| The terrestrial isopod Atlantoscia floridana (van Name, 1940) occurs from the U.S.A. (Florida) to Brazil and Argentina. In the southernmost Brazilian State, Rio Grande do Sul, the species is recorded in many localities, in urban and in non-urban areas. The growth curve of Atlantoscia floridana based on field data is presented. The specimens were sampled from April, 2000 to October, 2001 at the Reserva Biológica do Lami (RBL), Rio Grande do Sul. Captured individuals were sexed and had their cephalothorax width measured, with the data analyzed with von Bertalanffy's model. The growth curves for males and females are described, respectively, by the equations: Wt = 1.303 [1 - e-0.00941 (t + 50.37)] and Wt = 1.682 [1 - e-0.00575 (t + 59.13)]. The curves showed... |

| This paper presents the description of the three manca stages of the terrestrial isopod Porcelliodilatatus Brandt, 1833 (Porcellionidae). Ovigerous females were collected and kept in the laboratory under controlled conditions (23°C ± 1°C and 14:10 h light:darkness). After birth, mancas (M) were individually reared, and their development was observed. Stages M I, M II, and M III were described based on general characteristics, ommatidia, and appendages. The average development time of each stage was: M I = 18.7 ± 1.5 h (n = 52), M II = 12.7 ± 1.19 days (n = 101), and M III = 12.7 ± 0.45 days (n = 24). Growth was observed using measurements of cephalotorax width. The main characteristics of each stage are presented. |
