          Abstract

          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 found on the seven stages. The main difference with related species was the presence of three lacinia in the right mandible at stage VIL.

          Se describe por primera vez el desarrollo larval de un representante de la familia Rhynchocinetidae en aguas del Pacífico suroriental. Las larvas de camarón de roca Rhynchocinetes typus Milne Edwards, 1937 que habita en el submareal rocoso de la costa de Chile-Perú, se cultivaron en laboratorio a 22 °C, con salinidad de 32 y se alimentaron con Anemia franciscana. Se determinaron siete estados de zoea que ocurren a través de 10 mudas sucesivas. Cada uno de los estados se describió e ilustró detalladamente. La comparación morfológica con otras especies congenéricas y otras especies de la familia Rhynchocinetidae indicó que las principales características distintivas de los estados de zoea fueron: (a) el primer par de pereiópodos aparece en la zoea III, (b) el exopodito de la antena presenta seis segmentos, y (c) no se observaron pleópodos en ninguno de los siete estados descritos. La principal característica que diferencia la zoea de R. typus de las demás especies es la presencia de tres lacinias en la mandíbula derecha en el estado VIL.
