Procambarus virginalis [from present studs, Vogt (2008), Vogt and Tolles (2004), Vogt et al. (2004)], 2) Faxonius limosus [from Andrews (1907a) and TK unpublished data], 3) Procambarus clarkii [from Andrews (1907b) for Stage I] and Stage III from TK unpublished data. 4) Number of setae was counted from Figures 3, 4, and 7 of Andrews (1907b).
