Abstract

CLARKE, MARCELA  and  CASTILLA, JUAN CARLOS. Two new records of ascidians (Tunicata: Ascidiacea) for the continental coast of Chile. Rev. chil. hist. nat. [online]. 2000, vol.73, n.3, pp.503-510. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2000000300014.

The ascidians (Tunicata: Ascidiacea) Asterocarpa humilis (Heller, 1878) (Styelidae) and Molgula ficus (Macdonald, 1859) (Molgulidae) are recorded for the first time for the continental coast of Chile. The specimens were collected during 1997 and 1998 at 3 localities in and around the Bay of Antofagasta (23º 43´ S; 70º 26´ W), Chile, in suspended scallop aquaculture ropes, attached to Ciona intestinalis Linnaeus, 1767 and Pyura chilensis Molina, 1872, and in intertidal beds of the sea squirt P. praeputialis (Heller, 1878). This work describes the species and discusses their geographical distribution as well as possibilities for their introduction and/or invasion to Chile. The viviparous condition for A. humilis is communicated. The number of ascidians reported for continental Chile increases from 53 to 55
