Abstract

Megalopae of Emerita analoga captured on the central coast of Chile (Coquimbo), are described as complement of the knowledgment of the morphology of the larval development of the species, which have not considered this stage in previous descriptions. The general morphology and structure of megalopa appendices are very similar to that of juveniles of the species, which allow specific identification. Morphological characters, number of segments and setation appendices provide consistent characters for their identification and allow separating them from other megalopae of the genus, despite the great similarity among them.

Highlights

Megalopae of Emerita analoga captured on the central coast of Chile (Coquimbo), are described as complement of the knowledgment of the morphology of the larval development of the species, which have not considered this stage in previous descriptions
Estas características al ser contrastadas con las de la tabla comparativa de Siddiqi & Ghory (2006), en la que confrotan la estructura de los apéndices de E. holthuisi, con las descritas para E. talpoida y E. rathbunae, permiten discriminar estas megalopas con la descrita en esta oportunidad

Summary

Introduction

Megalopae of Emerita analoga captured on the central coast of Chile (Coquimbo), are described as complement of the knowledgment of the morphology of the larval development of the species, which have not considered this stage in previous descriptions. Antenas (Fig. 3c): endito con tres segmentos y un largo flagelo compuesto por 35 a 37 segmentos provistos de setas cortas simples, entre largas setas plumosas curvadas distalmente. Maxílula (Fig. 3e): endito coxal provisto de seis setas en el borde distal y dos más largas y curvadas en el extremo ventral. Endito basal más largo que el coxal, redondeado en el extremo distal.
