The manca stages of Porcellio dilatatus Brandt (Crustacea, Isopoda, Oniscidea)
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.
