| This work provides a first taxonomic description of appendicularians collected during September and August of 1995 in the north coast of Chile (18º23'-31º00' S). Fifteen species were identified. They belong to the families Oikopleuridae (Oikopleura longicauda, O. cophocerca, O. dioica, O. rufescens, O. fusiformis, O. albicans, O. gracilis and Megalocercus abyssorum), and Fritillariidae (Fritillaria pellucida typica, F. pellucida omani, F. haplostoma F. tenella, F. formica digitata, F. venusta and F. fraudax). All the species are first records for waters of northern Chile, thus broadening their previous distribution in the southeast Pacific. The most abundant species were Oikopleura longicauda (56.1 %), O. gracilis (10.4 %), Fritillaria pellucida typica... |

| The first description of the larval stages of a representative of the family Rhynchocinetidae from the southeastern Pacific coast of South América is presented. Larvae of the rock shrimp Rhynchocinetes typus, from rocky subtidal environment of the Chile-Pera coast were reared in the laboratory at 22 °C, salinity 32 and feeding with Anemia franciscana. Seven zoeal stages, which occur through 10 successive moults, are described and illustrated in detail. Morphological comparison made between R. typus and other congeneric and related species belonging to Rhynchocinetid showed the main characteristic for the diagnosis of zoeal stages are: (a) the pereiopods appear in the third stage, (b) the exopod of the antennae have six segments, and (c) no pleopods were... |
