| The muricid gastropod Concholepas concholepas, known in Chile as 'loco', is an important component of intertidal and shallow subtidal communities, and is one of the main invertebrates targeted by small-scale fishers (divers) in Chile. Because of its ecological importance and economical value, numerous studies have been conducted to describe its life history, ecology and to understand population dynamics, fishery and management. However, little effort has been done to address the causal factor (s) behind its current geographic distribution and moreover little is known about the past distribution of the different species in the genus. In this paper, first we review the paleobiogeography, historical relationships, taxonomy and geographical distribution of... |

| A comprehensive literature review was conducted to determine the species richness of all the possible taxa of free-living benthic marine invertebrates in Chile. In addition, the extent of endemism to the Pacific Islands and deep-sea, the number of non-indigenous species, and the contribution that the Chilean benthic marine invertebrate fauna makes to the world benthic marine invertebrate fauna was examined. A total of 4,553 species were found. The most speciose taxa were the Crustacea, Mollusca and Polychaeta. Species richness data was not available for a number of taxa, despite evidence that these taxa are present in the Chilean benthos. The Chilean marine invertebrate benthic fauna constitutes 2.47 % of the world marine invertebrate benthic fauna. There... |

| Las ascidias (Tunicata: Ascidiacea) Asterocarpa humilis (Heller, 1878) (Styelidae) y Molgula ficus (Macdonald, 1859) (Molgulidae) se registran por primera vez, para la costa de Chile continental. Los ejemplares se recolectaron en los años 1997 y 1998 en tres localidades en los alrededores de la Bahía de Antofagasta, Chile (23º43´S; 70º 26´W), asociados a las agrupaciones de las ascidias Pyura chilensis Molina, 1872 y Ciona intestinalis Linnaeus, 1767, que se fijan en sistemas suspendidos de cultivo de ostiones y en mantos intermareales del «piure de Antofagasta», P. praeputialis (Heller, 1878). En el trabajo se describen las especies y se discuten sus distribuciones geográficas y la posibilidad que ambas hayan sido introducidas o invadido costas de Chile.... |
