Traits examined were (1) head length, which is correlated with total length and mass (Edwards and Cowell, 1992); (2) the sum of first and second antennal segments, which increases with instar (Geisler, 1944; Cooper, 1965); (3) length of tergite spines (mucronations) on the posterior margin of abdominal segments 1 and 2; (4) width of posterior gnathopods in males [these are subchelate thoracic appendages that are strongly sexually dimorphic and influence male mating success (Wellborn, 1993)]; (5) number of eggs in the marsupium, an index of fecundity; (6) egg size, and (7) size at maturity, which was estimated as the size of the smallest gravid female in the population sample.
