Resumo
The first juvenil stage of Aegla prado Schimitt, 1942 is described and illustrated. The species A. prado showed a direct development, without the swimming free larval form. The most important appendages of the first juvenile stage were analysed: first and second antenna, mandible, first, second and third maxillipeds, first and fifth pereopods, telson and uropods. Setal formula for the first stage and setae characteristics are presented.
