Última Importance and evolution of sexual dimorphism in different families of Collembola (Hexapoda) PAB Palacios-Vargas,José Guadalupe; Castaño-Meneses,Gabriela. A bibliographic revision of sexual dimorphism in different families of Collembola was performed in order to determine the most common patterns in each group. We list several examples of the sexual dimorphism in different families of Collembola, which illustrate from some of the smallest differences between males and females to major differences between both sexes in some families. We show different cases of sexual dimorphism in Spinactaletes, Sminthurides, and the remarkable morphology of Guthriella muskegis. It seems that most of the cases of strong sexual dimorphism are related to aquatic habitats or behaviour still not fully understood. Species belonging to primarily aquatic families (fresh water or marine water) have the most evolved morphology, where...

A descriptive account is given of the post-embrionic development of Amphilochus neapolitanus Della Valle, 1893 and Ampilhoe ramondi Audouin, 1826 living on Sargassum cymosum C. Agardh, 1820 of Ubatuba, Brazil (23º30'S-45º06'W) through the growth stage based on the morphological changes at each moult. The growth stages are described on the increase of antennal and pleopodal articles number and morphological alterations of gnathopods. The number of stages was found to be different for males and females and the maturity occurs after 6 and 5 post marsupial stages for A. neapolitanus and A. ramondi respectively.
