Post-marsupial development of Hyalella pleoacuta (Crustacea: Amphipoda): stages 1-4

Abstract: ABSTRACT. The goal of this study is to describe and compare the initial stages of the post-marsupial development of Hyalella pleoacuta González, Bond-Buckup & Araujo, 2006, prior to the development of sexual dimorphism. Ovigerous females were collected in São José dos Ausentes, RS, Brazil and kept in laboratory. Juveniles were kept separately after emerging from the marsupium and were monitored daily for the presence of exuvia. Individuals from post-marsupial stages (S) 1 to 4 were dissected and illustrated.

“…However, important differences are present. Geisler (1944), Stevenson and Peden (1973) and García-Schroeder and Araujo (2009), said that the number of articles in the flagellum of the antennae increases with the size of the animal. In the redescription of González and Watling (2002), H. azteca is larger than the species described herein, but H. maya n. sp.…”
