance of keeping and conserving collection or reference collection rooms is underlined given their role in the monitoring of the impact of external pressures and environmental change on the biodiversity of the region.
