摘要

摘要1820年，在被描述的93种中，只有10种的形态是已知的。我们描述和说明了新孵化的，第一阶段幼鱼的外部形态，jacutinga maral;marpalal的Teixeira, Páez;索非亚的souza - shibata;Teixeira, 2020使用光学显微镜和扫描电子显微镜(SEM)将它们与其他同系物的同一阶段进行比较，并提供诊断特征。Aegla在形态学上是一个保守的属，这在鉴定其许多隐种时产生了许多问题。因此，有必要通过提供一组新的形态学特征进行分析来完善用于该类群分类的分类特征。

Description of the first-stage juvenile of Aegla jacutinga Marçal & Teixeira in Marçal, Páez, Souza-Shibatta, Sofia & Teixeira, 2020 (Decapoda: Anomura: Aeglidae) from southeastern Brazil

Abstract The morphologies of only 10 of the 93 described species of Aegla Leach, 1820 are known. We describe and illustrate the external morphology of newly-hatched, first-stage juveniles of Aegla jacutinga Marçal & Teixeira in Marçal, Páez, Souza-Shibatta, Sofia & Teixeira, 2020 using light microscopy and scanning electron microscopy (SEM) comparing them with the same stage in other congeners and providing diagnostic characters. Aegla is morphologically a conservative genus, which creates many problems in the identification of its many cryptic species. It thus becomes necessary to refine the taxonomic characters used in the taxonomy of the group by providing a new sets of morphological characters to be analyzed.
